GQCA011400GT

GQCA011400GT Description

The GQCA011400GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 24-pin QSOP package features 12 isolated resistors, each with a 140 Ohm resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±100ppm/°C temperature coefficient guarantees minimal resistance variation across its operating range of -70°C to +125°C. With a 0.1W power rating per resistor (1W total) and 100V maximum voltage rating, this network is engineered for signal conditioning, isolation, and voltage division in compact designs.

GQCA011400GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): 12 independent resistors prevent crosstalk, ideal for multi-channel systems.
• Robust Ceramic Package: Enhances thermal management and mechanical durability in harsh environments.
• QSOP-24 Gull Wing SMD: Space-saving footprint (8.66mm × 6.02mm × 1.47mm) with ±0.1mm dimensional tolerances.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at elevated temperatures.
• Non-Automotive, Non-PPAP: Suitable for industrial, telecom, and instrumentation applications.

GQCA011400GT Applications

• Signal Isolation & Conditioning: Isolated resistor arrays for ADC/DAC reference circuits or sensor interfaces.
• Voltage Division Networks: Precision dividers in test equipment or medical devices.
• Communication Systems: Impedance matching and termination in high-frequency RF modules.
• Industrial Controls: Robust performance in PLCs, motor drives, and power supplies.
• Aerospace & Defense: Stable operation in extreme temperatures due to ceramic construction.

Conclusion of GQCA011400GT

The GQCA011400GT excels in applications demanding high precision, thermal stability, and compact integration. Its isolated thin-film resistors, ceramic QSOP package, and wide operating range make it a superior choice over generic networks, particularly in environments where space, reliability, and signal integrity are critical. While not RoHS-compliant, its non-automotive grade suits industrial and telecom sectors. Engineers will value its repeatable performance in prototyping and production runs, backed by TT Electronics/IRC’s legacy in resistor technology.
