GQ0A023901CT Description

The GQ0A023901CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 3.9KΩ resistance, 0.25% tolerance, and a ±50ppm/°C temperature coefficient, ensuring exceptional stability across a -70°C to +125°C operating range. Encased in a ceramic package, it offers superior thermal performance and durability, with a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating. Its gull-wing termination and 0.64mm pitch make it ideal for surface-mount (SMD) applications requiring compact, high-density layouts.
