GQ0A031053JAT Description

The GQ0A031053JAT 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 10-resistor array features a 105K Ohm resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and 100V maximum voltage rating, making it suitable for demanding circuit environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the isolated (ISOL) circuit designator ensures individual resistor independence.
