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.
Notes
1. Customized products are available on request.
2. Coated and/or reinforced types are available on request.
MARKING
