GQ0A039101DAT Description

The GQ0A039101DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP device features 10 isolated resistors, each with a 9.1K Ohm resistance, 0.5% tolerance, and a ±25ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C temperature range. The gull-wing termination and surface-mount design ensure easy integration into compact PCB layouts.

GQ0A039101DAT Features

• Precision Performance: Thin-film technology delivers low TCR (±25ppm/°C) and tight 0.5% tolerance for accurate signal conditioning.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength, ideal for harsh environments.
• High Density: QSOP package (8.66mm x 6.02mm x 1.47mm) with 20 gull-wing terminals maximizes space efficiency.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Wide Operating Range: Supports -55°C to 125°C with derated power up to 125°C, ensuring reliability in extended conditions.
