GS4A013902FFT

GS4A013902FFT Description

The GS4A013902FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 4-resistor isolated network features a 39KΩ resistance value with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched resistor applications. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology delivers excellent stability, with a low ±100ppm/°C temperature coefficient, making it suitable for environments with fluctuating temperatures. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it operates reliably across a -70°C to +125°C range, even at derated power.

GS4A013902FFT Features

• High Precision: ±1% tolerance and ±100ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Ceramic case and thin-film technology enhance durability and thermal performance.
• Isolated Design: Independent resistors (4-element network) reduce crosstalk in signal paths.
• Space-Efficient: SOIC package (4.9mm length) ideal for high-density PCB layouts.
