Fixed Inductors

Fixed inductors are components used primarily for induction, energy storage, and harmonic filtering purposes. The ER1840-32JR fixed inductor is a specific type of small, surface-mount inductor designed to provide high levels of inductance, high current handling capabilities, and low power dissipation. Manufactured by Nippon Chemi-con Corporation, the ER1840-32JR is a popular choice for use in high-density power and automotive applications due to its reliable performance.

ER1840-32JR Application Field

Due to its small size, the ER1840-32JR is most often used in a variety of portable, dense, and/or compact applications, as well as automotive applications. It is particularly popular in low- to moderate-voltage switch-mode power supply (SMPS) circuits, DC-DC converters, and voltage regulator modules (VRMs). The device is also suitable for use in pc-board layout designs, given its higher inductance values and lower tolerances. The ER1840-32JR is widely used in applications that require maximum power density.

ER1840-32JR Working Principle

The ER1840-32JR uses an iron-core ferrite construction to achieve its high inductance levels. The device is designed so that it can be placed in very tight spaces without compromising its performance. The inductor draws its current from an external source and stores it, until it is released back into the circuit. This allows it to maintain a constant voltage and/or to inhibit the current from exceeding the rated current of the device. The ER1840-32JR also acts as a filter, blocking high-frequency interference while allowing low-frequency signals to pass through unhindered.

The ER1840-32JR\'s core is composed of a high-permeability powder electronic material, while its windings, or coils, use high-temperature coils coated with epoxy for protection against environmental fluctuations. The overall construction of the device results in low resistance at high frequencies, excellent thermal stability, and reliable inductance levels. Because of its high surface-mounting capabilities, the ER1840-32JR can also contribute to a reduction in size.

Conclusion

The ER1840-32JR fixed inductor is a small, highly efficient inductor suitable for use in dense, compact, and/or portable applications, as well as automotive applications. It is ideal for use in low- to moderate-voltage SMPS circuits, DC/DC converters, and VRMs, due to its features such as high inductance values, high current handling capabilities, low tolerance, and its ability to provide effective filtering. The device is constructed using an iron-core ferrite construction in order to allow for its impressive performance levels.
