Fixed inductors are electrical components used to store energy in an electromagnetic field. Fixed inductors are essential components for many types of electronic systems and devices, including communication systems, electrical motors, power supplies, automotive systems, portable devices, and more. ER1641-332JP is a special type of fixed inductor. This article will discuss the application field and working principle of the ER1641-332JP.

The ER1641-332JP is a fixed, shielded power inductor designed for use in automotive DC/DC converters and DC/DC isolators. It is designed to provide high current with low profile, low EMI, and low heat dissipation. The inductor has a inductance value of 3.3uH, current rating of 2.2A and resistance of 264mohms. Its maximum DCR of 0.6 ohms provides better current carrying capacity. It also features a shielded construction with 12mm primary bobbin size, which helps to reduce the magnetic field interference.

The ER1641-332JP is suitable for a wide range of automotive applications, including but not limited to DC/DC converters, DC/DC isolators, power supplies, and motor control. It is an ideal component for applications that require high current, low profile, and low EMI. Its shielded construction makes it suitable for installations in automotive environments where there may be electromagnetic interference or other sources of noise.

The working principle of the ER1641-332JP is based on electromagnetic induction. When a current carrying wire is placed in a Magnetic field, a voltage will be induced in the wire, and the induced voltage will be determined by the strength of the magnetic field, the number of turns of the wire, and the rate of change of the magnetic field. In this case, the inductor consists of coils of insulated wire placed in a magnetic core, and when an alternating current is supplied to the coils an alternating magnetic field is created. This magnetic field causes a voltage to be induced in the coils, thus creating a stored electrical energy. As the current in the coil is increased, it induces a voltage in the coil and the energy in the magnetic field is increased.

As the current in the coil is increased, it induces greater and greater voltage and the stored energy increases until it reaches the maximum rated current of the inductor. At this point, the amount of energy stored in the magnetic field is limited and the inductor\'s inductance decreases with increasing current. This ensures that the inductor does not overheat at high current levels.

The ER1641-332JP is a high-performance fixed inductor designed for use in automotive DC/DC converters and DC/DC isolators. It features a shielded construction with 12mm primary bobbin size, providing excellent high-frequency noise suppression and low profile. It can carry a high current of up to 2.2A while exhibiting low EMI and low heat dissipation. The inductor is ideal for a wide range of automotive applications, including DC/DC converters, DC/DC isolators, power supplies, and motor control.
