GQCA011820DCT

GQCA011820DCT Description

The GQCA011820DCT 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 182Ω resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±100ppm/°C temperature coefficient guarantees stable performance across a wide operating range of -70°C to +125°C. With a 0.1W power rating per resistor (1W total) and a 100V maximum voltage rating, this network is engineered for precision signal conditioning, voltage division, and impedance matching in compact PCB designs.
