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...

## Pricing

- **Price:** $1.95 (inc GST) — $1.77 AUD, exc GST
- **Quantity discounts:** 10+ $1.72 (exc GST) · 50+ $1.68 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA1493:1` (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/ADA1493:1.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 extra-tall extra-small mini heat sinks are easy to use and give you an extra thermal boost.
 
 The heat sink is a 0.25" x 0.25" (6.5mm x 6.5mm) square with 9 tall 'fins' sticking out the top. The total height is 0.5" (12mm) but you can easily file it down if you need a shorter heat sink to fit in a case). Simply use thermal tape or a small amount of thermal paste to attach to the top of any flat chip. There is no thermal tape included with this product. 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 40-50ºC/W

## Technical Details

- Dimensions: 6.5mm / 0.25" x 6.5mm / 0.25" x 12mm / 0.5"
- Weight: 0.6 g
