We would be happy to help you with DC filter chokes for filtering and energy storage circuits designed for your application. Here the choke must support significant DC current while maintaining an inductance required to filter out high frequency signals. This type of inductor can be supplied with either constant or variable (e.g. linear) inductance according to your specifications.

AC filter chokes operate increasingly for switching power supplies and for filtering out transients in sensitive electronics equipment. These chokes also appear in SCR driven motor controllers to provide optimum performance. Another application is in lighting systems to eliminate buzzing when using electronic dimmer switch. The core in these AC filter chokes can be an inexpensive iron powder core or a gapped toroidal wound silicon steel core for a compact, low height design. Either way, we welcome your inquiry.
