High Performance RFI Power Line Filters for Medical Equipment

The HT series power line filters provide superior common-

mode and premium differential-mode attenuation to RFI

noise on 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

leakage current.

They are a size- and 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). HT series

filters can meet the following Conducted Emissions

standards:

• European Normalized Standards based on EN55022,

Level A (in many cases, Level B also).

• FCC Part 15, Computing Devices, Class B.

• FCC Part 18, ISM Equipment, Industrial and

Consumer.

Note: When using the models with an IEC connector,

remember that the leakage current of the companion line

cord, GA400, is more significant than that of the filter -

which may disqualify this line cord from use in patient care

applications.

For more information on UL2601, see Appendix C.
