PTC thermistor multimeter imput protection

[sorin]

Where can I buy PTC thermistor for multimeter input protection
Anybody have any idea??
I watched on ebay but nothing appropriate.
I can't buy from digikey or mouser, because the shipping cost to much, around $70
some idea for what Im looking:

And against what do you want to protect ? PTC's are good for long duration overloads. their reaction time is pretty slow. your protection strategy will need more than just a ptc...
or is this for repair ?

You will need a MOV too and fuses

Well where can you buy things from?  PTCs are pretty standard parts, you should be able to get them from any supplier you can actually buy from.

First, thanks for your time!
I designed a 16 bit digital multimeter.
Yes, I know what are PTC thermistor and for what are used.
the MOV and the fuse are used to protect from  occasional overload, the PTC are other thing.
I just ask you,  if is any cheap option to get it.
