GS4A021153FT

GS4A021153FT Description

The GS4A021153FT 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 with a 115KΩ resistance and a tight ±1% tolerance. Its ±50ppm/°C temperature coefficient ensures minimal resistance drift across the 70°C to 125°C operating range, making it suitable for environments with fluctuating temperatures. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations facilitates easy surface-mount assembly, while the ceramic case enhances durability and heat dissipation. Rated for 100V maximum voltage and 0.1W power per resistor (0.4W total), it balances compactness with reliable performance.

GS4A021153FT Features

• Isolated Circuit Design: Four independent resistors prevent cross-talk, ideal for signal isolation.
• Precision Thin-Film Technology: Delivers ±1% tolerance and low TCR (±50ppm/°C) for stable performance.
• Robust Construction: Ceramic SOIC package withstands high temperatures (up to 125°C) and mechanical stress.
• Surface-Mount Optimized: Gull-wing terminals and 1.27mm pitch ensure compatibility with automated PCB assembly.
• Derated Power Handling: Maintains functionality at 70–125°C with derated power, avoiding thermal runaway.
• Non-Automotive/Non-PPAP: Suitable for industrial and commercial (non-automotive) applications.

GS4A021153FT Applications

• Signal Conditioning: Isolated resistor networks in ADC/DAC circuits and voltage dividers.
• Medical Electronics: Precision instrumentation where low drift and reliability are critical.
• Industrial Controls: PLC modules and sensor interfaces requiring stable resistance under thermal stress.
• Test & Measurement Equipment: Calibration circuits due to high accuracy (±1%).
• Power Management: Feedback networks in DC-DC converters leveraging its 100V rating.

Conclusion of GS4A021153FT

The GS4A021153FT excels in precision, isolation, and thermal stability, distinguishing it from generic resistor arrays. Its ceramic SOIC package and thin-film technology cater to demanding applications in industrial, medical, and test systems. While not PPAP-capable or automotive-grade, its 1% tolerance, low TCR, and 125°C rating make it a superior choice for engineers prioritizing accuracy and durability in harsh environments. For designs needing compact, high-reliability resistor networks, this model offers a compelling balance of performance and manufacturability.
