Common-Mode Chokes

APPLICATION FEATURES

The JL, ML and ZL Series of chokes are offered for use in AC or DC power line to attenuate common mode noise. The magnetic circuit is designed and windings are connected in the power line so that the currents will cancel.  However, the common mode noise will be attenuated. A High-permeability ungapped ferrite core is used.

PACKAGING CONSIDERATIONS

The JL series are encapsulated in a cup which results in high density packaging and low profile. The ML series uses a printed circuit bobbin which provides a reliable and inexpensive termination.  Two-section bobbins are used which automatically isolates the two windings.  This provides a high dielectric withstanding voltage values.  All the pins are left on the bobbin which results in maximum holding strength to the board.

PERFORMANCE COMPARISONS

To summarize, the EMJL and OEZL series have the highest performance and best packaging density while the OGML series has the lowest price.  This is especially true when compared to the sector wound toroids.
