GQ8A024220CAT Description

The GQ8A024220CAT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Housed in a 16-pin QSOP ceramic package, it offers 422Ω resistance per element with an exceptional ±0.25% tolerance and a ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The isolated (ISOL) circuit design provides independent resistors, making it ideal for precision signal conditioning. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances performance and reliability in compact designs.
