GQ0A031871BAT Description

The GQ0A031871BAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 1.87KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a ±25ppm/°C temperature coefficient. The gull-wing termination enables reliable surface-mount (SMD) assembly, while the 0.64mm terminal pitch accommodates high-density PCB layouts.

GQ0A031871BAT Features

• Precision Performance: 0.1% tolerance and ±25ppm/°C TCR for stable operation in temperature-variable environments.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• High Power Handling: 1W total power rating (0.1W per resistor) with 100V maximum voltage rating.
• Compact & Reliable: 8.66mm x 6.02mm x 1.47mm dimensions (±0.1mm tolerance) suit space-constrained designs.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent cross-talk in multi-channel systems.
• Industrial-Grade: Non-automotive (PPAP No) but ideal for test equipment, medical devices, and industrial controls.
