GS4A032702FFT

GS4A032702FFT Description

The GS4A032702FFT from TT Electronics/IRC is a high-precision 27KΩ, 1% tolerance resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features four isolated thin-film resistors with a ±25ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The device offers a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical reliability.
