GS7B0251R1JFT Description

The GS7B0251R1JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 14-pin narrow SOIC package integrates 13 bussed resistors, each with a 51.1Ω resistance and a ±5% absolute tolerance, ensuring consistent performance across a wide temperature range of 70°C to 125°C. The device leverages thin-film technology for superior stability and a low temperature coefficient of ±50ppm/°C, making it ideal for environments requiring minimal resistance drift. With a power rating of 0.7W (0.05W per resistor) and a maximum voltage rating of 100V, it balances power handling and compactness in a 5.99mm x 8.66mm footprint.
