Fixed inductors refer to the devices inductance, which have a relatively convolute relationship to the current and of physical properties. Fixed inductors are widely used to provide AC and DC currents with limiting the voltage and current to acceptable levels in many applications, such as power supplies, DC-DC converters, audio equipment, RF circuits, and so on. The IFCB0402ER12NJ is a type of fixed inductors made of ferrite material. It can operate in wide temperature range from -55°C to 105°C and provides excellent Q values and SRF performance.

The IFCB0402ER12NJ features high inductance values ranging from 0.062uH to 82uH, with a rated current up to 0.6A. Except for its ultra-low resistance, the IFCB0402ER12NJ shows low dissipation over a wide range of temperatures and a good thermal stability. To sum up, the IFCB0402ER12NJ inductor has excellently low DCR, high saturation current and high self-resonant frequency.

The IFCB0402ER12NJ is ideal for applications requiring small size, high current, good reliability and cost efficiency, like AC/DC switching mode power supplies and automotive electronics etc. It is commonly used in high frequency switching applications, DC DC converters, power supplies, automotive electronics, mobile phones and other electronic equipment. With its stable inductance, wide working temperature and stable performance, the IFCB0402ER12NJ can meet customers’ requirements very well.

The working principle of the IFCB0402ER12NJ can be explained through Faraday’s law of induction. Whenever a conductor is placed in a changing magnetic field, a voltage will be developed in the conductor. This voltage, known as electromotive force (EMF) is proportional to the rate of change of the magnetic flux passing through the conductor. This principle forms the basis of operation of a fixed inductor.

When a current flows through the IFCB0402ER12NJ’s conductors, it produces a magnetic field that varies according to the size of current in the coils. This magnetic field induces an EMF in the same conductor. The IFCB0402ER12NJ uses the generated EMF to oppose the applied voltage in production of a back EMF in order to restrain the current that passes through the inductor. This is the most basic principle of operation of all inductor devices.

Therefore, it can be concluded that the IFCB0402ER12NJ is a fixed inductor with excellent inductance value and wide temperature range. It has an excellent features like low resistance values, high current rating, and high self-resonant frequency. It can be used in multiple applications like AC/ DC switching mode power supplies, automotive electronics, and other electronic equipment. Its working principle is based on Faraday’s law of induction based on EMF generated from a changing magnetic field in the conductor which opposes the applied voltage for restraining the current flow.
