Introduction

The PM7032S-3R3M is a Fixed Inductor, which means it is a passive electric device consisting of a coil of insulated, wound wire that acts as a magnetically-controlled current source. This specific model is used in various applications such as high-frequency resonant circuits, single-ended input DC/DC converter circuits, input/output coupling circuits, and line filter circuits.

Applications

The PM7032S-3R3M is ideal for use in high frequency resonant circuits due to its fast acting damping properties. Additionally, it can also be used for single-ended input DC/DC converters and input/output coupling circuits where small size and low profile are required as it measures in at 1.6mm L x 1.2mm W x 0.8mm H. Line filter circuits can also benefit from the PM7032S-3R3M as it exhibits multi-resonant characteristics. In addition, its high-frequency characteristics enable it to be used in communication equipment, power suppliers, game console, digital products, and automobile electrical products.

Working Principle

The PM7032S-3R3M’s basic working principle is based on the creation of a magnetic field. As current passes through the coil of wire, a constant magnetic field is produced. This field can be used to control the current flow, allowing the user to accurately alter the amount of current passing through the PM7032S-3R3M.The inductance of the PM7032S-3R3M is determined by the size of the coil, as the number of windings, and the gauge of wire used. The inductance of an inductor is a measure of its resistance to the flow of an alternating current. As the applied frequency increases, more and more of the applied energy creates an opposing magnetic field which then results in less and less energy being delivered to the output. As such, the PM7032S-3R3M is capable of damping frequencies at extremely short times in order to increase efficiency over the frequency range.

Conclusion

The PM7032S-3R3M is a Fixed Inductor designed for high frequency applications such as high frequency resonant circuits, single-ended input DC/DC converters, input/output coupling circuits, and line filter. As current passes through its coil of wire, a constant magnetic field is generated, resulting in a controlled current flow. The inductance of the PM7032S-3R3M is determined by the size of the coil, number of windings, and gauge of wire used. Additionally, its multi-resonant characteristics enable it to damp frequencies over an extensive and wide range of frequencies for increased efficiency in communication equipment, power suppliers, game consoles, digital products, and automobile electrical products.
