DESCRIPTION

Maximum voltage

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.

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 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 a soldering processes that will provide reliable joints without damage, are shown below.

HANDLING PRECAUTIONS

The special leadframe construction and the applied processes do not allow high handling forces on the component.

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 vertically applied to the centre of the component should be limited to 5 N in the non-soldered condition and to

10 N in the soldered. These forces should not be exceeded during the handling, transportation and packaging of the soldered

product.

For those applications where higher handling forces can be present, a reinforced version is available on request.
