GQ0A022552FAT Description

The GQ0A022552FAT 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 integrates 10 isolated resistors, each with a 25.5KΩ resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic package, it offers superior thermal stability and durability, making it ideal for harsh environments. With a 0.1W power rating per resistor (1W total), 100V maximum voltage rating, and gull-wing SMD termination, it combines precision with robust mechanical design.

GQ0A022552FAT Features

• High Isolation: Designed for circuit isolation (ISOL), minimizing crosstalk in sensitive analog/digital systems.
• Thin-Film Technology: Delivers low noise, high accuracy (±1%), and tight TCR (±50ppm/°C) for precision applications.
• Ceramic QSOP Package: Enhances thermal performance and mechanical strength vs. plastic alternatives.
• Wide Operating Range: Rated for 125°C max, derated up to 70°C, suitable for industrial/automotive underhood (non-AECQ).
• Compact & Reliable: 8.66mm x 6.02mm footprint with ±0.1mm length/height tolerances for dense PCB layouts.
• Gull-Wing Termination: Ensures secure surface mounting with 0.64mm pitch for automated assembly.
