Leading electro-chemical manufacturer Electrolube has expanded their thermal management range by creating two new high specification, single component RTVs; TCER and TCOR. These 100% solids materials are solvent free and offer a high degree of thermal conductivity. They operate over a very wide temperature range making them ideal for a variety of uses, particularly in automotive applications; the maximum continuous operating temperature suitable for both RTV compounds is 230°C, with short term excursions up to a maximum of 250°C. The use of TCER and TCOR will reduce the equilibrium operating temperature of power devices of all kinds, thus improving lifetime and reliability.
TCER and TCOR are low in odour and cure upon exposure to atmospheric moisture. These RTVs are designed to fill the gap between the device and the heat sink and thus reduce thermal resistance at the boundary between the two. They can be applied around components such as capacitors and power resistors to dissipate excess heat to heat-sinks, avoiding any overheating and subsequent failures. Electrolube features the new products at this year productronica show (hall A4, stand 271).
