Fixed inductors

Fixed inductors, also called chokes, are components built to create an AC or DC inductance. An inductor is a type of passive circuit component that mainly storemagnetic energy around it. It is made of wound coils of wire or helical coils of thin metal. It limits and constrains electric current and helps maintain the current at a steady level.

RCH1216BNP-220M Application Field and Working Principle

RCH1216BNP-220M is a type of fixed inductors with special high-quality windings. It can store significant amount of inductance required for several applications. Its application field covers switch mode power supplies (SMPS) and recirculating small pass filters (RSPF). Since it can maintain inductance under a wide temperature range, it is also used for induction heating applications.

RCH1216BNP-220M consists of iron core and a coil of insulated copper wire. The core is made of high permeability and low losses material. There is a wide applicable temperature range of -40℃-105℃ or up to 125℃. The winding ratio of this inductor is configured with a specific number of turns with respect to its dimensions.

RCH1216BNP-220M has a different working principle than other types of inductors. It works in two ways: It can either limit the current or react it into a high-induction magnetic field. When current travels through the windings, it produces a magnetic field which is directly proportional to the current. The magnitude of the field produced depends upon the permeability of the core material. This means that if the permeability of the core material is higher, then a greater amount of energy will be stored in the field. The inductance of the fixed inductor increases as the core material increases the permeability.

RCH1216BNP-220M can also be used as a filter when combined with capacitors or resistors. The inductor is used to block the AC current while allowing the DC current to pass through it. The combination of the inductor with capacitor helps to reduce or stop any ripples caused by the AC current. The inductor also limits the DC current flow due to the high impedance created by its windings.

RCH1216BNP-220M has a wide range of uses in many applications such as switch mode power supplies, recirculating small pass filters, and induction heating. The working principle of this inductor is based on the creating and modifying the magnetic field to store energy as the current passes through it. This type of inductor is used both as a limiter and as a filter.
