SRF0905-472Y is a line filter inductor from the SRF0905 Series designed for electromagnetic interference (EMI) suppression applications. It features an inductance of 4700 µH ± 50%, a maximum DC resistance of 0.90 O per winding, and a rated current of 0.4 A at 80 Vdc. The device operates across a frequency range of 0.3 to 3 MHz with a minimum impedance value of 4000 O, and is constructed with a ferrite core and enameled copper wire for reliable performance. With an operating temperature range of -40°C to +105°C and RoHS compliance, this component is ideal for power supply filtering, signal line protection, and noise reduction in electronic equipment where low-frequency EMI suppression is required.
