Designed to protect popular transistors and discretes, Bivar offers three different styles of shoulder insulators made from a UL rated 40% glass-filled polyphenylene sulfide (PPS). The insulators provide grounding protection for the most popular power transistors while offering added savings in assembly and prevention of needed repair or replacement of devices when subjected to high temperatures.
Styles include a traditional shoulder design, flush low-profile and dual-sided low-profile configurations with standoffs for added ventilation of mounted devices. These insulators provide added protection in rated uses up to 260°C maximum recommended service temperature, and are chemically inert (no known solvents under 200°C), with an oxygen rating index over 45%.
These are suited for uses in such applications as power supplies, inverters or other conventional uses of transistors or discretes where sensitivity to assembly or operating temperatures are typically higher than 105°C.
These machine screw insulators can accommodate screws up to 3,2 mm diameter. Also offered are standard service temperature shoulder washers that are ideal for use as machine screw insulators, in 62 different styles and sizes. They offer a rigid, uniformly moulded chemically inert barrier preventing chassis to component shorting while boasting recommended maximum service temperature of 125°C.
