Parker Chomerics CHO-THERM® 1674 1.0W/m-K Conductive Insulator Pads
Parker Chomerics CHO-THERM® 1674 Conductive Insulator Pads feature 1.0W/m·K thermal conductivity, 2.5kV voltage breakdown, 0.41°C-in2/W (2.6°C-cm2/W) thermal impedance. These commercial-grade, silicone and fiberglass thermal pads offer robust mechanical strength and operate in a wide temperature range of -40°C to +200°C. The CHO-THERM 1674 series is offered as dry pads with an optional pressure-sensitive adhesive (PSA) acrylic layer for ease of installation. The pads provide an alternative to greased mica insulators between discrete power devices and heat sinks. Parker Chomerics CHO-THERM 1674 Conductive Insulator Pads come in a standard thickness of 0.010" (0.25mm) with a thickness tolerance of ±0.001" (±0.025mm).
