relief inductor

The relief inductor is designed as a magnetic component in electronic circuits with the primary function of reducing frequency interference and storing magnetic energy. It consists of a ferrite core with magnetic permeability between 2000 and 5000, wound with copper wire of 0.3 to 1.2 millimeters diameter. The inductance value ranges from 10 microhenries to 470 microhenries, with production tolerance usually below 5 percent. The equivalent series resistance or DCR is measured below 0.2 ohms, improving overall efficiency.

Paragraph 2 English:
The relief inductor can withstand continuous current from 0.5 to 15 amperes, with an operating temperature range from minus 40 to plus 125 degrees Celsius. Its optimal frequency range is 20 kilohertz to 2 megahertz, making it suitable for switching power supplies and EMI filters. An epoxy coating on the winding ensures dielectric strength above 1500 volts. Component dimensions vary from 5 by 5 millimeters to 18 by 18 millimeters, with designs available for both SMD and DIP mounting.
