GQCA028452GGT

GQCA028452GGT Description

The GQCA028452GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package features 12 isolated resistors, each with a 84.5K Ohm resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the 1W total power rating (0.1W per resistor) supports demanding circuits. With a maximum voltage rating of 100V and thin-film technology, this network offers low noise and high accuracy, making it ideal for isolated signal conditioning (ISOL) applications.

GQCA028452GGT Features

• Precision Thin Film: Delivers ±50ppm/°C stability and 2% tolerance for critical analog/digital circuits.
• Robust Construction: Ceramic substrate ensures thermal durability, with a 125°C max operating temperature.
• High-Density Design: 24-pin QSOP (8.66mm x 6.02mm x 1.47mm) saves PCB space while providing 12 isolated resistors.
• Reliable Termination: Gull-wing leads with 0.64mm pitch facilitate secure soldering and automated assembly.
• Derated Power Handling: 0.1W per resistor (1W total) at 70°C–125°C ensures longevity in high-temperature environments.

GQCA028452GGT Applications

• Industrial Controls: Isolated feedback networks in PLCs and motor drivers.
• Test & Measurement: Precision voltage dividers and calibration circuits.
• Medical Electronics: Signal isolation in patient monitoring equipment.
• Automotive (Non-Automotive Rated): Sensor interfaces where EU RoHS non-compliance is acceptable.
• Telecom Infrastructure: Line termination and impedance matching in RF modules.

Conclusion of GQCA028452GGT

The GQCA028452GGT excels in precision, thermal resilience, and space efficiency, distinguishing it from generic resistor arrays. Its isolated thin-film design is optimal for noise-sensitive, high-temperature environments, though it is not RoHS-compliant or automotive-rated. Engineers will value its repeatable accuracy in industrial, medical, and telecom systems where signal integrity is paramount. Packaged in tubes for ESD protection, it suits both prototyping and volume production.
