TO-3 POWER TRANSISTOR SOCKET & MOUNTING KITS 111Tel (718) 956-8900 • Fax (718) 956-9040 (800) 221-5510 • kec@keyelco.com www.keyelco.com 31-07 20th Road – Astoria, NY 11105-2017RoHS COMPLIANT ~ ISO 9001 CERTIFIED SOCKETS FOR TO-3 CASE Socket and transistor are assembled to chassis at same time, using the minimum amount of hardware. Top molded boss ensure the transistor leads will be isolated from the chassis. Various boss heights available to accommodate different chassis thicknesses. Socket is installed onto chassis using eyelets or screws. Transistor is installed af- terwards. Assembly and repairs are simplified since socket will stay in place with- out transistor mounted. Top molded boss or added bushing ensure the transistor leads will be isolated from the chassis. Various boss heights available to accommodate standard chassis thicknesses. Use Cat. No. 4606 and nylon bush- ings for special chassis thicknesses. CAT. NO. A DIM. 4603 .030 (.76) 4602 .045 (1.14) 4601 .090 (2.29) VARIOUS MOLDED BOSS HEIGHTS CAT. NO. A DIM.
