GQCB0126R1JT

GQCB0126R1JT Description

The GQCB0126R1JT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit applications. This 24-pin QSOP package integrates 23 resistors, each with a 26.1Ω resistance value (5% tolerance) and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) applications. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in precision analog and digital circuits.

GQCB0126R1JT Features
