GUS-QS8A-02-4121-JA Description

The GUS-QS8A-02-4121-JA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing terminations, it offers a 4.12KΩ resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient. The device operates over a wide temperature range of 70°C to 125°C (derated) and withstands a maximum voltage of 100V, making it suitable for demanding environments. With a 0.1W power rating per resistor and 0.75W total power dissipation, it balances compactness (4.9mm × 6.02mm × 1.47mm) with robust performance. The isolated (ISOL) circuit design ensures minimal crosstalk, ideal for signal integrity-critical systems.
