GUS-QS0B-02-3012-DB Description

The GUS-QS0B-02-3012-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 30.1KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it maintains 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-02-3012-DB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length) optimize board space.
• High Power Handling: 1W total dissipation (1/20W per resistor) outperforms similar networks in power density.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Low TCR: ±50ppm/°C ensures minimal resistance drift under thermal stress.
• RoHS Non-Compliant: Suitable for legacy systems where lead-free alternatives are incompatible.
