Aimed at power applications, the CSF series of common-mode filters features ungapped "H" ferrite cores with split-section bobbins that have been tightly wound in an automated process. This process en-sures constant leakage inductance and self-resonant frequencies. Inductance values range from 1 to 120 mH, and maximum dc currents range from 0.3 to 4.5 A. Units are available in four sizes with vertical or horizontal core mounting and industry-standard footprints. Pricing is less than $0.50 each in lots of 10,000 with delivery from stock to eight weeks.
