    Hello,

    I am in need of thermal conductive/electrical isolation pads for mounting my TO-220 ICs to a heatsink. I have the thermal grease, but was not able to find the pads at the store. Searching around at other stores, I found this to be a trend. We don't have Radioshack north of the border any more.

    I might just stick with Digikey/Mouser but was wondering which type the average consumer might go for as there seem to be a whole selection of materials and thicknesses to choose from. Also, store recommendations would be great if there are any!

    Thank you,
    JP

    The last pad I bought came from Digi-key. I had looked around a fair amount and that's where I ended up. Your mileage may vary.

    I am surprised I have not come across kits or packages that include the pads/sheets with the bolts and bolt insulator...

    I can't be the only person who finds this somewhat inconvenient... haha...

    *EDIT*

    Just curious of what others are using.

    I found two:

    Aavid Thermalloy - 4880G - $2.89 CAD
    http://www.digikey.ca/product-detail/en/4880G/HS417-ND/1625654

    Keystone Electronics - 4724 - $2.55 CAD
    http://www.digikey.ca/product-detail/en/4724/4724K-ND/109792

    Seems rather pricey... for just one set though.
