GS4A013401FT

GS4A013401FT Description

The GS4A013401FT from TT Electronics/IRC is a high-performance 4-resistor isolated network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for precision applications requiring stable thin-film resistance. With a 3.4KΩ resistance per element and a tight ±1% tolerance, this network ensures reliable signal conditioning, voltage division, or impedance matching. The isolated circuit design (ISOL) allows independent resistor operation, eliminating crosstalk. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it operates across a wide temperature range (-70°C to +125°C) with a low ±100ppm/°C TCR, ensuring minimal drift in harsh environments. The gull-wing termination and surface-mount (SMD) SOIC package facilitate automated PCB assembly.

GS4A013401FT Features

• Ceramic substrate for superior thermal stability and durability.
• Thin-film technology delivers high precision and low noise.
• Isolated resistors (4x 3.4KΩ) for independent circuit integration.
• 1% absolute tolerance and ±100ppm/°C TCR for consistent performance.
• 125°C maximum operating temperature with derated power up to 70°C.
• Compact SOIC-8 footprint (4.9mm x 5.99mm x 1.45mm) with ±0.1mm dimensional tolerances.
• 100V voltage rating and 0.4W total power dissipation.
• Non-automotive (PPAP: No) and EU RoHS non-compliant—verify for regulatory needs.

GS4A013401FT Applications

Ideal for precision analog circuits, medical instrumentation, and industrial control systems where isolation and stability are critical. Suitable for:

• Voltage dividers in sensor interfaces.
• Feedback networks for op-amps or ADCs.
• Impedance matching in communication modules.
• High-reliability systems requiring low TCR (e.g., aerospace test equipment).
• Power supply balancing in multi-channel designs.

Conclusion of GS4A013401FT

The GS4A013401FT excels in demanding applications due to its ceramic construction, isolated thin-film resistors, and tight electrical tolerances. While not RoHS-compliant, its thermal resilience and precision make it a robust choice for industrial and instrumentation designs. Engineers should evaluate alternative models for automotive or RoHS-mandated projects.
