Leaded Inductors

Leaded inductors are devices that work as resistors to alter voltages and absorb electromagnetic interference, which can influence the status of electrical circuits in equipment. Leaded inductors are made of coils around magnetic cores and store energy as a magnetic field rather than an electric field, which is the way a capacitor stores energy. Leaded inductors come in a variety of shapes and sizes from RS Components, including axial, radial, through-hole, and panel-mount inductors.

What are Leaded Inductors Used for?

In both low-voltage and high-voltage circuits, asymmetrical interferences are suppressed using led inductors. Although they frequently have ferrite cores, leaded inductors can also have cores comprised of nanocrystalline materials or iron. They don't affect the signal when the voltage is low or DC and operate as continuous circuits to maintain the current flowing in the event of interference. Due to their high resistance, they may effectively block current flow in high voltage applications, protecting the circuit from damage-causing voltage spikes.

Types of Leaded Inductors

These inductors are available in a variety of geometries, such as linear, axial, radial, and through-hole components, with leads attached concentrically to the inductor cores' opposite ends.

Lead inductors come in two main types, VHF-choke and RF-choke:

  • VHF (very high frequency) versions are employed for line voltage applications to stop or filter EMI in minute applications or for decoupling in telecom and amusement electronics.
  • RF (radio frequency) versions are employed in low-frequency applications of the sensor signal and monitor circuits and are manufactured to block radio frequencies at the same time allowing audio signals to be transmitted.
