[sdiy] SMD Tempco Plea for Help

[Ken MacBeth]

My experience of SMD tempcos is that as long they are in the vacinity of the transitor pair, they work fine..........no glue, no contact even.........tell me, are you designing your own pcbs?.............I have tempcos that sit ver near the transistor pair in my oscs.............I think that small-ness actually helps a lot, lesser area to be affectd by the ambient temperature....

Hello everyone,

I ordered some of the Panasonic 805 surface mount tempco from Digi-Key,
and finally received them today. For just over $21, I bought 50 1K
3300ppm tempcos. I had grand dreams of tempcoing every expo converter
I've ever built. Forget just VCOs, I'm tempcoing filters, VCAs,
everything!

So I open the package, and...

Sweet merciful crap, these things are small!

I remember a couple of list members mentioning that they've used the
SMD tempcos, affixing them to 2SC1583s and what have you. What type of
adhesive would be best to stick them on the transistor pair?
Cyanoacrylate emits some nasty fumes when heated (I've learned this the
hard way), so I've just about ruled that out. I'm thinking I might use
wire-wrapping wire to solder to the terminals on the tempco... good
idea? Better suggestions?

Thanks for any suggestions!
