GQ0A013570CBT Description

The GQ0A013570CBT 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 features 10 isolated resistors, each with a 357 Ω resistance value and an ultra-tight ±0.25% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability, with a ±100 ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 0.1W (1/10) power rating per resistor and 1W total power rating make it suitable for precision analog and digital circuits.

GQ0A013570CBT Features
