                               EXPLANATORY NOTE

This Post-Effective Amendment No. 1 to Registration Statement on Form S-8
(Registration No. 333-00890) (the "Registration Statement") relates only to
securities issued under the AVX Nonqualified Supplemental Retirement Plan and
the AVX Corporation SERP as successor plans to the AVX Corporation Deferred
Compensation Plan and/or the AVX Corporation Deferred Compensation Plan Trust
pursuant to which such securities are issued. This Post-Effective Amendment
should not be regarded as an amendment to the Registration Statement as it
pertains to securities issued pursuant to the AVX Vancouver Corporation
Retirement Savings and Stock Bonus Plan, also included therein.



                                    Part I
             INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

The document(s) containing the information specified in Part I of Form S-8 will
be sent or given to employees participating in the AVX Corporation SERP and the
AVX Nonqualified Supplemental Retirement Plan (each, a "Plan" and, collectively,
the "Plans") as specified by Rule 428(b)(1) under the Securities Act of 1933
(the "Securities Act"). These documents and the documents incorporated by
reference into this Post-Effective Amendment, taken together, constitute a
prospectus with respect to each Plan that meets the requirements of Section
10(a) of the Securities Act. Capitalized terms used but not defined herein shall
have the same meanings ascribed to them in the AVX Corporation SERP and AVX
Nonqualified Supplemental Retirement Plan.

                                   Part II
              INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.     Incorporation of Documents by Reference.

The following documents filed by AVX Corporation ("AVX") are incorporated herein
by reference:

(i)   AVX's Annual Report on Form 10-K for the year ended March 31, 1999;

(ii)  AVX's Registration Statement on Form 8-A dated July 7, 1995 registering
      its $.01 par value common stock under Section 12(b) of the Securities
      Exchange Act of 1934 (the "Exchange Act").

The following document filed by the Plans (or a predecessor thereof) is herein
incorporated by reference:

Annual Report on Form 11-K for the year ended December 31, 1998 of AVX
Nonqualified Supplemental Retirement Plan (formerly known as the AVX Corporation
Deferred Compensation Plan).

All documents filed by AVX and the AVX Corporation SERP and the AVX Nonqualified
Supplemental Retirement Plan pursuant to Sections 13(a), 13(c), 14 and 15(d) of
the Exchange Act, after the date hereof and prior to the filing of a
post-effective amendment which indicates that all securities offered hereby have
been sold or which deregisters all securities then remaining unsold, shall be
deemed to be incorporated by reference herein and to be a part hereof from the
date of filing of such documents.

Any statement contained in a document incorporated or deemed to be incorporated
by reference herein shall be deemed to be modified or superseded for purposes of
this Registration Statement to the extent that a statement contained herein or
in any other subsequently filed document which also is or is deemed to be
incorporated by reference herein modifies or supersedes such statement. Any such
statement so modified or superseded shall not be deemed, except as so modified
or superseded, to constitute a part of this Registration Statement.

Item 4.     Description of Securities.

Not Applicable.

Item 5.     Interests of Named Experts and Counsel.

None.

Item 6. Indemnification of Directors and Officers.

Section 145 of the General Corporation Law of the State of Delaware (the "DGCL")
provides that a corporation may indemnify any person, including an officer or
director, who was or is, or is threatened to be made, a party to any threatened,
pending or completed legal action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of such
corporation), by reason of the fact that such person is or was a director,
officer, employee or agent of such corporation, or is or was serving at the
request of such corporation as a director, officer, employee or agent of another
corporation. The indemnity may include expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement actually and reasonably incurred
by such person in connection with such action, suit or proceeding, provided such
officer, director, employee or agent acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests and, for
criminal actions and proceedings, had no reasonable cause to believe that his
conduct was unlawful. A Delaware corporation may indemnify officers and
directors in an action by or in the right of the corporation under the same
conditions, except that no indemnification is permitted without judicial
approval if the officer or director is adjudged to be liable to the corporation.
Where an officer or director is successful on the merits or otherwise in the
defense of any action referred to above, the corporation must indemnify him
against the expenses which such officer or director actually or reasonably
incurred.

The registrant's Restated Certificate of Incorporation provides that no director
of the registrant will be personally liable to the registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except to the extent such exemption from liability or limitation thereof is not
permitted under the DGCL as currently in effect or as the same may hereafter be
amended.

                                       2


Pursuant to Section 102(b)(7) of the DGCL, the Restated Certificate of
Incorporation of the registrant eliminates the liability of the registrant's
directors to the registrant or its stockholders, except for liabilities related
to breach of duty of loyalty, actions not in good faith and certain other
liabilities.

The registrant maintains directors, and officers, liability insurance policies.
The By-laws of the registrant provide for indemnification of the officers and
directors of the registrant to the fullest extent permitted by applicable law.

Item 7.     Exemption from Registration Claimed.

Not Applicable.

Item 9.        Undertakings.

(a)  The undersigned registrant hereby undertakes:

   (1) to file, during any period in which offers or sales are being made, a
   post-effective amendment to this registration statement to include any
   material information with respect to the plan of distribution not previously
   disclosed in the registration statement or any material change to such
   information in the registration statement;

   (2) that, for the purpose of determining any liability under the Securities
   Act, each such post-effective amendment shall be deemed to be a new
   registration statement relating to the securities offered therein, and the
   offering of such securities at that time shall be deemed to be the initial
   bona fide offering thereof; and

   (3) to remove from registration by means of a post-effective amendment any of
   the securities being registered which remain unsold at the termination of the
   offering.

(b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13 (a) or Section 15(d) of the
Exchange Act and each filing of the AVX Corporation SERP and AVX Nonqualified
Supplemental Retirement Plan annual report pursuant to Section 15(d) of the
Exchange Act that is incorporated by reference in the Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

(h) Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
