EF
Series
Compact RFI Filter with
IEC Connectors
UL Recognized
CSA Certified
VDE, SEMKO*, and BSI* Approved
EF Series
This rugged international series of RFI filters incorporates
the special IEC power line connector. They are UL
recognized, CSA certified, and VDE approved. Models
with F suffix are SEMKO approved and comply with BSI
standards.
Electrically the EF international series are general
purpose fllters effectively providing RFI control of line-to-
ground noise. The design is compact and meets the
very low leakage current requirements of VDE portable
equipment as well as (120 Volt) UL544 nonpatient
medical equipment. Models with F suffix have .250”
terminals on load side; EF4 and EF8 have wire leads.
Model 10EF1FC additionally incorporates a separate
ground-circuit inductor to isolate the equipment chassis
from power line ground at RF frequencies.
