GUS-QS8A-02-2551-CA Description

The GUS-QS8A-02-2551-CA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing terminations, this device offers a 2.55KΩ resistance per element with an exceptional ±0.25% tolerance and a low ±50ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, while the thin film technology delivers superior stability and accuracy. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it operates reliably across a wide temperature range of -70°C to +125°C, with a maximum voltage rating of 100V.
