Fixed inductors are devices consisting of inductors with a fixed inductance. Theoretically, when the current through the inductor changes, there will be an associated change in voltage across the inductor, a phenomenon known as "inductance." The encapsulated unit is usually made of metal or ferrite, and is usually cylindrical in shape. Generally, the two ends of the fixed inductor are both connected to external leads.

RCH855NP-8R2M is a fixed inductor with a rated current of 8 A and a rated temperature of 130℃. It is made of ferrite with a round shape. It is widely used in automotive and commercial applications for high power DC to DC converters, power supplies, chargers, and mobile phone applications due to its advantages such as high current rating, high temperature rating, and low temperature coefficient.

The working principle of the fixed inductor is based on Faraday’s law of induction. When electric current passes through the inductor, it generates an electrical field. This field is proportional to the current and inductance of the inductor. In other words, when the current passes through the inductor, it creates a magnetic field around it which is induced by the current. When the current changes, the magnetic field changes accordingly, leading to a change in voltage.

The working process of RCH855NP-8R2M is exactly as same as the basic working principle of fixed inductors. The only difference is the material of the inductor. The RCH855NP-8R2M is made of ferrite, which has better properties than traditional metal inductors. It is able to endure higher temperature and is more stable in terms of temperature coefficient. This makes RCH855NP-8R2M a better choice for high power DC to DC converters, power supplies, and chargers.

In conclusion, RCH855NP-8R2M is a fixed inductor with a rated current of 8 A and a rated temperature of 130℃, which is widely used in automotive and commercial applications due to its advantages such as high current rating, high temperature rating, and low temperature coefficient. Its working principle is based on Faraday’s law of induction, in which a changing current creates a changing electromagnetic field, leading to a change in voltage.
