GS4A031822JFT Description

The GS4A031822JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 18.2 kΩ and a ±5% absolute tolerance. The device operates within a temperature range of 70°C to 125°C, delivering a power rating of 0.1W per resistor (0.4W total). Its ±25 ppm/°C temperature coefficient ensures minimal resistance drift, making it suitable for environments with fluctuating temperatures. The SOIC-C series construction provides robust mechanical stability, with a compact footprint (4.9mm x 5.99mm x 1.45mm) and gull-wing terminations for reliable surface-mount assembly.
