ITEM 5.03  AMENDMENTS TO ARTICLES OF INCORPORATION OR BYLAWS; CHANGE IN FISCAL
           YEAR.

         On May 2, 2006, the Board of Directors (the "Board") of American
Technical Ceramics Corp. (the "Company") amended and restated the Company's
By-Laws (the "Amended By-Laws"). The Amended By-Laws include the following
material substantive additions, deletions, changes and clarifications:

     o    The use of various means of electronic communication and transmission
          to, among other things, conduct meetings of stockholders and provide
          notice to stockholders, is specifically permitted under the Amended
          By-Laws.

     o    The period of time by which (i) notice of each meeting of stockholders
          shall be given before the date of such meeting, or (ii) the Board may
          fix a record date for the determination of stockholders entitled to
          vote or, among other things, receive dividends, was changed from 50
          days to 60 days.

     o    In order to better reflect the current executive composition of the
          Company, the offices of Vice Chairman, Chief Executive Officer ("CEO")
          and Executive Vice President were added to various provisions of the
          Amended By-Laws. The Amended By-Laws specifically clarify that the
          President shall serve as the CEO unless a separate CEO is appointed
          and the principal financial officer shall be the Treasurer unless the
          Board designates another officer to serve as such.

     o    The number of directors that constitutes a quorum at meetings of the
          Board was changed from one-third to a majority of the entire Board.

     o    The determination of officers' salaries may be fixed by a committee of
          the Board appointed for such purpose.

     o    The Amended By-Laws, among other things, (i) describe in more detail
          the standards, procedures, and limits applicable to indemnification of
          the Company's directors and officers and other persons; (ii) expressly
          designate indemnification as a contractual right; (iii) expressly
          provide indemnitees with the right to payment of costs, charges, and
          expenses incurred in an indemnitee's defense of an action in advance
          of its final disposition, provided, that an indemnitee undertakes to
          repay all amounts so advanced if it is ultimately determined that such
          indemnitee is not entitled to indemnification; (iv) permits an
          indemnitee to bring suit against the Company if the Company fails to
          make the payments set forth in (iii) above within the applicable time
          period; (v) extends the rights of indemnification and advancement of
          expenses to a person who has ceased to be a director, officer,
          employee or agent and to the heirs, executors and administrators of
          such a person; (vi) allows indemnification to be retroactive in the
          event of the repeal or modification of the by-law providing for the
          right of indemnification; and (vi) specifically authorize the Company
          to purchase and maintain insurance on behalf of directors, officers,
          employees or agents of the Company, or any related entity thereof,
          against any expense, liability or loss, whether or not the Company
          would have the power to indemnify such person against such expense,
          liability or loss under Delaware law.





     The preceding is qualified in its entirety by reference to the Company's
Amended By-Laws, which are attached hereto as Exhibit 3.1 and are incorporated
herein by reference.
