Fixed Inductors

Fixed Inductors, commonly referred to as inductors, are electronic components that store energy from a current in an electromagnetic field. The specific type of inductor we’ll be discussing is the CDRH4D14HPNP-220MC.

How Do Fixed Inductors Work?

The basic nature of a fixed inductor comes from the interaction between an electric current in a conductor and the magnetic fields. This interaction causes an inductive reaction when current is applied through the windings of the inductor. This inductive reaction is measured in a unit called a henry (H). The value of inductance of a fixed inductor is measured in millihenries (mH) or microhenries (µH). A fixed inductor is made up of two basic parts: the core and the winding. The core consists of a solid material, usually some form of metal, that is used to generate the magnetic field. The windings are made of insulated wire and are usually wound around the core in a spiral or helix pattern.

Application Field

CDRH4D14HPNP-220MC is a fixed inductor that is used in various electronic applications. One of the most common applications of CDRH4D14HPNP-220MC is the sensing of the motor speed. When the current in the motor increases, the CDRH4D14HPNP-220MC inductor generates a flux in the direction opposite to the motor current direction. This flux, in turn, induces an EMF in the motor’s coils which helps to sense the motor speed.CDRH4D14HPNP-220MC can also be used for filtering noise in a power supply. The inductor acts as a low-pass filter that removes high-frequency signals from the high frequency components in the supply. This helps to reduce the amount of noise that can be found in the system.The CDRH4D14HPNP-220MC also finds use in RF circuits. The inductor is placed in series with capacitors to form an LC filter which is used to suppress spurious signals and unwanted noise. The presence of the inductor also helps to keep the impedance of the filter constant across a wide range of frequencies.

Conclusion

Fixed inductors, such as CDRH4D14HPNP-220MC, are versatile components and can be used in a variety of applications. They are used in motor speed sensing, power supply noise filtering, and RF circuit applications. Understanding the working principle and application field of fixed inductors is important when selecting the right component for the right application.
