RL855-102K Working Principle

An inductor is an electrical device that stores electrical energy in the form of a magnetic field. An RL855-102K fixed inductor is an inductor that has a fixed inductance value, meaning that its inductance does not change with an external change in current or voltage. The RL855-102K works by storing energy in its magnetic field that is generated by the current passing through it. As the current passes through the inductor, it creates a magnetic field that circulates around it, storing energy in the form of a magnetic field.

The RL855-102K is made of a coil of wire, which is used as an inductive element. As the current passes through the coil, the coil begins to store energy in its magnetic field. As the current passes through the coil, the magnetic field increases, which increases the inductance of the coil. The greater the inductance, the greater the amount of energy that is stored in the coil.

When the current is switched off, the RL855-102K will discharge its stored energy in the form of a current, which will flow in the opposite direction of the current that initially passed through it. This current is known as counter electromotive force, or "back EMF". The back EMF can be used to reduce the voltage across the load or device, allowing for more efficient and reliable operation of the equipment.

Conclusion

The RL855-102K surface mount fixed inductor is an excellent choice for many types of electronic applications. It is capable of withstanding harsh environments and offers a wide range of inductances from 3.3nH to 390nH. Additionally, it eliminates the need for bulky, expensive inductors and can provide more efficient operation of equipment due to its counter electromotive force. All in all, the RL855-102K is a great choice for those looking for a reliable and efficient surface mount fixed inductor.
