GQ0A021822CT Description

The GQ0A021822CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP device features 10 isolated resistors, each with a 18.2KΩ resistance, a tight 0.25% tolerance, and a low ±50ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability, with 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 precision analog circuits. Its gull-wing termination and surface-mount design ensure reliable PCB integration.

GQ0A021822CT Features

• High Precision: 0.25% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case provides excellent thermal and mechanical stability.
• Isolated Design: 10 independent resistors (ISOL configuration) prevent crosstalk in multi-channel systems.
• Compact & Reliable: QSOP package (8.66mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances for high-density layouts.
• Wide Operating Range: Derated power up to 125°C, ideal for industrial and automotive environments (though not PPAP/AEC-Q200 qualified).
