GS4B025101FDT Description

The GS4B025101FDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed with thin-film technology on a ceramic substrate, it offers precision resistance values of 5.1KΩ with a tight ±1% absolute tolerance and ±0.5% ratio tolerance. The device operates over a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. Its ±50ppm/°C temperature coefficient ensures stable performance under thermal stress. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling and compactness in surface-mount applications.
