GS4B032800GFT Description

The GS4B032800GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, this bussed (BUS) network integrates 7 thin-film resistors, each with a 280Ω resistance value and a tight ±2% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The device offers a power rating of 0.4W (0.05W per resistor) and supports 100V maximum voltage, making it suitable for demanding circuits. With gull-wing termination and surface-mount (SMD) compatibility, it excels in space-constrained PCB designs.
