GS4A031242JFT Description

The GS4A031242JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features a 12.4KΩ resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance in matched circuits. Its thin-film technology and ±25ppm/°C temperature coefficient provide excellent thermal stability, while the ceramic case enhances durability and heat dissipation. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it operates reliably across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C.

GS4A031242JFT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• Precision & Stability: ±25ppm/°C TCR and ±5% tolerance ensure minimal drift in harsh environments.
• Robust Construction: Ceramic SOIC package offers superior thermal and mechanical resilience.
• Surface-Mount Compatibility: Gull-wing termination and 1.27mm pitch simplify PCB assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Wide Voltage Range: Supports up to 100V, suitable for industrial and automotive-grade designs (though not PPAP/automotive-certified).

GS4A031242JFT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring matched resistances.
• Industrial Control Systems: PLCs, motor drives, and power supplies where thermal stability is critical.
