GS4A023902GFT

GS4A023902GFT Description

The GS4A023902GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 39 kΩ resistance and a tight ±2% absolute tolerance (±1% ratio tolerance). Its SOIC-C series construction ensures robust performance in demanding environments, with a ±50 ppm/°C temperature coefficient for stable operation across a 70°C to 125°C derated power range. The 0.1W (1/10W) power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for low-power, high-voltage circuits. Encased in a rectangular ceramic package, it offers superior thermal and mechanical stability compared to polymer-based alternatives.

GS4A023902GFT Features

• Isolated Elements: Four independent resistors prevent crosstalk, ideal for signal isolation.
• Precision Thin Film: Delivers ±2% tolerance and ±50 ppm/°C TCR for consistent performance.
• Robust Construction: Ceramic case enhances durability and heat dissipation vs. plastic packages.
• Surface-Mount Design: Gull-wing terminals with 1.27mm pitch enable compact PCB layouts.
• Wide Temp Range: Operates up to 125°C, derated from 70°C, suited for industrial environments.
• Non-Automotive: Compliant with EAR99 ECCN but not PPAP or automotive-grade.

GS4A023902GFT Applications

• Signal Conditioning: Isolated resistor networks in ADC/DAC circuits for precision voltage division.
• Medical Devices: Stable performance in patient monitoring equipment due to low drift.
• Industrial Controls: Reliable operation in PLC modules and sensor interfaces.
• Test & Measurement: High-accuracy calibration tools benefiting from tight ratio tolerances.
• Power Management: Voltage reference networks in low-power DC/DC converters.

Conclusion of GS4A023902GFT

The GS4A023902GFT excels in applications requiring precision, isolation, and thermal stability. Its ceramic SOIC package and thin-film technology provide superior performance over standard arrays, particularly in high-temperature or high-voltage scenarios. While not automotive-grade, its low TCR and tight tolerances make it a standout choice for industrial, medical, and instrumentation designs where reliability is critical. Engineers should verify EU RoHS non-compliance for regulatory needs.
