GQCA023240JFT

GQCA023240JFT Description

The GQCA023240JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 324Ω resistance value and a 5% tolerance, ensuring reliable performance in compact circuit designs. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of -70°C to +125°C. 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 demanding environments.

GQCA023240JFT Features

• Isolated Resistor Network: 12 resistors with independent isolation (ISOL designator), reducing crosstalk in multi-channel circuits.
• Precision Thin Film Technology: Delivers ±50ppm/°C thermal stability, outperforming thick-film alternatives in temperature-sensitive applications.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm length/height), saving PCB space.
• High Power Handling: 1W total dissipation (0.1W per resistor) at 125°C derated power, suitable for power distribution circuits.
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its ceramic construction and wide temperature range make it viable for industrial and telecom applications.
• Non-RoHS Compliance: Note: Not compliant with EU RoHS, limiting use in regulated markets but offering flexibility in legacy systems.

GQCA023240JFT Applications

• Signal Isolation: Ideal for ADC/DAC reference circuits and sensor interfaces where resistor matching is critical.
• Power Supply Dividers: Used in voltage scaling networks due to its 100V rating and low TCR.
• Industrial Controls: Robust ceramic packaging suits motor drives, PLCs, and instrumentation exposed to thermal cycling.
• Telecom Hardware: Gull-wing termination ensures reliable SMT assembly in RF modules and baseband PCBs.
• Legacy Equipment Repair: Non-RoHS compliance makes it a drop-in replacement for older designs.

Conclusion of GQCA023240JFT

The GQCA023240JFT combines thin-film precision, compact QSOP packaging, and isolated resistor topology to address challenges in high-density, thermally unstable environments. While its non-RoHS status restricts use in newer designs, it excels in industrial, telecom, and legacy systems requiring stable resistance networks. Engineers will appreciate its balance of power handling, thermal performance, and space efficiency, making it a versatile choice for isolation and signal conditioning tasks. For applications demanding tighter tolerances or automotive compliance, alternative models should be evaluated.
