GQ0A034222FFT

GQ0A034222FFT Description

The GQ0A034222FFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 42.2KΩ resistance value and a tight 1% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a ±25ppm/°C temperature coefficient. The gull-wing termination ensures reliable surface-mount (SMD) connectivity, while the 0.1W power rating per resistor (1W total) makes it suitable for low-power circuits. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety in sensitive applications.
