GS4A024872FFT

GS4A024872FFT Description

The GS4A024872FFT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding analog and signal conditioning applications. Featuring 48.7KΩ thin-film resistors with a tight ±1% absolute tolerance and ±1% ratio tolerance, this ceramic-based network ensures stable performance across a wide temperature range (70°C to 125°C). Its ±50ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for precision circuits requiring minimal drift. The SOIC-C series construction offers robust surface-mount compatibility, with a compact footprint (4.9mm × 5.99mm × 1.45mm) and gull-wing termination for reliable PCB integration.

GS4A024872FFT Features

• Isolated Resistor Network: Four independent 48.7KΩ resistors with 1% tolerance, ideal for differential signal processing.
• High Stability: Thin-film technology and ±50ppm/°C TCR ensure minimal resistance drift under thermal stress.
• Robust Packaging: Ceramic SOIC case enhances thermal dissipation and mechanical durability.
• Precision Ratios: Matched ±1% ratio tolerance critical for voltage dividers and feedback networks.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-adjacent environments (non-automotive PPAP).
• Surface-Mount Ready: 1.27mm terminal pitch and 0.1W per resistor (0.4W total) optimize space-constrained designs.

GS4A024872FFT Applications

• Analog Signal Conditioning: Precision dividers in sensor interfaces (e.g., strain gauges, RTDs).
• Medical Electronics: Isolation networks for patient monitoring equipment.
• Test & Measurement: Calibration circuits requiring stable resistance ratios.
• Industrial Controls: Feedback loops in PLCs and motor drivers.
• Communications: Impedance matching in RF front-end modules.

Conclusion of GS4A024872FFT

The GS4A024872FFT excels in applications demanding high accuracy, thermal stability, and compact form factors. Its ceramic construction, isolated design, and tight tolerances distinguish it from polymer-based networks, making it a preferred choice for precision analog systems. While not PPAP-qualified for automotive use, it is well-suited for industrial, medical, and instrumentation markets where reliability and performance are critical. Engineers will benefit from its low drift, robust packaging, and ease of integration in surface-mount assemblies.
