GQ0A031272GT

GQ0A031272GT Description

The GQ0A031272GT 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 (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 12.7KΩ resistance and a tight 2% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a power rating of 0.1W per resistor (1W total). The ±25ppm/°C temperature coefficient ensures minimal resistance drift across its operating range of -70°C to +125°C, making it suitable for harsh environments. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating enhances reliability in high-voltage circuits.
