Thermo-silicone caps and tubes

Transcription

1 02 and tubes of the S, C and A series and thermo-silicone tubes of the A series are made of silicone filled with highly thermally conductive ceramics. All-round electric insulation of the component ensures optimal protection (depending on material gauges) against electrical breakdown, while reducing total thermal resistance to the cooling device (heat sink or chassis). are available in different sizes to fit standards TO 220, TO 3P and TO 247. Thermosilicone tubes are available in different diameters. Caps and tubes are ideal for use with Kunze POWER- CLIPS. Application Examples Thermal linkage and electric insulation of heat sources and heat sinks in: Thermal Resistance Overview Caps Power modules Power supplies Electric drives Telecommunication modules Engine control Frequency converters UPS 30
