High Performance K Series RFI Line Filters for SMPS Emission Control
SK Series
SK Series
Maximum leakage current each Line to Ground:
3, 6 & 10A VSK Models ESK Models
@120 VAC 60 Hz: .4 mA .21 mA
@250 VAC 50 Hz: .7 mA .36 mA
20, 30 & 40A
@120 VAC 60 Hz: .75 mA .3 mA
@250 VAC 50 Hz: 1.25 mA .5 mA
Hipot rating (one minute):
Line to Ground: 2250 VDC
Line to Line: 1450 VDC
Rated Voltage (max): 250 VAC
Operating Frequency: 50/60 Hz
Rated Current: 3 to 40A
Operating Ambient Temperature Range
(at rated current Ir): -10°C to +40°C
In an ambient temperature (T
a) higher than +40°C
the maximum operating current (Io) is calculated as
follows: Io= Ir(85-Ta)/45
• Designed to reduce conducted noise to
acceptable limits for equipment that must comply
with FCC / EN specifications
• Utilizes significantly higher element values than
the general purpose K Series which makes them
better suited for equipment with Line to Ground
and Line to Line conducted emissions including
those with switching power supplies
• ESK6C and VSK6C incorporate separate ground
circuit inductor to isolate the equipment chassis
from power line ground at RF frequencies
