GUS-QS0B-03-1202-CB Description

The GUS-QS0B-03-1202-CB 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 12KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.

GUS-QS0B-03-1202-CB Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), ideal for high-density PCBs.
