Item 1. Security and Issuer

        This statement relates to the common stock, par value $0.10 per share, of Maxwell Technologies, Inc., 8888 Balboa Avenue, San Diego, California 92123.


Item 2. Identity and Background


Item 3. Source and Amount of Funds or Other Consideration

        All of the shares acquired by Montena SA and reported on this Schedule 13D were received in exchange for all of the outstanding shares of Montena Components, formerly a majority-owned subsidiary of Montena SA. Montena SA borrowed $3 million from the issuer to provide part of the funds required for Montena SA to purchase, prior to such exchange, the shares of Montena Components it did not already own. This loan is secured by 300,000 shares of the issuer's common stock and must be repaid within 120 days of the date on which Montena SA is able to sell issuer shares under a resale registration statement.


Item 4. Purpose of Transaction

        The purpose of the transaction was the acquisition by the issuer of the outstanding capital stock of Montena Components. Montena SA intends to be a long-term holder of most of the issuer stock received in the transaction, subject to its commitment to sell about 300,000 shares of such stock to repay the loan from the issuer described above and the possibility of selling 300,000 to 400,000 shares from time to time to raise cash for its operations. The shares issued to Montena were not registered and can be sold in the public market during the first year following the transaction only under an effective registration statement.

        Montena SA and the issuer have agreed that Jose Cortes, Chairman of Montena SA, will be added as a member of the issuer's board of directors.


Item 5. Interest in Securities of the Issuer


Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

        See Item 4 for a description of the loan arrangement between the issuer and Montena SA.


Item 7. Material to be Filed as Exhibits
