GQ0A021780FFT

GQ0A021780FFT Description

The GQ0A021780FFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 178 Ω resistance value and a tight 1% tolerance. The ceramic case ensures excellent thermal stability, with a temperature coefficient of ±50 ppm/°C and a power rating of 0.1W per resistor (1W total). Operating within a temperature range of 70°C to 125°C, it supports 100V maximum voltage and is suited for surface-mount (SMD) applications. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB integration. Packaged in a tube, this non-automotive, non-RoHS compliant component is ideal for industrial and telecom systems requiring stable, high-density resistance networks.
