GQ0A0142R2DCT

GQ0A0142R2DCT Description

The GQ0A0142R2DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 20-pin QSOP (Quarter-Small Outline Package) device integrates 10 isolated resistors, each with a 42.2 Ω resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case 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 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for robustness in precision analog and mixed-signal systems.
