GS4A031500GFT Description

The GS4A031500GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 150Ω resistance and a tight ±2% absolute tolerance (±1% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers robust surface-mount compatibility, while the ceramic case enhances thermal and mechanical reliability. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it balances power handling with compactness.

GS4A031500GFT Features

• Isolated Resistors: Four independent 150Ω resistors prevent crosstalk, ideal for signal isolation.
• Precision Stability: ±25ppm/°C TCR and ±2% tolerance ensure consistent performance under thermal stress.
• Robust Construction: Ceramic substrate and thin-film technology provide durability and low noise.
• High-Density Packaging: SOIC-8 footprint saves board space without compromising power dissipation (0.4W total).
• Wide Voltage Range: Supports up to 100V, suitable for industrial and automotive-grade circuits (though not PPAP/automotive-certified).
• Strict Dimensional Tolerances: Tight height (±0.1mm) and depth (±0.2mm) tolerances facilitate automated assembly.

GS4A031500GFT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers or feedback networks in op-amp circuits.
