GQ0A021822CAT Description

The GQ0A021822CAT 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 package integrates 10 isolated resistors, each with a resistance value of 18.2KΩ and an exceptional tolerance of ±0.25%. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient (TCR) of ±50ppm/°C, ensuring minimal resistance drift under thermal stress. Encased in a ceramic substrate, it offers superior thermal conductivity and mechanical durability, making it ideal for harsh environments. The gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the 1W total power rating (0.1W per resistor) supports robust circuit designs.
