Part Name: $220\mu H$ Unshielded Wirewound Inductor $240mA$ $2.4\Omega$ Max Axial

Part Description: An inductor is a passive electronic device that is used to control the inductance of a given part of a circuit. They typically consist of a coiled conductive wire surrounding a core. The property of inductance describes resistance to change in current, or more explicitly, the ratio of voltage to rate of change of current. As the rate of current flow through the coil changes, it induces a magnetic field with a voltage polarity that opposes the change in current that caused it. Hence, they resist that change in current! Inductors are another example of a passive component used to control the overall impedance of a circuit (alongside e.g. resistors and capacitors).
