GS4A021621FFT

GS4A021621FFT Description

The GS4A021621FFT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 1.62 kΩ resistance and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring stability in harsh environments. Its ±50 ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits. The SOIC-C series construction provides excellent thermal and mechanical reliability, while the gull-wing termination ensures secure PCB mounting. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this network is suited for both analog and digital signal conditioning.
