Q Series
This series of RFI power line filters has been developed
specifically for switching power supplies and is designed to
be all the power line filtering needed to control conducted
emissions
all the way down to 10kHz.
High attenuation is
provided for both common mode and differential mode
interference throughout the frequency range with no
degradation of performance due to the large peak currents
drawn by switching power supplies.
These filters are an ideal choice for applications that must
meet emission limits below 150kHz, as well as the
mandated limits above 150kHz. In most cases they will
bring such equipment into compliance with the B-level
limits of CISPR 22. They are also well suited for bringing
ISM equipment (such as ultrasonic cleaners) into
compliance with the limits of FCC Part 18, from 10kHz to
30MHz.
The EQ models meet the very low leakage current
requirements VDE portable equipment, and (120 Volt)
UL544 non-patient medical equipment. The VQ models
offer higher common mode performance at the expense of
higher leakage current, but still meet the leakage current
limits of UL, CSA, and VDE non-portable equipment.
