## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA1515:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA1515:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

If you want to heat sink a SoC, motor driver, linear regulator, FET or other surface-mount package part, you might find yourself struggling to find a good heat sink. These little extra-small mini heat sinks are easy to use and give you an extra thermal boost. They're also a great deal, you get a pack of 10 in each order!
 
 The heat sink is a 0.25" x 0.25" (6.5mm x 6.5mm) square with 9 little 'fins' sticking out the top. The total height is 0.15" (3.65mm) so it will fit in any case or enclosure. They even come with a bit of thermal tape already on the bottom! Ideal for medium flat BGAs, TSSOPs, QFNs, etc!
 
 we do not have a datasheet for these heat sinks, but Adafruit believe the thermal resistance is approximately 90ºC/W
