GQCA0166R5GGT Description

The GQCA0166R5GGT 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 66.5Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The device operates over a wide temperature range of 70°C to 125°C with a derated power capability, making it suitable for environments with thermal fluctuations. Its ceramic case style and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a ±100ppm/°C temperature coefficient and a maximum voltage rating of 100V, this network excels in precision analog and digital systems.

GQCA0166R5GGT Features

• Thin-film technology: Delivers superior stability, low noise, and high accuracy.
• Isolated circuit design (ISOL): Ensures independent resistor performance, reducing crosstalk.
• High power handling: 1W total power (0.1W per resistor) for distributed load applications.
• Compact QSOP package: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained designs.
• Wide operating range: -55°C to +125°C (full power up to 70°C, derated beyond).
• Gull-wing leads: Facilitates automated SMT assembly and reliable solder joints.
• Non-RoHS compliant: Suitable for legacy or specialized industrial applications.
