The VDE, cULus, and CQC certified X2 film capacitors from Wurth Electronics are in the 275 V_AC and 310 V_AC voltage ranges, and guarantee reliable interference suppression for the application. The components are available in 7.5 mm to 37.5 mm pitch up to a maximum of 6.8 μF. Pulse stability extends to 600 V/μs. All types are TÜV tested and are approved according to the relevant UL standard.

Würth Electronics is the only manufacturer to stock film capacitors with two standard pin lengths. The 'CS' suffix refers to short lead capacitors with 4 mm length, which are ideal for production. Parts not containing the 'CS' suffix have long leads (20.0 mm) which are suited to fit prototyping needs.
