GS4A034871JGT

GS4A034871JGT Description

The GS4A034871JGT from TT Electronics/IRC is a high-performance 4-resistor network designed for precision applications requiring stable resistance values and tight tolerances. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, this isolated-element network features a 4.87KΩ resistance per resistor with an absolute tolerance of ±5% and a ratio tolerance of ±2%. Its thin-film technology ensures low noise and high reliability, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across a wide operating range of -70°C to +125°C. Rated for 0.1W (1/10W) power dissipation per resistor (0.4W total), it supports 100V maximum voltage and is optimized for surface-mount assembly with gull-wing terminations.

GS4A034871JGT Features

• Ceramic SOIC Package: Robust construction with 4.9mm length, 5.99mm depth, and 1.45mm height (±0.1mm tolerances), ensuring mechanical durability.
• Isolated Resistors: Independent elements (no shared substrate) for flexible circuit design.
• Precision Performance: ±25ppm/°C TCR and ±5% tolerance for stable operation in demanding environments.
• High-Temperature Suitability: Rated for 125°C maximum operating temperature, ideal for industrial and automotive-adjacent applications (though not PPAP/AEC-Q200 qualified).
• Thin-Film Technology: Delivers low parasitic effects and superior long-term stability vs. thick-film alternatives.

GS4A034871JGT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers in sensor interfaces (e.g., thermocouples, strain gauges).
• Analog Circuits: Feedback networks for op-amps or ADCs requiring tight ratio matching (±2%).
• Industrial Controls: PLCs, motor drives, and power supplies where temperature stability is critical.
• Test & Measurement Equipment: Calibration circuits due to low drift and high accuracy.
• Non-Automotive High-Reliability Systems: Medical devices or aerospace subsystems (note: non-RoHS).

Conclusion of GS4A034871JGT

The GS4A034871JGT stands out for its ceramic-packaged isolation, thin-film precision, and wide thermal range, making it a robust choice for engineers prioritizing stability in harsh conditions. While not suited for automotive or RoHS-compliant designs, its low TCR, tight ratio tolerance, and high voltage rating make it ideal for industrial, instrumentation, and precision analog applications where competing networks may falter. Its SOIC footprint ensures compatibility with standard SMT processes, reducing assembly complexity.
