GQCA034532CBT Description

The GQCA034532CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP (Quad Flat Small Outline Package) device features 12 isolated resistors, each with a 45.3KΩ resistance value and an ultra-tight tolerance of ±0.25%. The network is built on a ceramic substrate, ensuring excellent thermal stability and reliability across a wide temperature range of -70°C to +125°C. With a thin-film technology foundation, it delivers a low temperature coefficient of ±25ppm/°C, minimizing resistance drift under thermal stress. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog circuits, while its gull-wing termination enables robust surface-mount (SMD) assembly. Packaged in a tube, this non-automotive (PPAP: No) component is ideal for industrial and instrumentation use.
