GS4A032700CT

GS4A032700CT Description

The GS4A032700CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 270Ω resistance and an exceptional ±0.25% tolerance. The device operates over a wide temperature range of 70°C to 125°C with a ±25ppm/°C temperature coefficient, ensuring stability in fluctuating thermal conditions. Encased in a rectangular ceramic SOIC package, it offers 0.1W (1/10) power rating per resistor (0.4W total) and supports 100V maximum voltage. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 1.27mm terminal pitch ensures compatibility with standard layouts.

GS4A032700CT Features

• Precision Performance: ±0.25% absolute tolerance and ±25ppm/°C TCR for high-accuracy signal conditioning.
• Robust Construction: Ceramic case provides superior thermal and mechanical stability.
• Isolated Resistors: Four independent 270Ω resistors enable flexible circuit design.
• Surface-Mount Ready: Gull-wing terminals and 1.27mm pitch for efficient assembly.
• Wide Operating Range: Rated for -55°C to +125°C (derated power up to 125°C).
• Low Power Dissipation: 0.1W per resistor, ideal for low-energy applications.

GS4A032700CT Applications

This resistor network excels in precision analog and digital circuits, including:

• Voltage dividers and feedback networks in op-amp circuits.
• Sensor signal conditioning (e.g., thermocouples, strain gauges).
• Medical instrumentation requiring stable, low-drift resistance.
• Industrial control systems where isolation and accuracy are critical.
• Automotive test equipment (though not PPAP/AEC-Q200 qualified).

Conclusion of GS4A032700CT

The GS4A032700CT stands out for its ceramic-based isolation, tight tolerances, and thin-film technology, making it a reliable choice for precision applications. While not automotive-grade, its thermal resilience and low TCR suit industrial, medical, and test environments. Engineers will appreciate its balance of performance, durability, and ease of integration, particularly in designs demanding stable resistance under thermal stress. For non-PPAP projects requiring high accuracy, this network offers a cost-effective solution.
