Fixed inductors, or as they are often called in the industry, coils, are made up of electrical conductors and coils of wire, which generate an electromagnetic field when an electrical current is applied. This type of inductor is characterized by a set of parameters such as inductance and/or quality factor. PM105-101K-RC is one type of fixed inductors, which is widely used in many applications.

PM105-101K-RC is a surface mount inductor with an inductance of 101uH and a maximum DC current of 1.05 Amps. It is encased in a 0.7" square metalized epoxy package and is rated for 0.9 Watts when direct mounded. PM105-101K-RC is suitable for a wide range of current transducer applications ranging from 5 kHz to 500 kHz, from power switching applications to decoupling applications.

The basic working principle of PM105-101K-RC inductor is based on Faradays’ law and Lenz’s law. Faraday’s law states that when an electrical current flows through a conductor, a magnetic field is created that is proportional to the current and the magnitude of the field depends on the conductor’s area. Lenz’s law states that a induced current in a closed loop will always produce a current in a direction that opposes the changing magnetic field. Thus, when an electrical current is applied through the PM105-101K-RC inductor, it will generate an magnetic field that will cause a current to flow in a direction that opposes the changing magnetic field and will result in the creation of a back EMF (electromagnetic field).

PM105-101K-RC is suitable for applications in the 5kHz to 500kHz frequency range and is ideal for a wide range of current transducer applications such as power switching, decoupling, and audio filtering. It is also suitable for use in high frequency switching power supplies, motor drives, audio equipment, and ventilation systems. In addition, PM105-101K-RC is used in DC/DC converters, low drop out regulators, and for EMI/EMC noise suppression in automotive applications.

PM105-101K-RC is an excellent choice for applications where current transduction and/or power switching is required. Its small size allows easy integration into many applications and its wide frequency range makes it an ideal choice for high frequency switching power supplies, motor drives, audio equipment, and ventilation systems. The combination of Faraday’s law of induction and Lenz’s law results in the high efficiency of PM105-101K-RC inductors.
