GQ0A031782JGT Description

The GQ0A031782JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 20-pin QSOP package integrates 10 isolated resistors, each rated at 17.8KΩ with a 5% tolerance and a ±25ppm/°C temperature coefficient. Encased in a ceramic substrate, it ensures excellent thermal stability and durability in demanding environments. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, this network is ideal for circuits requiring consistent performance under thermal stress. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating makes it suitable for medium-voltage applications.
