Electronic – How to solder a 70 °C (158 °F) thermal / temperature fuse


For my DMX project (schematics is not important), I soldered this temperature fuse which has just two leads (see picture below).

The fuse doesn't work (meaning it does not conduct electricity) … which of course is logical since my soldering station has a minimum temperature of 200 °C (392 °F) (although I soldered it with 350 °C (662 °F), forgetting about this).

But how should I solder this component?

I think those thermal fuses are normally connected using crimp terminals, rather than by soldering.

Even with the heatsinks the other answers mention, it would be much too easy to damage the device while soldering wires to it.
