ITEM 8.01   OTHER EVENTS

            Littelfuse, Inc. ("Littelfuse" or the "Company") announced today
            that it has received the approvals needed under German securities
            law to enable it to fully integrate Heinrich Industrie AG into
            Littelfuse. At their annual meeting on May 12, 2005, Heinrich
            shareholders approved resolutions allowing Littelfuse to combine the
            two businesses and to start a legal process to purchase the
            remaining 2.8% of the outstanding Heinrich shares. The resolution
            allowing Littelfuse to move forward with integration was
            subsequently registered with the German court.
