Fixed inductors are widely used in a variety of applications across many industries, from automotive to consumer electronics. One of the most popular models of fixed inductor is the ER1840-29JR. This article will explain what the application field and working principle of this type of inductor is.

The ER1840-29JR is a through-hole fixed inductor that is designed for use in applications with high current, high voltage, and high inductance requirements. Its through-hole design allows it to be mounted directly onto a PCB, making it very easy to use and also allowing it to handle higher thermal stresses. This inductor is suitable for applications such as resonant circuits, switch-mode power supplies, and DC/DC converters.

In regards to its working principle, the ER1840-29JR works as follows. It consists of a core which is typically made from ferrite and wound with copper wire. When an electric current is passed through the wire, it generates an electromagnetic field around it, due to the action of Lorentz force. This field in turn carries energy, and the amount of energy contained in the field depends on the frequency of the current, as well as on the inductance of the core. The inductance of the core can be determined by its size, the type of material, and the number of turns of the copper wire used.

The ER1840-29JR is rated for a current range of up to 10A with a maximum voltage of 5V. It has an inductance range of 0.47μH to 47μH, with an operating temperature range of -30°C to 40°C. It has a maximum SRF frequency of 950MHz. Its performance characteristics make it suitable for use in applications where a highly efficient and reliable inductor is required.

In conclusion, the ER1840-29JR is a fixed inductor designed for applications with high current, high voltage, and high inductance requirements. It works on the principle of Lorentz force, whereby an electric current generates an electromagnetic field around it that carries energy, and the amount of energy is determined by the frequency of the current and the inductance of the core. Its performance characteristics make it suitable for a variety of high-power applications such as resonant circuits, switch-mode power supplies, and DC/DC converters.
