Fixed Inductors are inductors that have inductance value that is not adjustable. The Core Type and coil construction will determine the inductance value of these types of inductors. The most common fixed inductors are air core, ferrite core, toroidal, and molded core types.

The DFEH7030D-100M is a surface-mounted, molded-core, fixed inductor that is specifically designed for high current power supplies and other high current power handling applications. The inductor features a three pin configuration - two pins in the center which act as a cathode to the inductor, and one pin on the left side which serves as the anode.

The inductor has a maximum rating of 100mA, and an impedance of 3 ohms. This makes it ideal for current-limited power supplies and other applications requiring a low-impedance source.

The working principle of the DFEH7030D-100M is based on the principle of inductance. When current passes through the inductor, a counter EMF (electromotive force) is induced in the opposite direction. This counter EMF, together with the resistance of the inductor, helps to limit the current passing through it. This is why the inductor is able to provide a low-impedance source in applications requiring current-limited power supplies.

The DFEH7030D-100M is particularly well suited for applications such as switching power supplies, voltage regulators, DC-DC converters, and other high-current power supplies. It can also be used in other applications such as audio and high-precision tests and measurements, as well as in automotive and power electronics.

In order to get the most out of the DFEH7030D-100M, careful consideration should be taken into account when designing the circuit. The inductor should be placed close to the power supply, and the heat sink should be located as close as possible to the inductor so that it can dissipate the heat generated by the inductor. Additionally, the inductor should be connected to the circuit properly in order to ensure that its performance is not compromised.

In conclusion, the DFEH7030D-100M is a high-quality, surface-mounted, molded-core fixed inductor that is ideal for high-current power supplies and other high-current power handling applications. It is a low-impedance source and has a maximum rating of 100mA and an impedance of 3 ohms. Careful consideration should be given when designing the circuit in order to ensure that the inductor’s performance is not compromised.
