EP/VP Series
The EP/VP series of RFI filters has been developed to
reduce conducted noise to acceptable limits for
equipment that must comply with the requirements
of CISPR in Europe and the FCC specifications in the
USA.
These filters provide high insertion loss for both lineto-ground and line-to-line emissions throughout the
frequency range. They are particularly well suited
for equipment that must meet both stringent emissions
specifications (such as CISPR 22, A-level and FCC
Part 15J, Class B) and the EP models meet very low
leakage current requirements.
