Introduction

PM5022-5R6M-RC is a fixed inductor used in various electrical circuits. It is a common component in power supplies and filters circuits, where its ability to reduce the flow of current is needed. It can also have applications in transformers, flyback converters and phase controlled rectifiers. This article covers its application field, its working principle and calculations related to its use.

Application Field

The PM5022-5R6M-RC is a non-polarized magnetic element, which cannot be used in radiofrequency circuits. Its primary application is in power supplies, where it acts as an inductor, limiting the amount of current that can flow. It is widely used in switch mode power supplies, AC-DC converters, voltage regulators, LC filters, flyback converters, phase controlled rectifiers and linear transformers.

Working Principle

The PM5022-5R6M-RC follows Lenz’s law, which states that an induced electromotive force generates a magnetic field that opposes the current change of the circuit. This means that when a current change occurs in a circuit with an inductor, the inductor will oppose the current flow by generating a counterforce. This counterforce, known as an inductance, is measured in Henries (H).

The PM5022-5R6M-RC is a fixed inductor, which means that the value of inductance is predetermined. This is done by designing the inductor with certain dimensions and core material. Depending on the application, the inductor will have different inductance values.

Calculations

When designing an electrical circuit, it is necessary to calculate the amount of current the inductor will need to induce in order to reach the desired output. This calculation is done using the following formula:

I = (V - Ldi/dt) / R

Where V is the voltage, L is the inductance, di/dt is the change in current per unit of time, and R is the resistance.

In order to calculate the amount of voltage, the following formula can be used:

V = Ldi/dt + RI

Where V is the voltage, L is the inductance, di/dt is the change in current per unit of time, and R is the resistance.

Conclusion

In conclusion, the PM5022-5R6M-RC is a fixed inductor used in various electrical circuits. It is a widely used component in power supplies, AC-DC converters, voltage regulators, LC filters, flyback converters, phase controlled rectifiers and linear transformers. It follows Lenz’s law, which states that an induced electromotive force generates a magnetic field that opposes the current change of the circuit. Calculations related to its use can be done using the aforementioned formulae.
