GS4A031183JT

GS4A031183JT Description

The GS4A031183JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-pin narrow SOIC device features four isolated thin-film resistors, each rated at 118KΩ with a ±5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal resistance drift across its operating range. The SOIC-C series construction offers a compact 4.9mm × 5.99mm footprint with a 1.45mm profile, making it suitable for space-constrained PCB designs. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it operates reliably in environments up to 125°C, with derated performance from 70°C to 125°C.

GS4A031183JT Features

• Isolated Resistors: Four independent 118KΩ resistors with 5% tolerance, eliminating crosstalk in signal conditioning circuits.
• Stable Thin-Film Technology: Delivers ±25ppm/°C thermal stability, outperforming carbon-based networks in precision applications.
• Robust Ceramic Package: SOIC-C case style ensures mechanical durability and superior heat dissipation.
• Surface-Mount Gull Wing Terminals: 1.27mm pitch for compatibility with automated assembly processes.
• Wide Temperature Range: Operates from -55°C to +125°C (derated above 70°C), ideal for industrial and automotive-grade designs (though not PPAP/automotive-certified).
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.

GS4A031183JT Applications

This resistor network excels in:

• Analog Signal Isolation: Isolated elements prevent interference in sensor interfaces or ADC/DAC circuits.
• Voltage Division: Precision dividers in measurement equipment, leveraging low TCR and tight tolerance.
• Industrial Controls: Harsh-environment systems (e.g., PLCs, motor drives) benefit from ceramic packaging and high-temperature resilience.
• Legacy Electronics: Non-RoHS compliance supports military/aerospace repairs or niche industrial upgrades.

Conclusion of GS4A031183JT

The GS4A031183JT combines precision, isolation, and ruggedness in a compact SOIC format, addressing challenges in noise-sensitive or thermally demanding designs. While not automotive-qualified, its thin-film stability and ceramic construction make it a superior alternative to standard networks in professional electronics. Engineers should evaluate its non-RoHS status for compliance but can leverage its low TCR and derating flexibility for critical analog applications.
