GS4A031910FT

GS4A031910FT Description

The GS4A031910FT 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 191Ω resistance and a tight ±1% tolerance. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers robust surface-mount compatibility, while the ceramic construction enhances thermal and mechanical durability. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it balances power handling with compact design.
