GS4A014991GGT Description

The GS4A014991GGT from TT Electronics/IRC is a high-performance 4-resistor isolated network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 4.99KΩ resistance value and ±2% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±100ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for circuits requiring consistent operation across a 70°C to 125°C derated range, with a maximum operating temperature of 125°C. The SOIC package (4.9mm × 5.99mm × 1.45mm) features gull-wing terminations for secure surface mounting, adhering to a 1.27mm terminal pitch.

GS4A014991GGT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Stability: Thin-film technology and ceramic case ensure low noise and long-term reliability.
• Precision Tolerance: ±2% absolute and ratio tolerance for consistent performance in matched circuits.
• Robust Construction: 100V maximum voltage rating and wide temperature range support industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Compact & Standardized: SOIC footprint (compatible with automated assembly) and ±0.1mm length/height tolerances for precise placement.

GS4A014991GGT Applications

• Signal Conditioning: Ideal for ADC/DAC reference networks and voltage dividers in measurement systems.
• Industrial Controls: Used in PLC modules, sensor interfaces, and power management circuits due to its isolation and stability.
• Communications Equipment: Supports impedance matching and termination in RF/mixed-signal PCBs.
• Medical Devices: Suitable for low-noise analog front-ends where consistent resistance ratios are critical.
