PE-0805CM681KTT

Fixed inductors come in many different shapes and sizes. The PE-0805CM681KTT is no exception. A traditional three-terminal, surface-mount inductor, the PE-0805CM681KTT has numerous applications and a simple, yet effective, working principle.

Application Field:
The PE-0805CM681KTT is most often used in AC-DC continuous and switching mode power supplies, switching converters, and in voltage regulators. It also has applications in automobile electronics, information and communication systems, computer and consumer electronics, and various other applications where small sizes, high performance, and low-cost components are needed.

Working Principle:
At its core, the PE-0805CM681KTT is a three-terminal inductor. A current signal entering the first terminal causes a varying magnetic field to be produced. This field then induces an electromotive force in the second terminal. This force drives a current back through the inductor, exiting at the third terminal. The resulting current signal is the same as the original, only of opposite polarity. The inductor is then said to have “phase shifted” the signal 180°.

The key to this phase shifting process lies in the way the PE-0805CM681KTT is designed. The inductor is manufactured from two thin ferrite cores with powdered iron filling. The magnetic field produced by the current signal is concentrated into the cores and is thus able to induce a more powerful field in the second terminal. This field is then passed back along through the third terminal to produce a magnetically-driven current.

The power handling capabilities of the PE-0805CM681KTT depend upon its ability to store and transfer energy, otherwise known as its inductance. This inductance is measured in henries and indicates how well the component can handle high frequencies. The power handling capabilities of the component are also influenced by its DCR, or direct current resistance; this is the amount of resistance the inductor offers to powered current signals.

In summary, the PE-0805CM681KTT is a three-terminal surface mount inductor ideal for the applications mentioned above. Its efficiency and low-cost make it an ideal choice for a variety of industries. Its working principle is based upon induction, whereby a current signal entering at one terminal induces an opposing field in the second terminal, which is then returned back through the third terminal. The inductance of the component determines its power handling capabilities, while its DCR measures the resistance it offers to powered current signals.
