Parker Chomerics CHO-THERM® 1671 2.6W/m-K Conductive Insulator Pads

Parker Chomerics CHO-THERM® 1671 Conductive Insulator Pads offer high thermal conductivity of 2.6W/m·K and strong dielectric properties with a 4kV breakdown. These high-performance, fiberglass-reinforced thermal interface pads operate over a wide temperature range of -60°C to +200°C and provide a thermal impedance of 0.23°C-in2/W (1.48°C-cm2/W) at 300psi. The 1671 series is designed as an alternative to greased mica insulators between discrete power devices and heat sinks. The dry pads have robust mechanical strength and are available with or without a pressure-sensitive adhesive (PSA) acrylic layer for ease of installation. Parker Chomerics CHO-THERM 1671 Conductive Insulator Pads feature a standard thickness of 0.015" (0.38mm) and a thickness tolerance of ±0.002" (±0.050mm).
