Snubber MKP Capacitors for Pulse Applications with
Double-Sided Metallized Electrodes, Schoopage Contacts
and Internal Series Connection
Special Features Electrical Data
˜ Pulse duty construction
˜ Self-healing
˜ Particularly reliable contact-
configurations: 4-lead versions and
screwable plate connections
˜ Internal series connection from
400 VAC
˜ Very low dissipation factor
˜ Negative capacitance change
versus temperature
˜ According to RoHS 2002/95/EC
Typical Applications
For high pulse and high frequency
applications requiring extremely
reliable contacts e.g.
˜ IGBT-applications

Encapsulation:
Solvent-resistant, flame-retardant plastic
case with epoxy resin seal, UL 94 V-0
Terminations:
Tinned wire or plates.

Mounting Recommendation
Excessive mechanical strain, e.g. pressure
or shock onto the capacitor body, is to be
avoided during mounting and usage of
the capacitors. When fixing the plates the
screw torque is to be limited to max. 5 Nm.
Packing
Transportation-safe packing in
cardboard boxes.
