Lineup of heat countermeasure parts
Achieving high thermal conductivity using graphite Hybrid Solutions: WE-TGFG series
■ Overview
・Thermal conductivity: 400 W/(m ・ K)
・Electrical insulation: 1kV/mm
・ Hybrid Solutions: Applicable as Gap Filler and Heat Spreader
・Standard lineup includes thicknesses from 2 to 25 mm that can be applied to a wide range of applications.
・Size, shape, etc. can be customized
- Replacement of conventional heat dissipation silicone fillers
Product details are available here.
■ Usage example
Even if the space between the IC and the case is narrow and it is not possible to place a heat sink on top of the IC, WE-TGFG can accommodate this. Heat can be spread from the IC to the case or heat sink.
WE-TGFG can also be customized to fit housings of various shapes.
Heat Spreader to spread heat
■ Overview
This graphite sheet boasts extremely high thermal conductivity (1800 W/mk). It can be attached to enclosures and other surfaces to dissipate localized heat from devices. Using it in conjunction with a gap filler provides even more effective thermal management. A gasket type is also available for situations requiring non-planar thermal conductive materials or non-silicone gap fillers.
Product details are available here.
■ Usage example
The above figure is an example of the combination of Heat Spreader and Gap Filler. It is used in the form shown above between the IC and the case or heat sink. We can customize the size, shape, adhesive, etc. Please feel free to contact us.
Gap Filler to lower thermal resistance
■ Overview
This is a silicone-based thermal conductive sheet. It reduces thermal resistance by filling gaps between heat-generating devices and heat sinks, or within enclosures. There are four series with different thermal conductivity and strengths, and there is also a phase change material (PCM) that becomes gel-like as the temperature rises, which can be used as an alternative to liquid materials.

Heat sink that dissipates heat
■ Overview
This thermal management component is designed for PCB mounting and is intended for heat dissipation of lead (TO package) devices and flat package ICs. The aluminum heatsink efficiently dissipates heat from the heat-generating device into the surrounding space, contributing to the suppression of temperature rise in natural air-cooled environments.
Furthermore, we also offer models that come pre-equipped with thermal conductive material to enhance heat transfer between the heatsink and the device, reducing assembly work and minimizing variations in heat dissipation performance.
