Fixed Inductors

A fixed inductor is an electromechanical device that stores energy in the form of a magnetic field. This type of inductor is typically used to produce a specific amount of energy that is used to power electrical equipment or signals. The energy stored in a fixed inductor can either be released to the equipment or used to regulate or keep power levels within a certain range. In some cases, the inductor is used to filter out unwanted components in a signal, such as noise or unwanted harmonics.

The IM04BH101J is a fixed inductor that is used primarily in the automotive industry. It has a nominal inductance of 10.3uH and is rated to handle a maximum dc current of 8A. This inductor is typically used in applications such as power converters, on-board chargers, and DCDC converters. It is also used for filters, noise reduction, and damping of the current ripple in under- and over-voltage applications. This inductor is unique in its ability to provide an operating temperature range of-55℃to +155℃, while also having a low DCR that is ideal for automotive applications.

The working principle of a fixed inductor is relatively simple. It consists of a coil of wire which is usually made from copper or aluminum, suspended between two permanent magnets. When an electrical current is applied to the coil, a magnetic field is created. This magnetic field stores energy. When the current is removed, the stored energy is released, generating a voltage across the coil. This voltage is then used to power the electrical equipment.

In the case of the IM04BH101J inductor, the inductance is 10.3uH at a nominal operating temperature of 25℃. This is determined by measuring the inductance of the coil at different applied currents, over a range of temperatures. To ensure the optimal performance of the inductor, the circuit design must ensure that the operating temperature remains within the specified operating temperature range.

In conclusion, the IM04BH101J fixed inductor is used primarily in automotive applications such as power converters, on-board chargers, and DCDC converters. It is also used for filters, noise reduction, and damping of the current ripple in under- and over-voltage applications. The inductance of the coil is 10.3uH and the current rating is 8A, with a specified operating temperature range of-55℃to +155℃. The working principle of a fixed inductor consists of a coil of wire, suspended between two permanent magnets, which creates a magnetic field when an electrical current is applied. Once the current is removed, the stored energy is released, generating a voltage across the coil.
