GQ0A022491JAT Description

The GQ0A022491JAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 20-pin QSOP package features 10 isolated resistors, each with a 2.49KΩ resistance (5% tolerance) and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical stability and ease of surface-mount assembly. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for demanding analog and digital circuits.

GQ0A022491JAT Features

• High Precision: Thin-film technology delivers low TCR (±50ppm/°C) and tight tolerance (±5%).
• Robust Construction: Ceramic substrate ensures thermal stability and durability in harsh environments.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm terminal pitch for high-density PCB layouts.
• Isolated Design: 10 independent resistors prevent crosstalk, suitable for multi-channel signal conditioning.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C for sustained performance.
• Surface-Mount Ready: Gull-wing leads facilitate automated assembly and reflow soldering.
