APPLICATIONS
Over-temperature/over-load protection:
• Telecom
-Central Office Switching (C.O.)
-Subscriber Terminal Equipment (T.E.)
-Set-top Box
-Modems
• General industry and automotive
-Low power overload protection
-Inrush current limitation

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)
