GQCA0178R7JGT Description

The GQCA0178R7JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 24-pin QSOP package features 12 isolated resistors, each with a 78.7Ω resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division in compact circuit designs. Encased in a ceramic substrate, the network offers superior thermal conductivity and mechanical durability, making it suitable for harsh environments. With a ±100ppm/°C temperature coefficient and a 1W total power rating, it maintains consistent performance across a wide temperature range (70°C to 125°C). The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating ensures compatibility with high-voltage applications.
