GS4B034121JCT Description

The GS4B034121JCT from TT Electronics/IRC is a high-performance 7-resistor thin film network designed for precision applications. Encased in a ceramic SOIC-8 package, it features a 4.12KΩ resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Rated for 0.4W total power dissipation (0.05W per resistor) and 100V maximum voltage, this surface-mount device (SMD) is ideal for compact, high-density PCB designs. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable soldering, while the ceramic substrate enhances thermal and mechanical durability.
