High-Performance Filter Series FN 9262 (with fuse holder) and FN 9266 (with dual pole switch)
The high-performance filter series FN 9262 (with fuse holder) and FN 9266 (with dual pole switch), are developed for applications demanding high attenuation performance. These represent an enhanced version of the already market proven FN 9260 and FN 9264 filter families. One of the key applications for this filter is the medical market; the filter carries additional approvals, making it easier for the end user to implement into their design. FN 9262 B and FN 9266 B (B-types) filters meet the insulation requirements according to IEC 60601-1 1MOPP (1 means of patient protection).
Both filter series outperform the already existing filters FN 9260 and FN 9264 over the whole frequency range. This increased performance lies in two key components: the advanced core material (common mode performance) and the increased X-capacitor values (differential mode performance).
The housing dimensions are identical to the existing series making an exchange between the filters easy. In addition, the PEMs (Power Entry Modules) are mechanically compatible with almost all similar style products in the market and the same as in FN 9260 and FN 9264.
With the new variant diversity (FN 9260/2/4/6) and the present attenuation properties, this filter family offers a solution for medical devices, modern appliances for household, audio and video. They can also be used in several other applications with similar requirements.
The filters have all the required safety approvals (UL 60939-3, CSA C22.2 No. 8, IEC 60939-3 and CQC), they carry a CE mark and are compatible with the RoHS II (2015/863) directive.
