GQCA0271R5GGT

GQCA0271R5GGT Description

The GQCA0271R5GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 24-pin QSOP package features 12 isolated resistors, each with a 71.5Ω resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and electrical stability, making it suitable for surface-mount (SMD) applications. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for high-density PCB designs where space and performance are critical.

GQCA0271R5GGT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Resistors (12x): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Wide Operating Range: -70°C to +125°C with derated power, ensuring reliability in harsh environments.
• Compact QSOP Package: 8.66mm x 6.02mm footprint with a 1.47mm profile, optimized for space-constrained designs.
• High Power Handling: 1W total (0.1W per resistor) supports demanding applications without derating.
• Gull-Wing Termination: Ensures strong solder joints and compatibility with automated assembly processes.
• Non-Automotive (PPAP No): Suitable for industrial, telecom, and instrumentation use.
