GQCA031502JFT Description

The GQCA031502JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated 15KΩ resistors with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Encased in a ceramic package, it offers superior thermal stability and durability, making it suitable for demanding environments. The gull-wing termination enables secure surface-mount (SMD) assembly, while the 0.64mm terminal pitch accommodates high-density PCB layouts. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for analog signal conditioning, voltage division, and isolation circuits.
