GUS-QS8B-03-3012-B Description

The GUS-QS8B-03-3012-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 30.1KΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy. The network operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, making it suitable for harsh environments. Its ±25ppm/°C temperature coefficient guarantees stable performance under thermal variations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical characteristics for precision circuits.

GUS-QS8B-03-3012-B Features

• High Precision: 0.1% tolerance and ±25ppm/°C TCR for critical analog/digital signal conditioning.
• Compact & Reliable: QSOP-16 surface-mount package (4.9mm x 6.02mm x 1.47mm) with gull-wing terminals for automated assembly.
• Robust Performance: Thin-film technology ensures low noise, high stability, and long-term reliability.
• Wide Operating Range: -70°C to +125°C with derated power, ideal for industrial and automotive (non-AECQ) applications.
