GQ0A031871CT Description

The GQ0A031871CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 20-pin QSOP device features 10 isolated resistors, each with a 1.87KΩ resistance and an exceptional ±0.25% tolerance, ensuring minimal deviation in critical circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±25ppm/°C temperature coefficient for reliable operation across a 70°C to 125°C derated power range. Rated for 100V maximum voltage and 0.1W per resistor (1W total), it is ideal for precision analog and digital systems.

GQ0A031871CT Features

• High Precision: ±0.25% tolerance and ±25ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Ceramic case and gull-wing termination ensure mechanical strength and solderability in surface-mount (SMD) applications.
• Isolated Design: 10 resistors with independent isolation (ISOL) minimize crosstalk in multi-channel circuits.
• Compact & Reliable: QSOP package (8.66mm × 6.02mm × 1.47mm) with tight dimensional tolerances (±0.1mm length/height) suits space-constrained PCBs.
• Wide Operating Range: Supports -55°C to 125°C, with derated power up to 125°C for high-temperature environments.
