Parker Chomerics THERM-A-GAP™ GEL T630G Dispensable, Very Low Compression Force, Thermal Gap Filler
Categories: Polymer; Thermoset; Silicone

Material Notes: Description: THERM-A-GAP™ Gels are highly conformable, pre-cured, single-component compounds. The cross-linked gel structure provides superior long therm thermal stability and reliable performance. These unique materials result in much lower mechanical stress on delicate components than even the softest gap-filling sheets. They are ideal for filling variable gaps between multiple components and a common heat sink.

Features/Benefits: Dispensable; Fully cured; Highly conformable at low pressures; No refrigeration, mixing or filler settling issues in storage; Single dispensable TIM can eliminate multiple pad part sizes/numbers; RoHS Compliant and Reworkable

Typical Applications: Automotive electronic control unites (ECUs), engine control, transmission control, braking/traction control; Power conversion equipment; Power supplies and uninterruptible power supplies; Power semiconductors; MOSFET arrays with common heat sinks and Televisions and consumer electronics.

Product Attributes: Years of proven reliability in high-volume automotive applications; General use material; Good thermal performance; Lowest deflection force required; Minimal stress on components and “G” version has 0.010” glass beads as compression stops for electrical isolation.
