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 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.

CN...K2 types with silver-platinum terminations
(AgPt) suitable for reflow lead-free soldering.
V/I characteristics and derating curves
V/I and derating curves are attached to the data sheet.
The curves are sorted by V
