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.
MOUNTING
With a flat pick-up area = 30 mm
2
the PTC thermistors are
suitable for processing on high speed automatic insertion
equipment.
Typical soldering
235 °C, duration: 5 s (Pb-bearing)
245 °C, duration: 5 s (Lead (Pb)-free)
Resistance to soldering heat

TWIN Vertical SMD PTC Thermistors
For Telcom Overload Protection
SOLDERING CONDITIONS
This SMD thermistor is only suitable for reflow soldering, in accordance with JEDEC J-STD-020. Soldering processes which can
be used are reflow (infrared and convection heating) and vapour phase. The maximum temperature of 260 °C during 10 s should
not be exceeded and no liquid flux should be allowed to reach the ceramic body.
Typical examples of soldering processes that will provide reliable joints without damage, are shown below.

HANDLING PRECAUTIONS
Because of the nature of PTC ceramic material the component should not be touched with bare hands, as the residue of
perspiration can influence component behaviour at high temperatures.
Handling forces applied to the centre of the component should be limited to 20 N vertically and 5 N horizontally in non-soldered
condition. These forces should not be exceeded during the handling, transportation and packaging of the soldered product.
