Design
Multilayer technology
Lack of plastic or epoxy encapsulation for
flammability rating better than UL 94 V-0
Termination (see “Soldering directions”):
 CT types with nickel barrier terminations (AgNiSn),
recommended for lead-free reflow and wave
soldering, and compatible with tin/lead solder.
 CN types with silver-palladium terminations
(AgPd) only suitable for reflow and wave soldering
with solder on tin/lead basis and for adhesive
glueing.
V/I characteristics and derating curves
V/I and derating curves are attached to the data sheet.
The curves are sorted by VRMS and then by case size,
which is included in the type designation.
