GUS-QS8A-03-4221-JA Description

The GUS-QS8A-03-4221-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 4.22KΩ resistance and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C. The gull-wing termination and compact 4.9mm x 6.02mm x 1.47mm footprint make it ideal for space-constrained PCB designs.
