DESCRIPTION

The component consists of a high performance PTC

ceramic mounted in a lead frame with lead (Pb)-free tin

plated contacts. The terminations are joined to the Ag plated

ceramic by a high melting solder. The ceramic is covered

with a protective high temperature silicone layer.

MARKING

? All SMD PTCs are marked with a 3-digit type number

(XXX) and a date code (YYWW)
