GQCA022942JGT Description

The GQCA022942JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and thermal reliability. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 29.4kΩ resistance and a 5% tolerance, ensuring consistent performance in demanding circuits. Encased in a ceramic package, it offers superior thermal management and durability, with a maximum operating temperature of 125°C. The gull-wing termination facilitates secure surface-mount (SMD) assembly, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across its 70°C to 125°C derated power range. Packaged in a tube, it is ideal for automated PCB assembly processes.

GQCA022942JGT Features

• High Precision: Thin-film technology delivers stable 29.4kΩ ±5% resistance with low noise.
• Robust Construction: Ceramic case ensures excellent heat dissipation and mechanical strength.
• Wide Operating Range: Rated for 125°C with derated power up to 70°C–125°C.
• Low TCR: ±50ppm/°C minimizes resistance variation under thermal stress.
• Isolated Design: 12 resistors with 100V maximum voltage rating, suitable for signal isolation.
• SMD Compatibility: Gull-wing leads and 0.64mm pitch enable high-density PCB layouts.
• Power Handling: 0.1W per resistor (1W total) balances performance and compactness.

GQCA022942JGT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Industrial Controls: Isolated measurement systems requiring stable resistance under thermal cycling.
• Medical Electronics: Low-drift sensor interfaces and diagnostic equipment.
• Telecom Infrastructure: High-frequency signal processing where consistent impedance is critical.
• Automotive (Non-Automotive Rated): Non-safety-critical modules like infotainment or lighting control.
