GQCA0254R9GFT Description

The GQCA0254R9GFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated resistors, each with a 54.9Ω resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior thermal stability and mechanical durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a 70°C to 125°C temperature range. The gull-wing termination ensures secure surface-mount (SMD) assembly, while its compact dimensions (8.66mm × 6.02mm × 1.47mm) make it ideal for space-constrained designs.
