Fixed Inductors

Fixed inductors, also called line filters or chokes, are passive components that are used to reduce unwanted electrical noise, provide impedance matching for RF communications, or store energy like a battery. The IMS02RU2R7K is a surface-mounted, ferrite-core, fixed inductor intended for a variety of applications. It is ideal for switching power converters, AC/DC power supplies, as well as EMI filtering and EMC/EMI protection.

Application Field

The IMS02RU2R7K is designed for a wide range of applications, including power-supply filtration, power-supply noise reduction, inrush current limiters, harmonic filtering, pulse transformer, and RF transmission lines. It is suitable for device protection, current sensing, and field inductors in switching-mode power supplies. Furthermore, its low profile makes it a great choice for applications where height is a consideration.

Working Principle

The IMS02RU2R7K is a ferrite-cored, fixed inductor which works by using the principle of electromagnetic induction. Under normal conditions, when an alternating current (AC) passes through the device, it induces a magnetic field around it. The strength of this field is proportional to the input current, and the reverse is also true—a varying magnetic field will induce a current. The device harnesses this phenomenon, using the varying magnetic field to produce a voltage across the inductor’s terminals. This voltage can then be used to reduce or block the flow of unwanted AC signals, or to provide a low-impedance path to DC, depending on the application.

Structure

The IMS02RU2R7K consists of three main parts: the core, the ferrite material, and the winding. The core is composed of a ferrite material, which is an iron-based powder that is highly permeable to magnetic fields. The material, as well as the size and shape of the core, determine the inductor’s inductance value. The winding is composed of copper wire, which encircles the core and which provides the path for the current to flow through the device. The inductor also contains capacitors, which are used to reduce the unwanted RF signals that pass through the inductor, and to improve the inductor’s EMI noise protection capabilities.

Performace Characteristic

The IMS02RU2R7K has a variety of performance characteristics, including increased power handling, low insertion loss, and low impedance. It also offers a wide range of inductance values, allowing it to be used in a variety of applications. Furthermore, it can operate effectively over an extended temperature range, with maximum operating temperatures of up to 105°C. In addition, the device is UL approved and RoHS complaint, making it suitable for use in a variety of applications.

Advantages

The IMS02RU2R7K offers a number of advantages over other types of inductors. Its surface-mount design makes it compatible with automated production processes, allowing it to be easily incorporated into mass production lines. It also offers a low profile, making it suitable for space-restricted applications. Furthermore, it has a wide operating temperature range and offers protection against EMI noise, both of which are important for applications where reliability is critical. Lastly, the device is UL approved and RoHS compliant.
In summary, the IMS02RU2R7K is a surface-mounted, ferrite-cored fixed inductor with a wide range of applications. It works by using the principle of electromagnetic induction to convert AC to DC, reduce unwanted electrical noise, and provide impedance matching for RF communications. The device is suitable for mass production, and offers a low profile, a wide operating temperature range, and EMI noise protection. Finally, it is UL approved and RoHS compliant, making it suitable for a variety of applications.
