GS4A017502FT

GS4A017502FT Description

The GS4A017502FT 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 75 kΩ resistance and a tight ±1% tolerance. It operates within a wide temperature range of -70°C to +125°C, derated for optimal performance, and offers a ±100 ppm/°C temperature coefficient for stable operation under thermal stress. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations ensures reliable surface-mount assembly, while its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for demanding circuits.

GS4A017502FT Features

• Isolated Circuit Design: Four independent resistors (ISOL configuration) minimize crosstalk, ideal for signal isolation.
• Precision Thin Film: Delivers low noise and high stability, with a ±1% absolute tolerance.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical durability in harsh environments.
• Wide Operating Range: -70°C to +125°C with derated power, suited for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Surface-Mount Ready: SOIC package with 1.27 mm pitch for compatibility with automated PCB assembly.
• Non-RoHS: May be preferred for legacy or specialized systems requiring non-compliant materials.

GS4A017502FT Applications

• Signal Conditioning: Isolated resistor networks for op-amp feedback, voltage dividers, or DAC/ADC interfaces.
• Industrial Controls: Precision measurement systems, sensor calibration, and instrumentation where thermal stability is critical.
• Power Management: Voltage scaling or current-limiting circuits in power supplies (up to 100V).
• Legacy Electronics: Repair or replacement in non-RoHS-compliant equipment.

Conclusion of GS4A017502FT

The GS4A017502FT excels in precision, isolation, and thermal performance, distinguishing it from generic resistor arrays. Its ceramic construction, tight tolerances, and isolated design cater to high-reliability applications, though its non-automotive and non-RoHS status may limit use in regulated markets. Engineers will value its balance of stability, power handling, and compact form factor for critical analog and mixed-signal designs.
