GQCA013480GGT

GQCA013480GGT Description

The GQCA013480GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 24-pin QSOP package features 12 isolated resistors, each with a 348 Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±100ppm/°C temperature coefficient guarantees minimal resistance drift across the 70°C to 125°C operating range. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for durability in compact designs.

GQCA013480GGT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): Each of the 12 resistors operates independently, reducing crosstalk in multi-channel systems.
• Ceramic QSOP Package: Enhances thermal management and mechanical strength compared to plastic alternatives.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, suited for industrial environments.
• Gull Wing Termination: Facilitates automated PCB assembly and improves solder joint reliability.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation applications where automotive compliance isn’t required.

GQCA013480GGT Applications

This resistor network excels in:

• Signal Conditioning Circuits: Precision voltage dividers or feedback networks in op-amp configurations.
• Isolation Interfaces: Buffering or impedance matching in communication modules (e.g., RS-485, CAN).
• Test & Measurement Equipment: Calibration circuits or sensor interfaces demanding low drift.
• Power Supply Control: Current sensing or feedback loops in DC-DC converters.
• Medical Electronics: Non-critical analog subsystems where stability outweighs RoHS compliance needs (EU RoHS Not Compliant).

Conclusion of GQCA013480GGT

The GQCA013480GGT stands out for its isolated thin-film resistors, ceramic robustness, and precision tolerances, making it a superior choice over generic arrays in noise-sensitive or thermally variable environments. While not suited for automotive use, its QSOP form factor and 1W power handling cater to space-constrained, high-reliability designs in industrial and telecom sectors. Engineers prioritizing long-term stability and moderate power dissipation will find this network an optimal solution for isolation-critical applications.
