PD104R-334K

Fixed inductors are essential components of many electronic products, so their adequate understanding and control of the characteristics of all the elements composing them are important. The PD104R-334K inductor is an example of this kind of component, so the present paper will analyze the application field and working principle of this part.

Application Field

The PD104R-334K inductor is mainly designed for power supply applications, especially in switching power supplies and power converters, and can also be used to filter AC signals. This component is light and dimensions are small but, even so, its transmission line is 500V and its power capacity is 0.8W.

It also features a saturation current of 5.4A, a self-resonant frequency of 16.67MHz, and an inductance of 33µH at 100kHz. Finally, this part has a maximum DC resistance of 0.7Ω and a high DC current capacity for its performance.

Working Principle

The PD104R-334K inductor is based on the Faraday\'s principle (an electromagnetism law) where a current (I) passing through an inductor causes a magnetic flux (Φ) to form. The quantity of flux formed is proportional to the amount of current and is expressed as Φ = LI, where L is the inductance.

Therefore, the purpose of the PD104R-334K inductor is to provide the necessary inductance and current capacity to store energy in the electromagnetic field and release it when necessary. When AC signals of lower frequencies pass through this part, they can be filtered and it can also block the current flow from DC power sources.

The PD104R-334K inductor features an effective shielding that reduces electrical interference both from external sources and between output and input sides. It also has a possible loss of energy due to the friction of current in the coils.

The maximum frequency at which the PD104R-334K inductor is designed to work is 16.67 MHz, but at higher frequencies, the losses caused by parasitic capacitances become more evident and the efficacy of the inductor is greatly reduced.

Conclusion

The PD104R-334K inductor is a component designed to meet the needs of power supplies, power converters, and AC signal filters. Its internal structure is based on Faraday\'s law where magnetic flux is proportional to the current. This part has a good shielding for the reduction of electrical interference and losses due to friction of current in the coils. Finally, the maximum frequency for this inductor is 16.67MHz, but at higher frequencies, its efficacy is greatly reduced.
