GQCA024642JFT Description

The GQCA024642JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 46.4kΩ resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division in compact circuits. Encased in a ceramic package, it offers superior thermal conductivity and mechanical durability, with a maximum operating temperature of 125°C. The gull-wing termination facilitates easy surface-mount (SMD) assembly, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across its 70°C to 125°C derated power range.

GQCA024642JFT Features

• High-Density Integration: 12 resistors in a 24-pin QSOP (6.02mm x 8.66mm footprint), ideal for space-constrained designs.
• Precision Thin-Film Technology: Delivers ±5% tolerance and ±50ppm/°C TCR for stable performance in varying thermal conditions.
• Robust Construction: Ceramic case enhances heat dissipation and withstands harsh environments.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch ensure compatibility with automated PCB assembly.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation applications.

GQCA024642JFT Applications

This resistor network excels in:

• Analog Signal Processing: Precision voltage dividers, feedback networks in op-amp circuits.
• Industrial Controls: PLCs, sensor interfaces, and motor drivers requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits, load banks, and data acquisition systems.
• Medical Electronics: Isolated signal paths in patient monitoring devices.
• Automotive Alternatives: While not PPAP/Automotive-rated, it suits non-safety-critical automotive subsystems like infotainment.
