GUS-QS8A-03-1213-BB Description

The GUS-QS8A-03-1213-BB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. With a 121K Ohm resistance value and an ultra-tight 0.1% tolerance, this component ensures exceptional accuracy in signal conditioning, voltage division, and impedance matching circuits. Packaged in a 16-pin QSOP (Quarter Small Outline Package) with gull-wing terminations, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained PCB designs. The isolated (ISOL) circuit designator allows independent resistor operation, enhancing flexibility in circuit configurations. Rated for 0.75W (3/4W) total power dissipation and 100V maximum voltage, it operates reliably across a -55°C to +125°C temperature range, supported by a low ±25ppm/°C temperature coefficient for stable performance under thermal stress.
