GQ0A031540DT Description

The GQ0A031540DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 154 Ω resistance value and an ultra-tight ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability, with a ±25 ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-density circuits requiring precision and durability.

GQ0A031540DT Features

• High Precision: ±0.5% tolerance and ±25 ppm/°C TCR ensure stable performance in temperature-variable environments.
• Robust Construction: Ceramic case and gull-wing termination provide mechanical strength and solderability for surface-mount (SMD) applications.
• Isolated Design: 10 resistors in an isolated (ISOL) configuration, reducing crosstalk in sensitive analog/digital systems.
• Compact & Durable: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained PCBs.
• Wide Operating Range: Derated power capability from 70°C to 125°C, ideal for industrial and instrumentation use.
