Fixed Inductors

Fixed Inductors are passive components, usually composed of a coil wound around an iron or ferrite core. They are used in various types of electronics, from low-power consumer products to high-power industrial equipment. Fixed inductors can be found in many everyday electronics such as televisions, DVD players, home theaters, automotive audio systems, and computers.

The MHQ1005PR15JTD25 is a fixed inductor designed for use in power supply circuits, particularly those with constant current up to 4A. It is a surface-mount inductor with a copper-plated 40% Ni/Fe alloy core and an outer plastic casing for protection. It has a rated inductance of 10µH +/- 20% and a resistance of 0.16 ohms max at 10 kHz. It has a temperature range of -30°C to +85°C and a self-resonant frequency of 12.5 mhz. It has a combined inductance tolerance of +20/-20%.

The working principle of the MHQ1005PR15JTD25 is based on the principles of electromagnetic induction. This states that when a changing electric current passes through a conductor, an electromagnetic field is created. If this conductor is wound into a coil, the field within this coil will be amplified many times as a result of the cumulative effect created from the individual turns of the coil. It is this electromagnetic field which is used in fixed inductors, to store and release energy.

When electric current passes through the coil of the fixed inductor, it will create an electromagnetic field which will, in turn, induce a voltage into the coil itself. The magnitude of the induced voltage is related to the amount of current passing through the coil, the inductance of the coil and rate of change of the current. When the current in the coil is static, no voltage is induced, so the wire can be used to pass a steady current without any disturbance. However, if the current passing through the coil begins to change, a voltage will be induced which will oppose this change, creating an opposing current.

The MHQ1005PR15JTD25 is extensively used in a variety of electronics as it provides excellent shielding from EM interference and offers a low-impedance operation, allowing for higher efficiency performance. Its ability to store and release energy makes it suitable for use in power supply applications such as DC/DC converters, which require an inductive component to regulate the current.

In conclusion, the MHQ1005PR15JTD25 is a fixed inductor designed for use in power applications. Its working principle is based on the principles of electromagnetic induction; when electric current passes through the coil of the fixed inductor, it will create an electromagnetic field which induces a voltage into the coil itself, opposing any change in current. Its low-impedance operation and high power efficiency make it suitable for many power applications.
