GQ0A026490FT Description

The GQ0A026490FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for isolation (ISOL) circuit applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a resistance value of 649Ω and a tight 1% tolerance, ensuring consistent performance in demanding environments. The ceramic case construction provides excellent thermal stability, supporting operation across a -70°C to +125°C temperature range with a low ±50ppm/°C temperature coefficient. Rated for 100V maximum voltage and 0.1W (1/10W) power dissipation per resistor, it delivers a total power rating of 1W, making it suitable for precision analog and digital circuits.

GQ0A026490FT Features

• High Isolation & Precision: 10 isolated thin-film resistors with 1% tolerance and ±50ppm/°C TCR ensure minimal drift.
