Fixed inductors, such as the ER1840-16JR, are a type of passive electrical component made up of wire and other electronic material, generally consisting of a single core of ferrite surrounded by several coils of copper wire. Inductors have the property of ‘inductance’, the ability to store and release electrical energy, and they are used in a wide range of applications. The ER1840-16JR is an inductor that provides a high-frequency power source for mobile and audio applications, and offers improved operational performance.

The use of the ER1840-16JR in these types of applications is due to its design and construction features. This inductor consists of a 2.5mm x 2.5mm x 1.75mm laminated toroidal ferrite core with wire wound around it to form its coils. It has 16 turns in the toroidal core, with a current rating of 16A. The basic operating principle of all inductors is based on Faraday’s Law of Induction, which states that when a conductor carrying a current is exposed to a changing magnetic field, a voltage is induced in the conductor.

To illustrate, when a variable current passes through the inductor, a magnetic field is created around it. This can induce a voltage in the coils of the inductor. This means that the inductor is able to store energy in the form of a magnetic field. When the current is removed, the magnetic field decays and the energy stored is then slowly released back into the circuit. This effect is known as hysteresis, and it is the principle of operation for all inductors.

The ER1840-16JR is designed for high frequency use, as it has a relatively low core loss and high self-resonant frequency. This means that it can be used in applications such as power supplies, mobile phones, audio systems, and other applications that require a reliable supply of high-frequency energy. Its low core loss can also help to reduce the amount of power consumed by the device, resulting in improved energy efficiency. Additionally, the ER1840-16JR has a reverse voltage rating of 10V, offering improved protection from possible damage due to current surges.

The ER1840-16JR is a versatile and reliable component, and is suitable for use in a wide range of applications. It is well-suited for use in mobile phone, audio, and power systems, and makes it possible to store and release large amounts of energy quickly and efficiently. Its compact size and low core loss combined with its high self-resonant frequency make it an ideal choice for applications that require a reliable, high-frequency power source.
