GQCA032550BT Description

The GQCA032550BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 255Ω resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in circuit performance. Encased in a ceramic package, it offers superior thermal stability and reliability across a wide temperature range of -70°C to +125°C. With a ±25ppm/°C temperature coefficient, this network maintains consistent resistance values under varying environmental conditions. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating and 1W total power dissipation make it suitable for high-density designs.
