GUS-QS0B-03-3242-BA Description

The GUS-QS0B-03-3242-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP device integrates 19 resistors, each with a 32.4KΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, derated up to 70–125°C for power dissipation. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability systems. Packaged in a gull-wing SMD tube, it combines compact dimensions (8.66mm × 6.02mm × 1.47mm) with robust thin-film technology.
