GS4A021101FT

GS4A021101FT Description

The GS4A021101FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. Housed in an 8-pin narrow SOIC package, this 4-resistor network features isolated elements (ISOL) with a 1.1KΩ resistance and a tight ±1% tolerance, ensuring consistent performance in demanding circuits. Its thin-film technology and ±50ppm/°C temperature coefficient provide excellent stability across a wide operating temperature range of -55°C to +125°C, derated up to 125°C. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this component is engineered for durability in surface-mount applications.

GS4A021101FT Features

• Ceramic Case & SOIC Package: Robust rectangular ceramic construction (4.9mm x 5.99mm x 1.45mm) with gull-wing terminals for secure SMT soldering.
• Precision Performance: 1% absolute tolerance and ±50ppm/°C TCR for minimal drift in varying environments.
• Isolated Design: Independent resistors reduce crosstalk, ideal for signal conditioning or voltage division.
• High-Temperature Resilience: Operates up to 125°C with derated power, suited for industrial or automotive-adjacent systems (non-Automotive PPAP).
• Thin-Film Technology: Delivers low noise and high accuracy compared to thick-film alternatives.

GS4A021101FT Applications

This resistor network excels in:

• Analog Signal Processing: Precision dividers or feedback networks in op-amp circuits.
• Industrial Controls: Stable resistance in PLCs, sensors, or power management modules.
• Test & Measurement Equipment: Calibration circuits requiring low TCR and high tolerance.
• Consumer Electronics: Compact designs needing reliable passive networks (non-RoHS compliant).

Conclusion of GS4A021101FT

The GS4A021101FT combines ceramic durability, thin-film precision, and isolated topology to outperform generic resistor arrays in critical applications. Its SOIC footprint and 1.27mm terminal pitch facilitate easy integration, while the 1.1KΩ value and 1% tolerance ensure repeatable performance. Though not RoHS-compliant, it remains a top choice for engineers prioritizing thermal stability and circuit isolation in industrial, instrumentation, and high-reliability systems.
