GQCA023481GT

GQCA023481GT Description

The GQCA023481GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance and thermal performance. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 3.48KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in critical circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of -70°C to +125°C. With a maximum voltage rating of 100V and a power rating of 1W (0.1W per resistor), this network is engineered for demanding environments.

GQCA023481GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Configuration (ISOL): Each of the 12 resistors operates independently, reducing crosstalk in multi-channel systems.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical durability compared to plastic alternatives.
• Wide Temperature Range: Derated power operation up to 125°C suits industrial and automotive-adjacent applications.
• QSOP-24 Gull Wing Design: Facilitates automated PCB assembly with a 0.64mm terminal pitch and compact footprint (8.66mm × 6.02mm × 1.47mm).
• Non-Compliant with EU RoHS: Note for applications exempt from RoHS restrictions.

GQCA023481GT Applications

This resistor network excels in:

• Signal Conditioning Circuits: Precision voltage dividers or feedback networks in instrumentation.
• Isolation Interfaces: Isolated signal paths in medical devices or industrial control systems.
• High-Temperature Environments: Oil/gas sensing, power management, or aerospace subsystems where thermal stability is critical.
• Legacy or Non-RoHS Systems: Suitable for repairs or designs not requiring RoHS compliance.

Conclusion of GQCA023481GT

The GQCA023481GT stands out for its combination of precision, isolation, and ruggedness, making it ideal for engineers prioritizing reliability in harsh conditions. While not automotive-grade or PPAP-qualified, its ceramic construction, thin-film accuracy, and wide temperature range offer a compelling alternative for industrial, medical, and high-reliability consumer electronics. Its non-RoHS status may limit use in regulated markets but provides flexibility for niche applications. For designs demanding stable, isolated resistances in a compact SMD format, this network delivers exceptional performance.
