Fixed Inductors

A fixed inductor, also known as an inductor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current is applied. It is most commonly used in electronic circuits for filtering, tuning, coupling, and power supply circuits. The PM12651S-4R7M is a fixed inductor in the 12-53 series, with a performance rating of 1.2A, 65mΩ DCR, and 4.7μH Inductance.

PM12651S-4R7M Application Field

The PM12651S-4R7M fixed inductor is commonly used in DC-DC converters, laptop power supplies, telecom systems, automotive electronics, consumer electronics, over-voltage protection circuits, mobile phone power supplies, and other related electronic power supplies. This inductor is ideal for providing a stable output voltage when the input voltage changes, and is designed to withstand high levels of heat and current for increased reliability.

PM12651S-4R7M Working Principle

The PM12651S-4R7M inductor works on the principle of mutual induction. When current is applied to one side of the inductor, a magnetic field is produced in the form of a spiral around the inductor. This magnetic field cuts through the turns of the coil, inducing a voltage in the opposite direction and opposing the current flow. The amount of opposition produced as a result of this induction is known as the inductance of the inductor.

The inductance of an inductor determines the amount of opposition it provides to changes in current. Generally speaking, the higher the inductance of an inductor, the greater the opposition provided to sudden changes in current. This in turn increases the stability of the voltage supplied by the inductor.

The PM12651S-4R7M is a high-performance fixed inductor, with a 4.7μH inductance and 1.2A performance rating. This allows it to provide a stable output voltage when the input voltage varies, making it ideal for use in applications such as mobile phone power supplies and DC-DC converters.

Conclusion

The PM12651S-4R7M is a high-performance fixed inductor designed for use in a wide range of applications. It works on the principle of mutual induction, where a magnetic field is induced in the opposite direction to oppose current flow, thus providing stable voltage. This inductor has a performance rating of 1.2A, a 4.7μH inductance, and offers reliable performance when used in mobile phone power supplies, laptop power supplies, over-voltage protection circuits, and other related electronic components.
