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

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 and a date code (YYWW).
