GS4A011473FFT

GS4A011473FFT Description

The GS4A011473FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 147kΩ resistance per element with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in matched circuits. Its thin-film technology and ±100ppm/°C temperature coefficient provide excellent stability across a wide operating temperature range of -70°C to +125°C. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, it is ideal for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration.
