What is ER1641-751JR Fixed Inductor?

A Fixed Inductor is an inductor whose inductance value cannot be adjusted. ER1641-751JR is a type of Ferrite Cored Inductor which is a cylindrical coil which consists of a number of turns of insulated copper wire wound around a soft ferrite core of road. ER1641-751JR fixed inductor is often used in power supplies as filter inductors.

ER1641-751JR application field

ER1641-751JR fixed inductor is widely used in a variety of the electronic products or devices. For example, in computers, it works as a power supply filter inductor, which helps to prevent any unwanted signals or current from entering the system. In audio systems, it is used as an amplifier filter inductor to filter out the high-frequency noise. Also, it can be used as a transformer in power supplies to improve the power stability.

Working principle of ER1641-751JR

The ER1641-751JR fixed inductor works on the principle of electromagnetic induction. When an electric current is applied to the wire winding of the inductor, a magnetic field is created around the coil. The core material, which is composed of ferrite, helps to further strengthen the magnetic field. This in turn produces a magnetic flux, which induces an opposing voltage in the wire coil. This voltage opposes the original current flow, thus the inductive effect is created.The magnetic field around the inductor helps to suppress any high-frequency interference. This in turn helps to maintain a constant and stable voltage. As a result, the system is protected from any noise, which could affect the performance negatively.

Other Features of ER1641-751JR Fixed Inductor

ER1641-751JR fixed inductors also have some other features. These include a wide operating temperature range, from -40°C to +105°C. The inductance value as well as the current rating of the inductor can also be adjusted by changing the amount of wire coil used. The inductor is capable of handling high frequency noise, which makes it suitable for high-speed applications such as in computers, mobile phones, and other electronics. In addition, it also has low losses when used with high frequency current, which makes it energy efficient.

Conclusion

ER1641-751JR fixed inductor is a cylindrical component consisting of a core made of ferrite and a number of windings of insulated copper wire. It is widely used in a variety of electronic devices for power supply filter applications, amplifier filter circuits, and transformers due to its wide operating temperature range, current rating, and low losses at high frequencies. Its induction principle helps to suppress any high-frequency interference, making it suitable for high-speed applications.
