GUS-QS0B-02-2152-CA Description

The GUS-QS0B-02-2152-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 21.5KΩ resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of -70°C to +125°C, with a low ±50ppm/°C temperature coefficient for minimal drift. The gull-wing termination and 0.64mm pitch enable robust PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint saves board space.
