• It can be used in the DC-DC converter for automotive voltage regulation.
• It can also be used in automotive idle stop and go systems.
• It is highly reliable for automotive powertrain applications.
• It is suitable for industrial applications such as low voltage power supplies, small motor controllers, and DC-DC converters.
• It is used in power factor control systems.
• It can also be used in AC adaptors, LCD and plasma televisions, laser printers, modern home appliances and high efficiency lighting.

Working Principle

The basic principles of a fixed inductor involve the concept of charge. It was discovered by Faraday that a steady current flowing through a conductor will produce a magnetic field around the conductor. This magnetic field can induce a voltage in electric coils if there is relative movement between the coil and the magnetic field.

In the case of a fixed inductor, the induced voltage creates a counter-electromotive force in the coil, thus limiting the current flowing through it. This opposing energy is proportional to the rate of change of the current, and the size of the inductor is a major factor in determining the degree of opposition posed by this counter-electromotive force. The induced voltage created also creates a magnetic field that opposes the changing current in the coil. This counter-magnetic field helps to keep the current constant.

The MDH7045C-680MA=P3 fixed inductor utilizes a composite core guide for increased reliability and temperature stability. The core is made from a high-temperature bonding film and an insulated metal construction. This ensures the inductor operating temperature is kept at optimal levels. The inductor’s electrical and mechanical characteristics are designed to provide effective and reliable current flow in automotive and industrial applications. Furthermore, the sealed case ensures the inductor is highly resistant against dust, oil, water, and other environmental elements.

In summary, the MDH7045C-680MA=P3 fixed inductors are ideally suited for automotive and industrial applications where there is a need to regulate current and voltage. The composite core guide allows for increased reliability and temperature stability, while the sealed case ensures resistance to dust, oil, water, and other environmental elements.
