SDR2207-181KL

Fixed Inductors

In modern electrical engineering, a fixed inductor refers to an electromechanical device that stores energy from an electrical current. In general, these inductors are made up of a core made from a ferromagnetic material, coupled with one or more windings of insulated copper wire. A variety of iron cores are available, including laminated, powdered, ferrite, and ceramic materials.

The SDR2207-181KL is an axial-lead lead type fixed inductor, and fits neatly into the category of fixed inductors. This particular device boasts an excellent electrical performance with a working current of 4A and inductance of 180µH. It also has a Q-factor of 78, and is rated for an operating temperature range of -40°C to +85°C.

Application Field

The main application field of the SDR2207-181KL is in power circuits that involve a current rating of up to 4A. Common applications for this particular device include output stages of switching converters such as DC/DC converters, load current stabilizers, high-power LED lighting circuits and high-power DC/AC inverters.

Working Principle

The basic process of how a fixed inductor operates is as follows: when an alternating current passes through the inductor, a magnetic field is generated in the core which stores energy. When the level of current changes, this stored energy is released in order to compensate for the change in current. The resulting magnetic field also creates a voltage, which is proportional to the change in current.

Thanks to the high quality and performance of the SDR2207-181KL device, it can operate at its maximum efficiency throughout its entire working current range. This helps to ensure a consistently high level of power delivery in high-power applications.

Conclusion

The SDR2207-181KL is an excellent example of a high quality and reliable fixed inductor, and is well-suited to applications that require a low profile and high inductance. By understanding the working principle of this type of device, and the various application fields in which it is used, it is possible to ensure that the inductor performs its task efficiently and reliably.
