GUS-QS0B-03-3572-JC Description

The GUS-QS0B-03-3572-JC 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 35.7KΩ resistance value and a 5% tolerance, delivering a total power rating of 1W (0.05W per resistor). Its thin-film technology ensures excellent stability, with a low temperature coefficient of ±25ppm/°C, making it ideal for environments with operating temperatures ranging from 70°C to 125°C. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the compact 8.66mm × 6.02mm × 1.47mm footprint suits space-constrained layouts.

GUS-QS0B-03-3572-JC Features

• Precision Thin Film: Offers superior accuracy (±5%) and stability (±25ppm/°C) compared to thick-film alternatives.
• High Power Handling: 1W total dissipation (0.05W per resistor) with derated performance up to 125°C.
• Robust Construction: QSOP package with gull-wing leads ensures reliable solder joints and mechanical durability.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and automotive-grade circuits (though not PPAP/AEC-Q200 certified).
• Compact & Dense: 19 resistors in a 20-pin QSOP, optimizing board space without sacrificing performance.
• Non-RoHS Compliant: May be preferred for legacy or high-reliability systems requiring leaded components.
