Default Thermistor 1A-1

Evening,
I've been hunting the web but cant seem to find any thermistor 1A-1, or what its value is.

Anyone happen to know what the actual thermistor values / type is? then i can see if I can see if I can get some from Farnell or RS etc

Many Thanks

According to a post in the link below it's 200k (+-20%) cold and 500 Ohms at 100mW dissipation:

I have bag with some in, marked with a BT part number. I remember they were very high resistance at 20C.
Will try and find them and report back.
Not sure if I offered them with my R53, RA53 etc a few months ago. But think all those threads have now gone.

I found some of my Thermistors 1A-1 - now been sent to eBay since I went to the bother to search them out, so Rob may be a better bet!

Thank you for the replies. I'll have a look and see if anything is similar to the one mentioned can be got from electronic suppliers.
I potentially only need one, although I'm beginning to think it is a slight fault with the dial, that causes the bell to tinkle while dialling. none of my others do.

Cheers
Dan

Found them, number is 1A, not 1A-1. Whether mine are first issue, non encapsulated. The 420700 is I believe the stores item number.
Pm me with your address and I can post.
