Why Choose TG-A1660
Exceptional Thermal Conductivity
At 16.6 W/m·K, the TG-A1660 far exceeds the conductivity of typical silicone pads, which often range from 1 – 6 W/m·K. This allows it to move heat quickly away from high-power components, ensuring lower operating temperatures and longer component life.
Ultra-Soft and Conformable
The material’s low hardness allows it to compress easily, filling microscopic gaps and surface irregularities that would otherwise trap air and reduce thermal performance. This makes it especially effective in applications where surface flatness cannot be guaranteed.
Electrically Insulating
While the TG-A1660 efficiently conducts heat, it also provides strong electrical insulation. This dual functionality eliminates the need for a separate insulating layer, simplifying design and assembly. Many thermal pads have this quality, but at such a high thermal conductivity this is impressive.
Wide Operating Temperature Range
With a temperature tolerance from −50 °C to +180 °C, the pad performs reliably in a wide variety of thermal environments—from cold outdoor conditions to high-temperature power electronics enclosures.
Typical Applications
The TG-A1660 is a high-performance solution for a variety of industries and devices where thermal management is critical:
-
Power electronics and converters
-
Electric vehicles and battery systems
-
5G infrastructure and base stations
-
Industrial automation equipment
-
High-density server and computing modules
-
LED drivers and power modules
Its softness and high conductivity make it particularly suitable for use between high-power components and unevenly surfaced heat sinks or chassis.
Installation and Handling Tips
To get the best performance out of TG-A1660, proper installation is key:
-
Select the correct thickness. Match the pad thickness to the expected gap height to achieve optimal compression and contact.
-
Prepare surfaces. Ensure that mating surfaces are clean and free of dust, oil, or oxidation.
-
Apply even pressure. When assembling, compress the pad evenly to ensure full surface contact without excessive deformation.
-
Secure the interface. Avoid post-installation movement or vibration that could disrupt contact.
-
Verify insulation. In electrically sensitive applications, confirm that no conductive path bypasses the pad.
