Fixed inductors like ER1641-564KM are components in the electronic circuitry of many domestic devices as well as professional and industrial-grade equipment.Just like other types of inductors, it works by inducing a chemical current when paired with an AC power source. Here, we’ll explain it in more detail.

ER1641-564KM Basic Function and Purpose

Fixed inductors are passive components that control the flow of electrical current in both high and low-impedance circuits. They work in conjunction with other components, such as capacitors, to regulate frequencies or direct current through a circuit.The ER1641-564KM, in particular, is a chip-style inductor that is designed to be fixed and not be adjusted. It is based on the EER (electro-magnetic inductor) theory, and the winding is made of a copper wire that is spray-painted with an insulation layer, in order to prevent contact oxidation.For the ER1641-564KM, this is implemented in arc-shaped magnetic cores with a narrow pitch design to save footprint. This also greatly increases the output power of the inductor, which makes it useful for a variety of applications.

ER1641-564KM Application Field and Working Principle

The ER1641-564KM is applied to various consumer as well as industrial products. Among the consumer product applications, automotive power supplies, audio equipment, and mobile phone chargers are two well-known applications in which this type of inductor can be found.In the industrial sector, optical communication transceivers, medical equipment, and industrial controllers often require the performance and reliability of this inductor. It is also used in uninterruptable power supplies (UPS) for power backup solutions.Working Principles of the InductorThe main job of an inductor, such as the ER1641-564KM, is to control electromagnetic interference (EMI), and reduce voltage side effects as a byproduct. This is achieved by storing a regular current as a magnetic field within its coil. This magnetic field assists in creating a low-impedance path for the electric current, thereby reducing the amount of energy that is lost to resistance.The inductor also works to convert between different forms of energy. It can convert AC to DC electricity or vice versa, which is extremely useful for power supplies for electronic devices.The inductor’s size and design also affects its performance. An inductor such as the ER1641-564KM is designed to have high inductance, which means it stores more energy in its magnetic field and is more effective at reducing side-effects such as EMI.

Conclusion

The ER1641-564KM is a fixed inductor specifically designed to resist EMI and other interference-causing voltage side-effects, while providing efficient conversion between different forms of energy. Its arc-shaped magnetic core and narrow pitch design make it highly suited for a variety of consumer and industrial applications.
