#822LY-470K – TOKO

Overview

The TOKO #822LY-470K is a high-performance radial leaded choke designed for robust filtering and energy storage in demanding electronic circuits. Its core functionality lies in its inductance value of 470µH, critical for attenuating unwanted high-frequency noise while allowing desired DC or low-frequency signals to pass. A key design consideration for inductors of this type is the trade-off between core material saturation and AC resistance; while higher permeability cores offer greater inductance in smaller packages, they are more susceptible to saturation under high DC bias currents, potentially degrading performance. This RoHS compliant component offers a reliable solution for applications where precise impedance matching and effective EMI suppression are paramount.
