GQCA0368R1GGT

GQCA0368R1GGT Description

The GQCA0368R1GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 68.1Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across the -70°C to +125°C operating range. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (1W total), this network is ideal for analog signal conditioning, isolation, and precision voltage division.
