COMMON-MODE CHOKES

APPLICATION FEATURES

The JL and ML 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 ML series has a two-section printed circuit bobbin which automatically isolates the two windings.  This provides a high dielectric withstanding voltage value.  The ML series also uses a printed circuit bobbin which provides a reliable and inexpensive termination.  All the pins are left on the bobbin which results in maximum holding strength to the board.

The JL series are encapsulated in a cup which results in high density packaging and low profile.

PERFORMANCE COMPARISONS

To summarize, the EMJL series has 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.
