Wurth Elektronik WE-TGF Series Thermal Gap Pad, 5mm Thickness, 3W/mk Thermal Conductivity - 40003050

This thermal gap pad provides a compliant Interface for heat transfer between uneven surfaces in electronic assemblies. It uses a ceramic-filled silicone elastomer to bridge gaps and reduce thermal impedance while remaining flexible across a wide temperature span. The product is supplied as a blue sheet intended for use where a halogen-free, environmentally declared thermal Interface is required.

Features and Benefits:

• 3W/mK thermal conductivity for improved heat transfer performance
• Ceramic-filled silicone formulation for electrical isolation and thermal path
• 20 Shore C hardness for effective surface conformity under light pressure
• -50°C to 180°C operating range for broad thermal stability
• Halogen-free composition to meet strict material content requirements

Applications

• Suitable for filling Air gaps in power conversion modules
• Ideal for interfacing heat spreaders and enclosure walls
• Used with high-density electronic assemblies requiring electrical isolation
• Can be used for thermal management in LED arrays
• Suitable for prototyping and custom thermal solutions

What physical form is the material supplied in?

It is provided as a flexible blue pad sheet measuring 400 x 200mm and 5mm thick.

How does the pad handle regulatory substance restrictions?

It conforms to halogen-free standards and carries REACH declaration and RoHS compliance information.

What mechanical characteristic affects compression and conformity?

The material's 20 Shore C hardness determines its compressibility and Ability to fill uneven gaps.

What temperature extremes can the pad tolerate during operation?

It operates across a range from -50°C up to 180°C.
