Overview
- Hybrid Thermal/EMI Absorber (Thermal Conductive EMI Absorber) has the characteristics of a thermal interface sheet (silicone thermal pad) and a microwave noise suppression function at the same time.
- It has excellent heat conduction (heat dissipation) effect due to excellent thermal conductivity and superior adhesive properties.
- A wide frequency band (1MHz up to 3GHz) and a wide operating temperature range provide excellent product usability.
Features
- Excellent thermal conductivity (Up to 3.0 W/mK)
- Wide frequency band available (1MHz up to 3GHz)
- A wide range of operating temperatures makes it versatile. (-40 to 150ºC)
- It is very flexible and has excellent adhesion to the adherend.
- Excellent flame retardancy
- Can be processed into various shapes according to customer's requirements
