GUS-QS8A-03-4320-CA Description

The GUS-QS8A-03-4320-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 termination, it offers a 432Ω resistance per element with an exceptional ±0.25% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, with a maximum voltage rating of 100V. Its isolated (ISOL) circuit design ensures independent resistor functionality, while the thin film technology guarantees stability and precision. The EU RoHS non-compliant status may be noted for specific regulatory considerations.
