GS4A011872FT

GS4A011872FT Description

The GS4A011872FT 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 18.7KΩ resistance and a tight ±1% tolerance. The network operates within a temperature range of 70°C to 125°C with a derated power rating, ensuring reliability in demanding environments. Its ±100ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for stable, low-drift circuits. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations ensures easy surface-mount integration.

GS4A011872FT Features

• Isolated Circuit Design (ISOL): Prevents crosstalk, ideal for multi-channel systems.
• High Power Handling: 0.1W per resistor (0.4W total) with derating up to 125°C.
• Precision Thin-Film Technology: Delivers ±1% tolerance and low TCR (±100ppm/°C).
• Robust Construction: Ceramic case ensures thermal stability and mechanical durability.
• Surface-Mount Ready: 1.27mm terminal pitch and SOIC footprint simplify PCB assembly.
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation use.

GS4A011872FT Applications

• Signal Conditioning: Isolated resistor networks for op-amp feedback or voltage dividers.
• Medical Electronics: Stable resistance in diagnostic equipment due to low drift.
• Test & Measurement: Precision circuits requiring tight tolerance (e.g., multimeters, calibrators).
• Industrial Controls: Reliable performance in PLCs and sensor interfaces.
• Telecom Infrastructure: Signal integrity in high-frequency analog/digital hybrid systems.

Conclusion of GS4A011872FT

The GS4A011872FT excels in applications demanding precision, isolation, and thermal resilience. Its ceramic construction, thin-film technology, and SOIC compatibility offer a competitive edge over polymer-based networks. While not PPAP or RoHS compliant, it remains a cost-effective solution for non-automotive high-reliability systems. Engineers will value its balance of performance, size, and power handling in critical analog designs.
