The FC0402E50R0BSWS is a 50R 50mW SMD edge trimmed block Chip Resistor with passivated nichrome thin film element and wraparound lead (Pb)-free solder 96.5% Sn/3.0% Ag/0.5%Cu termination. The FC series chip resistor is designed with low internal reactance. It functions as almost pure resistor on a very high range of frequencies. The specialized laser edge trimming allows for precision tolerances to 0.1%.
