GQCB0178R7JDT Description

The GQCB0178R7JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package integrates 23 resistors with a 78.7Ω resistance value and a 5% tolerance, offering a ±100ppm/°C temperature coefficient for stable operation across a 70°C to 125°C derated power range. Encased in a ceramic substrate, it ensures durability and thermal stability, with a 1W total power rating (0.05W per resistor). The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating makes it suitable for robust circuit protection.
