Keeping shoulders insulated

Designed to protect transistors and discretes, Bivar has announced the availability of three different styles of shoulder insulators made from a UL rated 40% glass filled Polyphenylene Sulphide.

Designed to protect transistors and discretes, Bivar, Inc has announced the availability of three different styles of shoulder insulators made from a UL rated 40% glass filled Polyphenylene Sulphide (PPS).

These insulators are said to provide grounding protection for the industry’s most popular power transistors while offering added savings in assembly and prevention of 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 stand-offs for added ventilation of mounted devices.

Low in unit cost, these insulators provide added protection in rated uses up to 260 degrees C maximum recommended service temperature, and are chemically inert, with an oxygen rating index over 45%.

Bivar believes they are ideal for use in applications such as power supplies, inverters or other conventional uses of transistors or discretes where sensitivity to assembly or operating temperatures are typically higher than 105 degrees C.

These high temperature machine screw insulators can accommodate screws up to 0.125 inches diameter (3.2mm). Bivar also offers a complete selection of standard service temperature shoulder washers for use in machine screw insulators. They are available in sixty-two different styles and sizes, made from UL rated 94V-2 Nylon material with an oxygen rating over 28%.

These insulating devices reportedly offer a rigid, uniformly moulded chemically inert barrier preventing chassis to component shorting while boasting recommended maximum service temperature of 125 degrees C. They function under a recommended torque of 5 to 6-inch pounds.

Unit pricing is from $37.10/100 each in 25K quantities.
