Laminated Chokes


Laminated Chokes are typically rated in terms of max DC current, DC resistance, inductance, and a voltage rating. MCE offers a miniature DC filter choke in the OC18CL series.  In addition, MCE offers a series of chokes, primarily for use in DC power-supply smoothing-filter applications in two series:  1) the linear FL series and 2) the “swinging” NL series.

The FL series Laminated Chokes are especially suited for requirements where the DC will be 50 to 100% of I-DC rated.  They will provide the most inductance in this range.

The NL series Laminated Chokes are generally more suitable where the DC will vary between 10 to 100% of I-DC rated.  The inductance at rated I-DC is approximately 1/4 of the value at I-DC = 0.

Both series are listed by size in the tables of specifications.  The V, I-DC, and R are the same for similar part numbers, only the inductance values and characteristics are different.  All parts are available in any of the MCE Miniature Line package options (see the packaging guidelines on the home page.)

The OC18CL series can also be used as an Audio Inductor. Although these parts use lamination cores they can work in the audio range because they have significant air gaps.

Modified Standard AC Inductors can be made for higher frequencies and with a tighter tolerance of the inductance values.
