Film Capacitors

EMI suppression capacitors, as the name implies, are used to reduce electromagnetic interfer-ence. They are connected directly to line and are therefore exposed to overvoltages and tran-sients, which could damage the capacitors. For this reason, EMI suppression capacitors must comply with the requirements of the following safety standards:

6 FAQs about [Capacitor Interference]

Can radio interference suppression capacitors be used in a mains application?

Before radio interference suppression capacitors can be used in a mains application, they must fulfil safety standards defined by national authorities. The basic world standard for these components is the IEC 60384-14 (ed.3).

Are X and Y capacitors effective against asymmetrical interference?

X capacitors connected between the line phases are effective against symmetrical interference (differential mode). Y capacitors connected between a phase and neutral (zero potential) are effective against asymmetrical interference (common mode). The series B3293* and B3292* H/J are enhanced X2 series for severe ambient conditions.

What are EMI suppression capacitors?

EMI suppression capacitors, as the name implies, are used to reduce electromagnetic interfer-ence.
