Wurth Elektronik WE-TGF Series Thermal Gap Pad, 4W/mk Thermal Conductivity, Purple - 40014040
This thermal gap pad is a compressible ceramic-filled silicone rubber Interface designed to conduct heat between components and heatsinks while accommodating uneven surfaces and gaps. It operates across a wide temperature range and is intended for electronic cooling applications where a conformable, electrically non-conductive filler is required. The material formulation balances softness with thermal transfer to assist in maintaining component temperatures within operational limits.
Features and Benefits:
• 4W/mK thermal conductivity for improved heat transfer performance
• 35 Shore C hardness to maintain mechanical compliance under compression
• -50 to 180°C operating range for thermal stability in varied environments
• Halogen-free formulation to meet environmental material preferences
• Ceramic-filled silicone construction for electrical isolation during heat conduction
• 35 Shore C hardness to maintain mechanical compliance under compression
• -50 to 180°C operating range for thermal stability in varied environments
• Halogen-free formulation to meet environmental material preferences
• Ceramic-filled silicone construction for electrical isolation during heat conduction
Applications
• Suitable for bridging thermal gaps in power modules and converters
• Used for heat transfer between IC packages and chassis
• Ideal for filling uneven interfaces in LED cooling systems
• Can be used for thermal management in telecoms equipment
• Used for heat transfer between IC packages and chassis
• Ideal for filling uneven interfaces in LED cooling systems
• Can be used for thermal management in telecoms equipment
What are the dimensional options available for this pad?
The pad is supplied in a 100mm x 100mm format with a thickness of 4mm.
How does the material behave mechanically under compression?
The silicone rubber with 35 Shore C hardness provides compressibility to conform to surface irregularities while sustaining contact pressure.
Is the product compliant with common materials regulations?
It conforms to stated halogen-free guidelines and meets REACH and RoHS declarations as provided.
What colour identification does the pad use for assembly processes?
The pad is purple to assist Visual identification during production and maintenance.
What type of thermal filler is used to enhance conductivity?
Ceramic fillers are incorporated into the silicone Matrix to raise bulk thermal transport without introducing electrical conduction.
