GQ0A0364R9DCT Description

The GQ0A0364R9DCT 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 integrates 10 isolated resistors, each with a resistance value of 64.9Ω and a tight tolerance of ±0.5%, ensuring exceptional accuracy in circuit performance. The ceramic case construction enhances thermal stability, while the gull-wing termination facilitates reliable surface-mount assembly. With a ±25ppm/°C temperature coefficient and a derated operating range of 70°C to 125°C, this network maintains consistent performance under varying thermal conditions. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it is ideal for precision analog and digital systems.
