FEATURES
• Ideal for pick-and-place circuit assembly
• Low mounting height
• Suitable for reflow soldering
• Small ceramic diameter for faster response
• Low heat transfer to substrate
• Flat terminations for stable positioning and good
solderability
• Compliant to RoHS directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
Over-temperature/over-load protection:
• Telecom
- Central office switching (C.O.)
- Subscriber terminal equipment (T.E.)
- Set top box
- Modems
- Cable TV communications
• General industry and automotive
- Low power supplies overload protection
- Data bus protection
DESCRIPTION
The component consists of a high-performance PTC ceramic
disc mounted in a lead-frame for direct soldering onto a
printed-circuit board (PCB) or substrate.
The ceramic is soldered to the leadframe by a local reflow
process, during which the solder layer is melted to the
metallized ceramic surface using a low residue flux.
MARKING
• All SMD PTCs are marked with the last 3-digits of the type
number (XXX) and a date code (YYWW)
