GS4A024990FAT

GS4A024990FAT Description

The GS4A024990FAT 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 499Ω resistance and a tight ±1% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers reliable surface-mount compatibility, while the 0.1W power rating per resistor (0.4W total) balances compactness with robust power handling.

GS4A024990FAT Features

• Isolated Resistors: Four independent 499Ω resistors with ±0.05% ratio tolerance, ideal for differential signaling or precision voltage division.
• High-Temperature Stability: Ceramic case and thin-film technology ensure minimal drift even at 125°C maximum operating temperature.
• Precision Engineering: Tight tolerances (±1% absolute, ±50ppm/°C) suit critical analog/digital circuits.
• Robust Construction: 100V maximum voltage rating and 0.4W total power dissipation in a compact SOIC footprint.
• Automation-Friendly: 1.27mm terminal pitch and surface-mount design streamline PCB assembly.

GS4A024990FAT Applications

• Industrial Electronics: Signal conditioning, feedback networks, and sensor interfaces requiring low TCR and high isolation.
• Medical Devices: Precision instrumentation where stable resistance ratios are critical (e.g., ECG amplifiers).
• Telecom Infrastructure: Impedance matching in high-frequency RF modules due to low parasitic effects.
• Test & Measurement: Calibration circuits benefiting from ±0.05% ratio tolerance.

Conclusion of GS4A024990FAT

The GS4A024990FAT excels in applications demanding precision, thermal stability, and compactness. Its isolated thin-film resistors, ceramic construction, and tight tolerances make it superior to generic arrays in harsh environments. While not RoHS-compliant, its performance-centric design justifies use in aerospace, medical, and industrial systems where reliability outweighs regulatory constraints. A top choice for engineers prioritizing accuracy and durability in space-constrained designs.
