Inductors

Inductors are a form of passive component similar to a capacitor; they’re designed to deal with magnetism and control magnetic flux.

Inductors, also known as coils, chokes or reactors, are characterised by inductance, which is the ratio of the voltage to the rate of change of current. They’re frequently used in radio equipment to block AC and allow DC. An example of this passive component being used day-to-day is the ferrite bead on your laptop's power cable, which is designed for reducing electrical noise.

Inductors are usually a length of wire wound to create a coil around a core material with high insulator properties. However, inductors are more than just a coil of wire with an insulating material in the middle, in application, inductors are a key component to a circuit.

We sell several types of inductor:

  • Wire-wound surface mount inductors – these are usually a wire coil wrapped around a magnetic component
  • Leaded inductors - come in two main categories and are used in low and high voltage situations
  • Multi-layer surface mount inductors - this is a style of coil which has several layers of wire wrapped around an inductor, with layers of insulation added to give a high inductance level.

We also carry inductor components for both EMI and RFI and a variety of wireless charging coils. Wireless charging coils are used for DC-DC currents and are used for inductive charging; any wireless charger runs using this inductive component.
