GS4A0371R5GT

GS4A0371R5GT Description

The GS4A0371R5GT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring 71.5Ω resistance per element with a tight ±2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, this thin-film ceramic-based network ensures reliable performance across a wide temperature range (70°C to 125°C). Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog and digital circuits. The SOIC-C series construction offers robust ceramic substrate isolation, minimizing crosstalk between resistors—a critical advantage in signal integrity applications.

GS4A0371R5GT Features

• Isolated Resistor Network: Four independent thin-film resistors in a single 8-pin SOIC package, eliminating mutual interference.
• High Stability: ±25ppm/°C TCR and 2% tolerance ensure consistent performance under thermal stress.
• Robust Construction: Ceramic case with gull-wing leads for superior thermal management and mechanical durability.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint with 1.27mm terminal pitch, ideal for high-density PCB designs.
• Wide Operating Range: Rated for -55°C to +125°C, derated to 70°C to 125°C at full power.

GS4A0371R5GT Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to low TCR and tight tolerance.
• Signal Conditioning: Isolated resistors reduce noise in sensor interfaces (e.g., thermocouples, strain gauges).
• Industrial Electronics: Suitable for PLCs, motor drives, and power supplies requiring stable resistance under thermal cycling.
• Test & Measurement Equipment: Ensures accuracy in calibration circuits and instrumentation amplifiers.

Conclusion of GS4A0371R5GT

The GS4A0371R5GT stands out for its isolated design, ceramic reliability, and precision thin-film technology, making it a superior choice over polymer-based networks in high-temperature or noise-sensitive environments. Its combination of low TCR, compact form factor, and 100V rating positions it as a versatile solution for industrial, automotive (non-AECQ), and precision analog applications where stability and space efficiency are critical.
