Metallized Paper (MP) RFI-Capacitors Class Y2 with Internal Series Connection
PCM 15 mm to 27.5 mm

 
Special Features

Particularly high reliability against active

and passive flammability
Twice the safety by internal
series

connection
High degree of interference suppression

due to good attenuation and low ESR
For temperatures up to +110°C
According to RoHS 2002/95/EC

Typical Applications

Class Y2 RFI applications to meet EMC regulations
Capacitors connected to the
mains

between phase or neutral and earthed

casing
By-passing of the basic or supplementary

insulation, pulse peak voltage < 5 kV

Mounting recommendation   Packing
To minimize or avoid shock and/or vibration stresses to terminating wires and solder connections we recommend to fix voluminous resin-potted MP capacitors as from e.g. PCM 22.5mm in an appropriate way since for constructional reasons they do not sit tight on the board.   Available taped and reeled up to and including PCM 22.5mm

Detailed taping information:


Example for ordering / Part number:

* If safety-approved EMI suppression capacitors are operated with a DC voltage being above the specified AC voltage rating the given approvals are no longer valid (DIN EN 60384-14).

 

Furthermore the permissible pulse rise time du/dt (Fmax.) will be subject to a reduction according to

 

Fmax. = Fr x x UAC / UDC

 

if the DC operating voltage UDC is higher than x UAC
