SOLDERING CONDITIONS

This SMD thermistor is only suitable for reflow soldering, in accordance with JEDEC J-STD-020D. Soldering processes

which can be used are reflow (infrared and convection heating) and vapor 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 a soldering processes that will provide reliable joints without damage, are shown below.

MOUNTING CONDITIONS

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 behavior at high temperatures.

Handling forces applied to the component should be limited to 5 N in any condition.
