GQCA021403JFT Description

The GQCA021403JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 24-pin QSOP package integrates 12 isolated resistors, each rated at 140K Ohm with 5% tolerance, delivering a total power rating of 1W (0.1W per resistor). The device operates over a wide temperature range of 70°C to 125°C, with a ±50ppm/°C temperature coefficient, ensuring reliable performance in thermally demanding environments. Its ceramic case style and gull-wing termination enable robust surface-mount (SMD) assembly, while the QSOP package (8.66mm x 6.02mm x 1.47mm) offers compactness for space-constrained designs.

GQCA021403JFT Features

• Precision Thin Film Technology: Delivers low noise and high stability, ideal for signal conditioning and analog circuits.
• Isolated Resistor Network (ISOL): Each of the 12 resistors is electrically isolated, providing flexibility in circuit design.
• High Power Handling: 1W total power dissipation (0.1W per resistor) with 100V maximum voltage rating.
