GQCA032800GFT

GQCA032800GFT Description

The GQCA032800GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP device features 12 isolated resistors, each with a 280Ω 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) integration, while the ±25ppm/°C temperature coefficient guarantees stability across a wide 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 demanding environments. Packaged in a tube, it offers mechanical protection during handling and assembly.

GQCA032800GFT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±2% tolerance) for signal conditioning and analog circuits.
• Isolated Resistor Design (ISOL): Each of the 12 resistors operates independently, ideal for multi-channel isolation.
• Robust Ceramic Package: Enhances thermal management and durability in harsh conditions.
• Wide Temperature Range: Stable performance from -70°C to +125°C (derated up to 125°C).
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained PCBs.
• Gull-Wing Termination: Facilitates automated soldering and inspection processes.
• Non-Automotive (PPAP No): Suitable for industrial, telecom, and instrumentation applications.

GQCA032800GFT Applications

This resistor network excels in:

• Analog Signal Processing: Voltage dividers, DAC/ADC interfaces, and sensor calibration.
• Medical Equipment: Isolated measurement circuits requiring precision and stability.
• Test & Measurement Systems: High-accuracy instrumentation and feedback networks.
• Industrial Controls: PLCs, motor drives, and power supply regulation.
