GQCA031912GFT Description

The GQCA031912GFT 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 24-pin QSOP package features 12 isolated resistors, each with a 19.1KΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across the -70°C to +125°C operating range. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for isolation and signal conditioning in industrial and instrumentation systems.

GQCA031912GFT Features

• Precision Thin Film Technology: Delivers stable resistance with low noise and high accuracy (±25ppm/°C).
• Isolated Resistor Network (ISOL): 12 independent resistors in a compact QSOP package (8.66mm x 6.02mm x 1.47mm), suitable for high-density PCBs.
