GQ0A034640FAT Description

The GQ0A034640FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated resistors, each with a 464 Ω resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, making it suitable for environments with thermal stress. Its ceramic case and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a ±25ppm/°C temperature coefficient, it offers excellent stability under varying thermal conditions. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating further enhance its versatility in high-reliability designs.
