GS4B023920FFT

GS4B023920FFT Description

The GS4B023920FFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed with thin-film technology on a ceramic substrate, it delivers precision resistance values of 392Ω with a tight ±1% absolute tolerance and ±1% ratio tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC-C series construction features gull-wing terminations for reliable surface-mount (SMD) assembly, with a compact footprint of 4.9mm (L) × 5.99mm (D) × 1.45mm (H) and a 1.27mm terminal pitch. Rated for 0.4W total power (0.05W per resistor) and 100V maximum voltage, this network is ideal for precision analog and digital circuits requiring matched resistance values.
