GUS-QS0B-03-4121-JA Description

The GUS-QS0B-03-4121-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 4.12KΩ resistance value and a tight 5% tolerance. It operates within a wide temperature range of 70°C to 125°C (derated) and can withstand a maximum operating temperature of 125°C, making it suitable for demanding environments. With a ±25ppm/°C temperature coefficient, it ensures stable performance under thermal variations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in circuit designs.

GUS-QS0B-03-4121-JA Features

• Thin-Film Technology: Delivers superior accuracy, low noise, and excellent stability compared to thick-film alternatives.
