GUS-QS0B-03-4221-DB Description

The GUS-QS0B-03-4221-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 4.22KΩ resistance value and an ultra-tight ±0.5% tolerance, ensuring exceptional accuracy in circuit designs. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The ±25ppm/°C temperature coefficient minimizes resistance drift, while the 100V maximum voltage rating enhances durability in high-voltage applications.
