GQ8A0373R2CCT

GQ8A0373R2CCT Description

The GQ8A0373R2CCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 8-resistor array features a 73.2Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while its isolated (ISOL) circuit configuration prevents crosstalk between channels.
