Maximum leakage current,each line-to-ground
@ 120 VAC 60 Hz:
The HQ series power line filters provide the highest
available common-mode and differential-mode attenuation
to RFI noise in the frequency range from 10kHz to 30MHz,
for IEC 60601 and UL2601 patient-connected equipment,
as well as all other electronic equipment that cannot
tolerate any leakage current.

They are a size- and more cost-effective solution to the
problem of meeting both medical leakage current limits and
conducted emissions limits in equipment with high noise
sources (such as switching power supplies). HQ series
filters can help meet the following Conducted Emissions
