GS4A024322JT

GS4A024322JT Description

The GS4A024322JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 43.2KΩ and a tolerance of ±5%. Its ±50ppm/°C temperature coefficient ensures minimal resistance drift across the operating range of 70°C to 125°C, making it suitable for environments with fluctuating temperatures. The SOIC-C series construction offers robust ceramic case durability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a maximum voltage rating of 100V and a power rating of 0.1W per resistor (0.4W total), this network balances compact dimensions (4.9mm x 5.99mm x 1.45mm) with efficient power dissipation.
