GUS-QS8A-03-3921-DA Description

The GUS-QS8A-03-3921-DA 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 3.92KΩ resistance per element with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. Its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. The isolated (ISOL) circuit design allows independent resistor operation, enhancing flexibility in circuit design.
