GS4B031802FFT

GS4B031802FFT Description

The GS4B031802FFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features 18KΩ thin-film resistors with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in demanding circuits. The ceramic-based construction provides excellent thermal stability, with a ±25ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. Rated for 0.05W (1/20) per resistor and 0.4W total power dissipation, it operates reliably within a 70°C to 125°C derated range, with a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4B031802FFT Features

• Precision Network: 7 bussed resistors, 18KΩ ±1% tolerance, ideal for matched impedance applications.
• Stable Performance: ±25ppm/°C TCR ensures minimal resistance drift across temperature variations.
• Robust Construction: Ceramic case (SOIC package) enhances durability and heat dissipation.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint with 1.27mm terminal pitch.
• Wide Operating Range: -55°C to +125°C (full range), derated to 70°C to 125°C for optimal power handling.
• High Voltage Tolerance: Supports up to 100V, suitable for industrial and automotive-grade designs (though non-automotive PPAP).

GS4B031802FFT Applications

• Voltage Divider Networks: Precision dividers in sensor interfaces or ADC circuits.
• Signal Conditioning: Matched impedance paths in communication systems (e.g., CAN bus).
• Industrial Controls: Stable resistor networks in PLCs or power management modules.
• Test & Measurement Equipment: Calibration circuits requiring low TCR and tight tolerance.
• Aerospace & Defense: Reliable performance in harsh environments (non-RoHS compliant).

Conclusion of GS4B031802FFT

The GS4B031802FFT excels in precision, thermal stability, and compactness, distinguishing it from generic resistor arrays. Its ceramic SOIC package and thin-film technology cater to high-reliability applications, though it lacks RoHS compliance. Ideal for engineers prioritizing matched resistance, low drift, and space savings, it is a robust choice for industrial, instrumentation, and embedded systems where consistent performance is critical.
