The SRF0905-471Y is a line filter inductor from Bourns' SRF0905 series, designed for electromagnetic interference (EMI) suppression applications. It features an inductance of 470 µH (±50%), a maximum DC resistance of 0.14 O per winding, and a rated current of 1.1 A at 80 Vdc. The device operates across a frequency range of 2 to 20 MHz with a minimum impedance value of 1000 O, and is constructed with a ferrite core and enameled copper wire for reliable performance. Operating over a temperature range of -40°C to +105°C with a maximum temperature rise of 45°C at rated current, this component is ideal for power supply filtering, signal line protection, and noise reduction in electronic equipment requiring RoHS compliance.
