GS4A021471FT

GS4A021471FT Description

The GS4A021471FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 1.47 kΩ resistance and a tight ±1% tolerance. With a ±50 ppm/°C temperature coefficient, it ensures stable performance across a wide temperature range (70°C to 125°C). The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) offers a compact footprint, making it ideal for space-constrained designs. Rated for 0.1 W per resistor (0.4 W total) and 100 V maximum voltage, it combines reliability with high power density. The gull-wing termination ensures secure surface mounting, while the ceramic case enhances thermal and mechanical durability.
