Fixed Inductors

Fixed inductors are passive electrical devices used in an electronic circuit to store energy in the form of a magnetic field. They are also known as inductors, coils, or chokes. Fixed inductors for high-frequency applications are typically made from powdered iron-core materials with high initial permeability. The ER1641-204JS is a combination of a surface mount inductor packaged in a lead-free SIP package.

ER1641-204JS Application Field

The ER1641-204JS is an inductor designed for use in modern electronic systems where size and weight reductions are required. Some of the application fields include switching power supplies, mobile phone circuits, datacommunication circuits and automotive circuitry.

ER1641-204JS Working Principle

Fixed inductors are based on the principle of electromagnetism, more specifically, Faraday’s law of induction. The ER1641-204JS is a high current inductor with high saturation current and low DCR values. When a current flows through the ER1641-204JS, a certain amount of energy is stored in the form of a magnetic field. This stored energy is released when the current is cut off, thus allowing the inductor to act as a filter or as an energy reservoir.

ER1641-204JS Performance Data

The ER1641-204JS has a wide range of performance characteristics and operational limits specified by the manufacturer. The operating temperature range is from -55C to 125C, the inductance range is from 1.2mH to 470mH, the rated current range is from 0.12A to 7.8A and the DC resistance range is from 0.013ohm to 1.6ohm. It also has a high saturation current of 9.8A and a wide tolerance range of +-10%.

Conclusion

The ER1641-204JS is an efficient and reliable surface mount inductor designed for high-frequency applications in modern electronic systems. Its combination of high current, high initial permeability and high saturation current makes it an ideal choice for a variety of applications where size and weight reductions are required. With its wide operating temperature range, low DC resistance, and broad tolerance range, the ER1641-204JS is sure to meet the requirements of many projects.
