• Three element differential mode circuit provides
the highest attenuation of any available standard
inlet filter
• High common mode inductance
• High differential mode capacitance
• Effective attenuation of Line to Ground and Line
to Line noise across the frequency range
• Performance and application similar to the ED
series but with higher differential mode
performance
• Includes several termination options

Operating Ambient Temperature Range
(at rated current Ir):
-10°C to +40°C
In an ambient temperature (Ta) higher than +40°C
the maximum operating current (Io) is calculated as
follows: Io = Ir
(85-Ta)/45
