ER1840-02KP

Fixed Inductors

Fixed inductors are components designed to provide a set amount of inductance to a circuit. Commonly found in a variety of electronic systems, inductors are essential in applications such as signal filtering, energy storage, and motor inductance. An important type of fixed inductor is the ER1840-02KP, which has a wide range of applications and possesses many unique features.

ER1840-02KP Application Fields

This type of inductor is capable of handling currents up to 40A, providing great power conduits for its small structure, measuring only 18.7 x 20.2 x 14.22mm. Perfect for high-frequency operations, the ER1840-02KP can operate up to 2MHz with minimal losses. Commonly, these inductors are used in wide range of electronic equipment, including automotive systems, computers, laptops, or act as common-mode filter.

More specifically, the ER1840-02KP inductors are frequently used for DC/DC conversion as they are able to convert one DC voltage to another using a process known as buck-boost conversion. This type of inductor is also useful for performing power filtering, including the elimination of chokes, elimination of electrical interference noise in automotive systems and high-power audio systems, and other low-dropout applications.

ER1840-02KP Working Principle

The working principle of the ER1840-02KP is similar to that of any other inductor. It utilizes the process of induction wherein a varying current is applied across a conducting coil. This causes a circulating of electrons within the coil, creating an electromotive force (EMF). This EMF then resists any changes to the current, resulting in a magnetic field.

The magnitude of the coil’s inductance is determined by the dimensions of the coil, the number of turns in the coil, and the material of the conductive core. In the case of the ER1840-02KP, the value of the inductance can range from 10 to 420µH. The higher the inductance value, the larger the energy storage capacity of the inductor. This is important to note as higher inductance values provide better noise immunity and protection.

Conclusion

The ER1840-02KP is a fixed inductor that has a wide range of application fields, and which utilizes a standard induction process. Its popularity stems from its ability to handle high currents up to 40A, moderate frequencies up to 2MHz, and its small structure size. As a result, it is ideal for a variety of applications, including DC/DC conversion, buck-boost conversion, and power filtering.
