Fixed Inductors are an essential component of any electrical system for a variety of reasons, including providing high efficiency current regulation, low noise operation, and steady-state correct performance. They come in a multitude of shapes and sizes, from tiny surface mount inductors to large motor assemblies. The PM20-R022M is a specialized fixed inductor that is used in select applications due to its unique features and performance characteristics.

The PM20-R022M is a power inductor that is designed and manufactured by Murata Electronics North America. It is an unusual type of fixed inductor because it has an outer label section that is etched with copper wires that allow the part to simultaneously perform power and signal conditioning functions. This type of inductor is often used in power management systems to regulate current, reduce noise, and provide steady-state accuracy.

The PM20-R022M has a maximum peak current handling capacity of 2.2A and a maximum DC resistance of 0.080Ohms. It is designed to operate in temperature ranges of -40 to +105 Degrees Celsius. It has a high energy storage capacity of 1.15mJ and a turn-off time of 20ms. These features make it ideally suited for applications in the harsh environment of inertial guidance and aircraft flight systems. The PM20-R022M has dimensions of 12.8x8.5x9.6mm, requires no external cooling, and can operate over a wide frequency range of 5KHz to 200KHz.

The principle of operation for the PM20-R022M is based upon the concept of self-inductance. Self-inductance is the property of a circuit that stores energy in a magnetic field when current passes through it. When current passes through the coil, the result in the inductor is a voltage that opposes the flow of electricity. This voltage produces a magnetic field that displaces the electrons and imparts energy on them. The electrons then become displaced and their increase in energy causes the inductor to resist the flow of current.

The PM20-R022M works by virtue of the Eddy Current, a concept of self-inductance. The eddy current is created when the magnetic field that is generated by the inductor interacts with the current passing through it. The result is a proportionate decrease in the current that passes through the inductor. This allows the inductor to convert an AC voltage into a regulation DC voltage or lower the voltage and act as an over-current protecting device.

The PM20-R022M is an ideal solution for applications that need a reliable current regulator with a wide frequency range. This type of inductor is typically used in the design of applications such as power supply systems, high-reliability circuit designs, telecom applications, and consumer products. It is also often found in applications that require high-efficiency systems and those that control or regulate electrical current in a safe manner.

The PM20-R022M is a high-performance, high-quality fixed inductor that provides superior current regulation, low noise operation, and steady-state accurate operation. With its cutting-edge design and features, this product is ideal for high-end applications that require dependable performance in the most challenging conditions. The wide temperature range, high energy storage capacity, and turn-off time make it an ideal solution for a variety of power management systems.
