• Manufacturer Part Number: 238167397301
• Description: Twin Vertical Smd 600 V Ptc Thermistors For Telcom Overload Protection
• Manufacturer: Vishay

SOLDERING CONDITIONS
This SMD thermistor is only suitable for reflow soldering. 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 10 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.
