Keystone 4591

Product Overview

A range of transistor sockets and accessories designed for TO-5, TO-100, TO-3, and TO-66 case transistors. These products offer features such as molded barrier insulators to eliminate conventional insulation needs, built-in barriers for sleeving, and molded nylon covers for insulation and temperature resistance. They are designed for ease of assembly, secure mounting, and compatibility with various pin and lead diameters, including wire wrap pins. Some sockets are specifically designed for PC board mounting, eliminating wiring and providing proper spacing for transistor assembly.
