The Mm-0787-80B filter is designed for use with large
computer or motor installations where heavy current is
drawn continuously. This filter can handle large in-rush
current typical of modern power supplies.
When data lines or power is shared with other systems
the ground coil helps breakup ground loops which can
cause system errors and also increase conducted RF
emissions.
