GS4B033900FDT Description

The GS4B033900FDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC package, designed for surface-mount applications. With a 390Ω resistance per element and a tight 1% tolerance, this network ensures reliable signal conditioning and voltage division in compact circuits. Its ceramic case and thin-film technology provide excellent thermal stability, with a low ±25ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, it suits both industrial and commercial electronics. The gull-wing termination ensures secure PCB mounting, while the SOIC package (4.9mm × 5.99mm × 1.45mm) offers space efficiency.
