GS4A0240R2FT

GS4A0240R2FT Description

The GS4A0240R2FT from TT Electronics/IRC is a high-precision 4-resistor network in an 8-pin narrow SOIC package, designed for isolated circuit applications (ISOL). Built with ceramic substrate and thin-film technology, it delivers stable performance with a 40.2Ω resistance per element, ±1% tolerance, and a low ±50ppm/°C temperature coefficient. Rated for 0.1W power dissipation per resistor (0.4W total), it operates across a wide temperature range of 70°C to 125°C (derated) and withstands up to 100V maximum voltage. The gull-wing termination and surface-mount design ensure reliable PCB integration, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) suit space-constrained layouts.

GS4A0240R2FT Features

• Isolated Resistor Network: Four independent resistors in an SOIC-C series package, ideal for signal isolation.
• High Precision: ±1% tolerance and ±50ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Ceramic case enhances thermal stability and durability.
• Surface-Mount Ready: Gull-wing leads and 1.27mm pitch simplify automated assembly.
• Wide Operating Range: -55°C to +125°C (full range) with derated power up to 125°C.
• Low-Noise Performance: Thin-film technology reduces parasitic effects, suitable for analog/digital interfaces.

GS4A0240R2FT Applications

• Industrial Electronics: Precision voltage dividers, feedback networks in control systems.
• Telecommunications: Impedance matching and termination in high-frequency PCBs.
• Medical Devices: Signal conditioning circuits requiring stable resistance under thermal stress.
• Automotive (Non-Automotive Rated): Sensor interfaces or infotainment systems (note: not PPAP/automotive certified).
• Test & Measurement Equipment: Calibration circuits where tolerance and TCR are critical.

Conclusion of GS4A0240R2FT

The GS4A0240R2FT excels in precision and isolation, offering repeatable performance in demanding environments. Its ceramic substrate, thin-film resistors, and compact SOIC package make it a superior choice over bulkier or less stable alternatives (e.g., thick-film networks). While not RoHS-compliant, it remains a reliable solution for industrial and telecom applications where accuracy and thermal resilience are paramount. Engineers should verify compatibility for high-voltage or automotive use due to its unconfirmed status and lack of PPAP certification.
