Differential mode electromagnetic noise is conducted on the supply and ground lines in opposite directions. The reason for the noise is because cross-cancelling does not happen effectively.
This type of noise is suppressed by installing a filter on the on the signal /power supply line.
Designing filters with differential mode chokes is an economic way to combine low losses, low voltage drop, minimal signal impact with efficient EMC/EMI filtering.

What EMIS Offers
EMIS range of Differential mode Choke coils are designed for use in a wide range of applications, to suppress DM noise. The common mode choke provides saturation which enables effective Differential mode suppression.
Magnetic material called ferrite is most commonly used in construction. These Chokes can be used in various AC and DC Applications.
