RL855-120M

Fixed inductors are the most common type of electronic component in the field of electronic circuit design. The RL855-120M is a fixed inductor used in a variety of applications. The RL855-120M is a surface mount power inductor with an inductance of 120mH. It is used to suppress high-frequency noise in power supply systems.

Construction and Features

The RL855-120M is a shielded power inductor with two internal cores. Its core is made from ferrite material which is light in weight and durable. The windings are made up of enameled copper wires with a current rating of up to 3A. The inductor is encased in a rectangular metal can for protection against environmental conditions. The winding is wound with the shielding material for extra protection from external magnetic interference.

Applications

The RL855-120M is used in a variety of applications including power supplies, DC-DC converters, current filters, and circuit protection circuits. The inductor can be used as a power supply noise suppressor to minimize the noise created by switching power supplies. The inductor’s two cores make it an excellent choice for use in buck and boost circuit applications, as the cores are able to cancel out any harmonics created by the oscillation of the switching power supply. The inductor also has high current rating, allowing it to be used in applications where it is necessary to support large amounts of current. The RL855-120M is also used in low pass filter applications to reduce the effect of high frequency noise on the power supply.

Working Principle

The working principle of the RL855-120M is based on the principle of induction. When the inductor is connected to a voltage source, the current flowing through the coil causes a magnetic field to be generated. This magnetic field is then used to induce the current. As the current increases, the magnetic field increases, which in turn increases the inductance of the coil. As the current decreases, the magnetic field decreases, which in turn decreases the inductance of the coil. This allows the RL855-120M to act as a filter to reduce the effects of high-frequency noise on the power supply.

Conclusion

The RL855-120M is a fixed inductor which is used in a variety of applications. It has a high current rating of up to 3A and is encased in a metal can for protection from the environment. It is also able to reduce the effects of high-frequency noise on the power supply due to its working principle of induction. It is an ideal choice for use in power supplies, DC-DC converters, current filters, and circuit protection circuits.
