GQ0A026491DT

GQ0A026491DT Description

The GQ0A026491DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 6.49KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±50ppm/°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 precision analog and digital systems.
