GQCA033742BBT Description

The GQCA033742BBT 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 integrates 12 isolated resistors, each with a 37.4KΩ resistance value and an ultra-tight tolerance of 0.1%. Encased in a ceramic package, it offers superior thermal stability and reliability, with a temperature coefficient of ±25ppm/°C and a maximum operating temperature of 125°C. The gull-wing termination ensures secure surface-mount (SMD) attachment, while the 1W total power rating (0.1W per resistor) makes it suitable for power-sensitive designs. Its 100V maximum voltage rating and isolated circuit designator (ISOL) enhance its versatility in high-voltage and noise-sensitive environments.
