Sunnex does not recommend any specific filter but the specifications of the Celestial Star product must be
carefully considered when selecting a filter. Some manufacturers that make RF filters are: Amphenol
Canada, Spectrum Control, ERNI, Conec. (Amphenol Canada part# FCC17-A3W3AD-2X0 or equivalent
filter should be used.) The voltage drop over the filter must be minimal to ensure proper performance of the
light fixture. The guidelines and requirements of your MRI facility must be considered as well. Consult with
your MRI facility manager or the RF panel support technician if uncertain.
