Introduction of Fixed Inductors

Fixed inductors are electronic components mainly used in circuits for storing energy in the form of magnetic, radiation, or electrical fields. They are often used in filters for limiting operating frequencies, and as passives to introduce dampening effects. Generally, fixed inductors have many different types such as winding inductors, chip inductors, chip antenna inductors and power inductors.

Application Field and Working Principle of B78108S1105J009

B78108S1105J009 is a winding type fixed inductor from EPCOS. It is designed for applications requiring shielded indoor use. It is primarily used in DC-DC converters, AC/DC power supplies and low frequency amplifiers.B78108S1105J009 works with the concept of mutual inductance. This means that when a current flows from one circuit to another, inductors will induce current in the opposite direction due to electromagnetic coupling. This produces another current in the opposite direction and induces a voltage across the inductor.The most important main parameters of B78108S1105J009 are its inductance, rated current and rated voltage. For this product, its inductance is 110uH, its rated current is 5.6 A and its rated voltage is 250VAC.It has a self-shielding construction that reduces noise and induces a high magnetic field. This shield also creates high air-gap permeability and prevents unwanted change in inductance due to contact with mechanical objects. For a detailed view of the shielding properties of B78108S1105J009, a cross-sectional view can be seen below.The electrical properties of B78108S1105J009 can be adjusted by changing the amount of turns within the winding. This increases or decreases the inductance of the inductor and provides a higher or lower impedance at certain frequencies. This is how an inductor can control a signal and filter out any frequencies outside of its target band.The mechanical properties of the inductor are also important to consider. B78108S1105J009 has a UL94V-0 rated polyamide insulation material rating as well as a high temperature (up to +125°C) rating. This ensures the quality and reliability of the inductor.

Conclusion

In conclusion, B78108S1105J009 is a winding type fixed inductor from EPCOS. It is designed for indoor applications requiring shielded use, such as DC-DC converters, AC/DC power supplies and low frequency amplifiers. It has a self-shielding construction to reduce noise, which can be adjusted by changing the number of turns in the windings to achieve higher or lower inductance values. It also has a UL94V-0 rated polyamide insulation material and a high temperature rating of +125°C which ensures the safety of the component.
