Fixed inductors are passive electronic components that store energy in the form of a magnetic field when exposed to an electric current. The fixed inductor with the model ER1537-19JM is commonly used in many applications and has its own working principle.

The ER1537-19JM is a ceramic surface-mount fixed inductor, and its application field is mainly in LCD TVs and mobile phones. This inductor has low DC resistance, high inductance efficiency and low parasitic capacitance. It is also available in 0603, 0805 and 0402 packages. The inductance rating of ER1537-19JM is 0.47uH. With a high self-resonant frequency, this inductor has excellent energy conversion capability and high stability.

The working principle of this fixed inductor is based on Faraday’s law of induction. Faraday’s law states that when a conductor carrying electric current is placed in a changing magnetic field, an electromagnetic force is generated. This electromagnetic force is the inductance and it is proportional to the number of turns of the conductor. For the ER1537-19JM, the number of turns is 4. When the inductor is exposed to an alternating voltage, an alternating magnetic flux is generated, inducing a voltage in the coil which is proportional to the rate of change of the current.

The ER1537-19JM is specially designed with high-frequency noise suppression. This reduces electromagnetic interference in electronic devices. It also has high efficiency, low ESR and low core loss characteristics, making it suitable for use in high-frequency switching power supplies. The inductor is highly resistant to mechanical shock and heat as well as moisture, allowing for a broad range of applications.

The ER1537-19JM is a reliable surface mount fixed inductor and its application field stretches from mobile phones, LCD TVs to high-frequency switching power supplies. As a device based on Faraday’s law, it can generate an electromagnetic force when exposed to fluctuating current, making it the ideal choice for use in many applications.
