GQ0A0373R2DCT Description

The GQ0A0373R2DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 73.2Ω resistance and an ultra-tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case provides superior thermal stability, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across a wide operating range (70°C to 125°C). Rated for 100V maximum voltage and 1W total power dissipation (0.1W per resistor), this network is ideal for space-constrained, high-reliability designs.
