Parker Chomerics CHO-THERM® 1678 High Power Thermally Conductive Electrical Insulator Pad
Categories: Polymer; Thermoset; Silicone

Material Notes: Description: CHO-THERM® high-power thermal insulator pads are thermally conductive materials designed for use where the highest possible thermal, dielectric, and mechanical properties are required. Fiberglass cloth reinforcement strengthens CHO-THERM® pads against tear, cut-through and punctures. These materials are available in sheet form and die-cut configurations. An optional acrylic adhesive layer (with PSA) is available on one or two sides. With a proven track record spanning several decades in multiple applications, these products are the first choice for high-end power supplies, industrial, aerospace, and military/avionics applications.

Features/Benefits: Excellent thermal properties, High dielectric strength, Excellent mechanical strength and puncture resistance, 100% inspected for dielectric properties on every sheet, PSA attachment option available, Meets RoHS specifications, and Proven through decades of use in demanding military and aerospace applications.

Typical Applications: Power conversion equipment, Power supplies and UPS, Power semiconductors, Automotive electronics, Motor and engine controllers, and Televisions and consumer electronics

Product Attributes: Highest reliability in rigorous applications and Proven in aerospace/defense applications.
