A new electrically insulating phase-change material simplifies and speeds the implementation of thermal management solutions.
Designed for high-performance applications where optimal heat transfer is essential, Sil-Pad A2000 is composed of an elastomeric material reinforced with glass fibre.
This yields an outstanding thermal conductivity specification of 3.0W/mK, combined with exceptional electrical characteristics: a relative permittivity of 7.0 (at 1kHz), volume resistivity of 100Gohm-m, and dielectric breakdown voltage of 4kV AC.
Supplied in thicknesses of 0.381 to 0.598mm, Sil-Pad A2000 is more compliant than standard thermal management products, inherently lowering losses at the interface between materials.
This reduction in interfacial losses produces a material with TO-220 thermal performance of 2.05C/W, at a contact pressure as low as 69kN/m2.
The material is designed for continuous use across a wide temperature range (-60 to +200C).
Sil-Pad A2000 is the latest in Bergquist's extensive range of thermally conductive, electrically insulating Sil-Pad materials.
Like all Sil-Pad materials, Sil-Pad A2000 provides a clean and efficient alternative to the use of mica, ceramics or grease in thermal management for electronic assemblies.
In particular, the use of Sil-Pad materials can eliminate the risk of cracking or breakage caused by the brittle nature of mica, which must be used in combination with grease to obtain electrical isolation.
