Fixed inductors are passive electrical devices that are typically used in electronics circuits to store energy in the form of an electromagnetic field. In general, inductors have the inverse characteristics of capacitors and are used to regulate the flow of electricity in a circuit. The PM3308-471M-RC Inductor, developed by Pulse Electronics, is a device for electronic circuits to effectively store and deliver the energy required to achieve desired output.The PM3308-471M-RC utilizes a fixed inductor, with a leaded, Radial package shape and is constructed of molded ceramic body composed of NiZn ferrite. It possesses a RoHS compliant termination and insulation system that ensures its reliability, stability, and durability. This inductor is rated at 4.7uH (±10%), with an inductance tolerance of 0.10uH, a DC resistance of 0.090 Ω, and a high saturation current of 2.4A (I max). Additionally, the PM3308-471M-RC is able to operate safely at a temperature range of -25°C to +125°C. The PM3308-471M-RC is ideal for low power consumption, mobile, consumer, and military applications, finding use in a wide range of products such as mobile phones, digital TVs, consumer audio and LED lighting. Moreover, Pulse Electronics’ PM3308-471M-RC fixed inductor is renowned for its reliable performance in applications subjected to extreme temperatures.The working principle of the PM3308-471M-RC fixed inductor is essentially based on Faraday’s law of electromagnetic induction, which states that the induced electromotive force (EMF) in a circuit is proportional to the rate of change of the magnetic flux. This principle explains why the electric current induced in a coil, when a changing magnetic field is applied, opposes the change; this phenomenon is known as inductive reactance.The PM3308-471M-RC fixed inductor stores energy in the form of electromagnetic field and returns it to the circuit. This inductor consists of a coil of wire wrapped around a magnetic core, such as an iron core. When an alternating current flows through the coils, a magentic field is created that is stored in the core. This process happens continuously as long as the current flows, so that the magnetic field stored in the core remains virtually constant.This stored energy can be returned to the circuit as a voltage when the current is removed. The voltage is regulated thanks to the inductors inherent property known as inductance. Inductance is the measure of how much an inductor resists changes in current. As the current passes through the coils, it is opposed by a regenerative magnetic field, or reactance. This attribute helps to ensure that the current’s flow is steady and remains within the desired range.In conclusion, Pulse Electronics’ PM3308-471M-RC fixed inductor is equipped with a RoHS compliant termination and insulation system, is ideal for low power consumption, mobile, consumer and military applications and possesses a high saturation current of 2.4A (I max). The PM3308-471M-RC utilizes Faraday’s principle of electromagnetic induction and stores energy in the form of an electromagnetic field, which, when returning it to the circuit, is regulated by the inductors inherent property of inductance.
