GQ0A031470JT

GQ0A031470JT Description

The GQ0A031470JT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 20-pin QSOP package features 10 isolated resistors, each with a 147Ω resistance (5% tolerance) and a ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range (70°C to 125°C). Encased in a ceramic substrate, the network delivers 0.1W (1/10W) power dissipation per resistor (1W total), with a 100V maximum voltage rating, making it suitable for demanding environments. Its gull-wing termination and surface-mount design (6.02mm x 8.66mm footprint) facilitate compact PCB integration.
