GQCA0245R3GGT

GQCA0245R3GGT Description

The GQCA0245R3GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a resistance value of 45.3Ω and a tight tolerance of ±2%. Encased in a robust ceramic package, it offers excellent thermal stability with a low temperature coefficient of ±50ppm/°C and operates across a wide temperature range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for demanding environments. Its gull-wing termination ensures secure surface-mount assembly, while the QSOP package (8.66mm x 6.02mm x 1.47mm) provides a compact footprint for space-constrained designs.
