TO-3 POWER TRANSISTOR SOCKET & MOUNTING KITS E B M60 Section 6 FREV1A1-COLOR 4/4/13 5:35 PM Page 111 SOCKETS FOR TO-3 CASE VARIOUS MOLDED BOSS HEIGHTS MATERIAL: Base: Phenolic, Grade PBE, Type XP Contacts: Brass, Tin Plate Top Plate: Nylon, ASTM-D4066 Phenolic, Grade PBE, Type XP (Cat. No. 4606 only) Collector Plate: Steel, Tin Plate Socket and transistor are assembled to chassis at same time, using the minimum Socket is installed onto chassis using eyelets or screws. Transistor is installed af- amount of hardware. Top molded boss ensure the transistor leads will be isolated from terwards. Assembly and repairs are simplified since socket will stay in place with- the chassis. Various boss heights available to accommodate different out transistor mounted. Top molded boss or added bushing ensure the chassis thicknesses. 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. 1.530 [38.9] 1.188 [30.2] A 1.188 [30.2] .460 .665 [16.9] .521 [13.3] .460 [11.7] A .180 [11.7] REF. [4.6] REF. .730 .430 CAT.
