GQ0A034220CBT Description

The GQ0A034220CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 422Ω resistance value and an exceptional ±0.25% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, making it ideal for harsh environments. With a ±25ppm/°C temperature coefficient, it ensures minimal resistance drift across its operating range of 70°C to 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating further enhance its reliability in precision circuits.
