GQCA011540DCT

GQCA011540DCT Description

The GQCA011540DCT 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 154 Ω resistance value and an exceptional ±0.5% tolerance. Encased in a ceramic package, it ensures superior thermal stability and durability in harsh environments. With a ±100ppm/°C temperature coefficient, 1W total power rating, and 100V maximum voltage rating, this network is engineered for reliability in precision analog and digital circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the tube packaging ensures safe handling and storage.
