GQCA031581CBT Description

The GQCA031581CBT from TT Electronics/IRC is a high-precision, thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter-Small Outline Package) device features 12 isolated resistors, each with a 1.58KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Encased in a robust ceramic package, it offers superior thermal stability and mechanical durability, with a maximum operating temperature of 125°C and a ±25ppm/°C temperature coefficient. The gull-wing termination enables reliable surface-mount assembly, while the 0.1W power rating per resistor (1W total) supports low-power applications.
