GQCA033742BT

GQCA033742BT Description

The GQCA033742BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated resistors, each with a 37.4KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±25ppm/°C temperature coefficient guarantees stable performance across a wide operating range (70°C to 125°C). With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is engineered for reliability in precision analog and digital systems.
