Fixed inductors are electrical components that store energy in the form of a magnetic field, typically used for inductors and chokes. HM66-153R3LFTR7 inductors, sometimes called "power ferrite," provide specialized functions within electronic circuits and can be found in a wide range of applications, from appliances and computer peripherals to switched-mode power supplies. Understanding the HM66-153R3LFTR7\'s application field and working principle is critical for properly selecting and applying this power ferrite.

Applications

Because the HM66-153R3LFTR7 is designed to stored energy in the form of magnetic flux, its primary applications are that of an inductor or choke. It is often found in switched-mode power supplies (SMPSs) that are used to power computers, mini-stereo speakers, and a wide range of computer peripherals. It is used within the SMPS as an inductor to block AC signals from passing through the circuit and providing a path for DC signals that form a controlled voltage output. As such the HM66-153R3LFTR7 acts as an electronic filter, separating DC from AC signals within a circuit.

Examples of HM66-153R3LFTR7 applications include:

• Circuit boards on desktop computers
• Circuit boards for DC/DC converters
• Chargers and adaptors

Working Principle

The HM66-153R3LFTR7 is made up of a core, winding coils, and an insulator material. The core material is composed of ferrite, which is a combination of iron oxide and metallic particles. Winding coils are wound around the core and enclose the iron oxide ferrite particles.

When electric current passes through the winding coils, a varying magnetic field is generated around the HM66-153R3LFTR7, allowing it to act as an inductor. Since inductors oppose the change of current passing through them, the magnetic field within the HM66-153R3LFTR7 captures energy from the current and stores it, essentially acting as a filter. As current passes through the winding coils, the magnetic field increases and energy is stored in the form of a magnetic flux.

Specifically, the HM66-153R3LFTR7 features an ungapped ferrite core, which helps to better store energy by providing a stronger field. Its winding coils also feature multiple conductors, providing an increased capacity for energy to store when current passes through them. This gives the HM66-153R3LFTR7 increased filtering and inductive capacity.

Conclusion

The HM66-153R3LFTR7 inductor is designed specifically for use in switched-mode power supplies, requiring an efficient inductor or choke for its operation. In this application, the HM66-153R3LFTR7 excels at providing a strong magnetic field and blocking AC signals while still allowing a path for DC signals. Its ungapped ferrite core and multiple winding coils make it an ideal choice for providing an energy-storing alternative in a wide range of applications.
