ST-FS6 Ferrite Suppressor / RF Filter
The audio ferrite suppressor / rf filter shall be an RDL ST-FS6. The unit shall provide six individual channels, each comprised of one pair of input and output terminals isolated by wire-wound ferrite cores. Each channel shall be specified for suppression in either an audio or control circuit.  The six channels in the unit shall be capable of operation in either a mic-level or line-level circuit. The unit shall provide two grounding terminals that are electrically isolated from the six channels.

The unit shall be passive and shall not include capacitive components in the signal path capable of altering frequency response or delaying rise-times.  The unit shall not provide an electrical path between any of the six channels.

Each channel shall incorporate ferrite suppression circuitry to reduce the transfer of radio frequency energy through the unit.  Attenuation at 10 MHz shall be greater than 10 dB and greater than 25 dB at 200 MHz.

The unit shall be constructed in an electrically non-conductive, thermally conductive enclosure. Internal circuitry shall be protected from moisture and vibration using a thermally conductive compound that permanently secures the circuitry within the enclosure.

The face of the unit shall provide graphical labels identifying wiring connections.

Connection to external wiring shall be provided using a fixed terminal block on the edge of the unit. The terminal block shall accept wiring gauges from 14 to 22 and shall include a positive electrically conductive mechanism to prevent wire abrasion by the terminal screws.

The unit shall measure 3” (7.6 cm) x 1.6” (4 cm) x 0.7” (1.7 cm) and be compatible with all RDL STICK-ON mounting accessories. The unit shall be supplied with a two part re-closable polypropylene fastener system equipped with a rubber adhesive that bonds to low surface energy materials.

The unit shall passive requiring no power supply. The unit shall be engineered, assembled and tested in the U.S.A. and be specified for continuous duty in professional installed systems. The unit shall be specified for operation in an ambient temperature between -20 and 60 degrees C. The unit shall comply with relevant EMC requirements and shall bear the CE marking.

The unit shall be an RDL ST-FS6.
