GS4A039102FFT

GS4A039102FFT Description

The GS4A039102FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 91 kΩ and a tight ±1% absolute tolerance. Its ±25 ppm/°C temperature coefficient ensures minimal resistance drift across the operating range of -70°C to +125°C, making it suitable for environments with fluctuating temperatures. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, while the gull-wing termination facilitates easy surface-mount assembly. With a maximum voltage rating of 100V and a power rating of 0.1W per resistor (0.4W total), this network balances performance and durability.
