GQ8A021473CT Description

The GQ8A021473CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 147K Ohm resistance per element with an ultra-tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability, making it ideal for high-reliability environments. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits requiring minimal drift and high accuracy.

GQ8A021473CT Features

• Precision Thin Film Technology: Delivers 0.25% tolerance and ±50ppm/°C TCR for minimal resistance drift.
• Robust Ceramic Package: QSOP case style with gull-wing terminals ensures reliable surface-mount (SMD) integration and mechanical strength.
• High Power Handling: 0.1W per resistor (0.75W total) derated up to 125°C, suitable for thermally challenging designs.
• Isolation-Centric Design: Labeled with "ISOL" circuit designator, optimized for isolated signal paths in mixed-signal systems.
• Strict Dimensional Tolerances: Tight ±0.1mm height/length and ±0.2mm depth tolerances facilitate consistent PCB assembly.
• Non-Automotive (PPAP No): Tailored for industrial, telecom, and instrumentation applications where precision outweighs automotive compliance.

GQ8A021473CT Applications

• Medical Equipment: Patient monitoring systems requiring stable, noise-resistant signal conditioning.
• Test & Measurement: High-accuracy multichannel data acquisition and calibration circuits.
• Industrial Controls: Isolated feedback networks in PLCs and motor drives.
• Telecom Infrastructure: Precision termination for high-speed data lines in base stations.
• Aerospace & Defense: Ruggedized electronics where ceramic packages outperform plastic alternatives.

Conclusion of GQ8A021473CT

The GQ8A021473CT stands out for its ceramic-encased reliability, thin-film precision, and isolation-focused design, making it a superior choice over plastic-packaged networks in harsh or precision-critical environments. While non-compliant with EU RoHS, its 0.25% tolerance and wide temperature range cater to specialized industrial and telecom applications where performance trumps regulatory constraints. Packaged in tubes for ESD-safe handling, it balances ease of assembly with high-end electrical characteristics.
