GS4A011403FT

GS4A011403FT Description

The GS4A011403FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 140KΩ resistance and a tight ±1% tolerance. The device operates within a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, ensuring reliability in demanding environments. Its SOIC (SOIC-C Series) ceramic case offers superior thermal stability and mechanical robustness, while the gull-wing termination facilitates easy surface-mount assembly. With a ±100ppm/°C temperature coefficient and 100V maximum voltage rating, this network is engineered for stability under varying electrical and thermal conditions.

GS4A011403FT Features

• High Precision: ±1% absolute tolerance ensures consistent performance.
• Robust Construction: Ceramic substrate enhances thermal dissipation and durability.
• Isolated Resistors: Four independent 140KΩ resistors (0.1W each, 0.4W total) for flexible circuit design.
• Wide Operating Range: -70°C to +125°C, suitable for industrial and automotive-adjacent applications.
• Low TCR: ±100ppm/°C minimizes resistance drift across temperatures.
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for compatibility with standard SOIC PCB layouts.
• Non-Automotive PPAP: Ideal for prototyping and non-automotive industrial use.

GS4A011403FT Applications

This resistor network excels in precision analog circuits, signal conditioning, and voltage division tasks. Its isolated design makes it suitable for:

• Isolation amplifiers and sensor interfaces where signal integrity is critical.
• Medical instrumentation requiring stable, high-impedance networks.
• Industrial control systems exposed to wide temperature fluctuations.
• Test and measurement equipment demanding low TCR and tight tolerances.
  While not PPAP-qualified for automotive use, it is a cost-effective choice for laboratory, telecom, and aerospace applications where ceramic reliability is prioritized.

Conclusion of GS4A011403FT

The GS4A011403FT stands out for its ceramic-based isolation, precision tolerances, and thermal resilience, offering a balance of performance and durability.
