GS4B014302DCT Description

The GS4B014302DCT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for BUS circuit applications. Housed in an 8-pin SOIC ceramic package, it offers a 43K Ohm resistance with an ultra-tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C operating range. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this surface-mount device (SMD) is engineered for reliability in demanding environments. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.
