PM1812-R47K-RC

Fixed inductors are devices that store energy in a magnetic field by introducing a magnetic flux in a circle, providing resistance against changes in current in a circuit. The PM1812-R47K-RC is a type of fixed inductor, specifically designed for use in DC to DC converters and other power and energy applications. This product is specifically designed to provide high-frequency stability and low operating temperatures.

Product Specifications

Current rating is at 110A /50Hz with a DC resistance of 0.09 ohms. It is built with an operating temperature range between -25°C and +125°C. The size of the inductor is 19.5mmx25mmx17.5mm, with a weight of about 12g.

Application Field

The PM1812-R47K-RC inductor is mostly used in DC to DC converters, converters for switching power supply, high-frequency lower attenuation circuits or when high efficiency is required. It is also suitable for power supplies on motor drives, robotics control, inverters, machines, and other related power and energy applications. Other applications include antenna matching, OCXO oscillators, switching power supplies, heaters, automobiles, and computers.

Working Principle

The working principle of a fixed inductor is based on Faraday\'s law of induction, which states that a changing magnetic field will induce a current in a conductor. This is the principle the PM1812-R47K-RC works on. The inductor is constructed of a coil of wire wrapped around a ferromagnetic core, which creates a magnetic field when current passes through it. As the current changes, this magnetic field also changes, inducing a voltage in the coil. This induced voltage is inversely proportional to the rate of change of the current, and this voltage can be used to regulate the current in the circuit.

The main benefit of using the PM1812-R47K-RC in these applications is its ability to provide high-frequency stability and low operating temperatures. This lowers the power requirements of the system, as well as increasing its efficiency. Another benefit is its high insulation resistance, which makes it suitable for high-power applications.

Conclusion

The PM1812-R47K-RC inductor is a high-frequency fixed inductor, specifically designed for use in DC-DC converters and other power and energy applications. It has an impressive resistance rating, is lightweight and small, and will provide increased system efficiency due to its excellent high-frequency and low-temperature specs. The main benefit of using the PM1812-R47K-RC in these applications is its ability to provide high-frequency stability and low operating temperatures.
