The FN9255 series of RFI filters with IEC inlet C14 or C20 is Schaffner's first inlet defined up to 300 MHz. The dual-stage high-performance FN9255 filter series is an addition to the market-proven FN92xx filter families and is developed for high-frequency applications, even above 30 MHz.
The adaption of the filter housing is done in length only, which means the FN9222, FN9233, FN9244, and FN9255 will fit in the same cutout, allowing to exchange one for another if the performance is not enough with one of the basic models.
The high number of variants includes about 100 different filter types. Amongst those one can find two versions designed for medical applications; one with and one without earth line choke.
The series also features a rear mount version, which includes a press-in nut to allow a reliable assembly without adding up to the chassis of the system.
With variant diversity and the present attenuation properties, FN9255 offers a solution for modern appliances for household, audio, video, and medical devices. They can also be used in several other applications with similar requirements.
The filters have all the required safety approvals (UL 60939-3, IEC 60939-3, and CQC), are marked according to CE, and are compatible with the RoHS II (2015/863) directive.
