Fixed Inductors

Inductors are basic components in electronic circuit, and the basic function is to pass or resist current to certain degree and control current and voltage. As the core functioning element of electronic circuit, inductors usually used in power supply, electronic ballast, anti-interference, instrument and meter etc.. Recently, it has been widely applied in industry as well as consumer electronic field due to the rapid development of electronic product from analog to digital device.

The PM1608S-680M is a radial-leaded surface mount fixed inductors, and incorporated with weldable tabs, making connections easier than ever. Its construction is made up of a rectangular frame that is either made from iron alloy, ferrite, or a combination of iron alloy and ferrite. As a result, this inductor has better thermal stability and larger inductance, and provides a wider working temperature range. The inductance can range from 0.6µH to 68µH. The design of this inductor also provides better performance and quality than other traditional components.

As for the application field of this PM1608S-680M inductor, it particularly designed for consumer and communications applications. It is able to withstand operating temperatures of approximately -40°C to 125°C and operate at high frequencies up to 1MHz. The large size of the inductor allows for a maximum current rating of 2.2 amps, making it suitable for use in household appliances and audio equipment. Furthermore, the PM1608S-680M inductor has a high saturation, high temperature and low heat dissipation for its size which enables it to be widely used in DC-DC converters and filters. Moreover, this PM1608S-680M inductor is also used in LED luminaries, consumer electronics and sensors. Additionally, it is also suitable for higher power amplifier and transmitter in telephone networks.

Working Principle

The operation of an inductor is based on Faraday’s law of Electromagnetic Induction. This law states that a change in the current in a conductor or circuit produces a proportional voltage. In other words, when an inductor is placed in a magnetic field, the changing magnetic flux induces an electric current in it. The current in turn creates a complimentary field in response. The voltage generated is proportional to the rate of change of magnetic flux and is used in the calculation of inductance. In the case of a simple air-core inductor, this is done by using an alternating current. When an AC voltage is applied across the inductor, the magnetic field is disturbed, creating a change in the current.

This changing current creates an electromagnetic wave, which propagates away from the inductor. The width of the wave pulse and the inductors magnetic field determines the rate of change of its flux. This rate of change in magnetic flux is related to the inductance of the device.

In summary, the PM1608S-680M fixed inductor is a widely used component in consumer and communications applications due to its high efficiency and quality. Its operation is based on Faraday’s law of Electromagnetic Induction, and when an AC voltage is applied across the inductor, the magnetic field is disturbed, creating a change in the current. As a result, the inductance of the device is determined by the width of the wave pulse and the inductors magnetic field.
