Fixed Inductors

Inductors are widely used in a variety of applications, and the 0819R 10F series of fixed inductors is one such example. This product line provide high quality inductors for power-switching applications that require stability and reliability.

Construction

The 0819R-10F series of inductors are constructed in a horizontal, multi-layer design to provide maximum stability for the inductor\'s current and voltage rating. The core is constructed from two pieces of high-permeability ferrite material which is then wrapped with a composite copper wire. This wire is pre-tin plated for superior electrical performance and protection from corrosion. The core plus the wire coil is then encased in resin and placed in a metal casing for mechanical stability and additional protection.

Electrical Characteristics

These inductors have a high electrical breakdown voltage, making them suitable for use in power switching applications. The inductance range offered by the 0819R-10F is between 2.4-6.8uH, in various sizes. A high current load can be carried due to the medium permeability of the core material, and the inductance can be adjusted by varying the number of turns or the diameter of the coil. The operating temperature range is -20 to +85 degrees Celsius and the maximum operating frequency is 500kHz.

Working Principle

The working principle of the 0819R-10F fixed inductors is simple - the inductor stores energy property in its internal magnetic field, which is generated by the effect of electric current flowing through it. When the current is constant, the inductance of the element stays the same and the magnetic flux associated with it maintains its magnitude. However, if the current changes, the flux density of the magnetic field varies inversely with the rate of change of current. Thus, the changing flux generates an electromotive force (EMF) in the coil that opposes the current, resulting in an inhibition of the current\'s rate of change. This reduces the magnitude of the current that is allowed to flow, resulting in an increased voltage drop or impedance.

Applications

The 0819R-10F series of inductors are mainly used for power-switching applications, where there is a need for high voltage and current ratings, stability and reliability. These inductors are also suitable for RF applications, where high inductance stability and uniformity under varying load conditions is important. They are used in hybrid circuits, power supply conditioning, and flyback converters, as well as for regulating voltage and current in cables and cordsets.

Conclusion

The 0819R-10F series of fixed inductors from TDK are designed for power-switching applications that require high voltage and current ratings, stability and reliability. These inductors can be used for a variety of applications, including hybrid circuits, power supply conditioning, and flyback converters. The working principle is based on the fact that changing current through the inductor generates a magnetic field, and this field opposes the current change, thereby reducing the current flow and increasing the voltage drop or impedance.
