Specification callouts to check before buying
| Parameter | Why it matters | Typical values |
|---|---|---|
| Thermal resistance (°C/W) | Lower means better heat transfer from component to ambient | 0.5-10 °C/W depending on size |
| Airflow (CFM) | Affects convective cooling when fan-mounted | 5-100+ CFM for small fans |
| Thermal conductivity (W/m·K) | Higher values for pads/pastes conduct heat better | 1-12 W/m·K (pads); pastes vary |
Product compatibility guidance
Match heatsink footprint to the component (SMD/TO-220/TO-247). For SBCs and small modules, low-profile extruded heatsinks plus a small 30-40mm fan often suffice. For power semiconductors, verify mounting hole spacing and use thermal interface compounds rated for expected operating temperatures. Browse product groups on the Communica collections page to compare options and sizes: thermal management devices for electronics.

Selection help, bundles and pricing considerations
When specifying components for a project, consider total heat dissipation (in watts), allowed temperature rise, and available airflow. Communica stocks brands and maker favourites suited to education and prototyping; see the brand index for options: Shop by brand.
Quick calculation example
Estimate required thermal resistance using this simple formula:
Temperature rise (°C) = Power dissipated (W) × Thermal resistance (°C/W)
Example: a 5 W regulator with a max ambient of 40°C and desired junction margin of 25°C requires roughly 25°C/5 W = 5 °C/W total. Allowances must be made for junction-to-case and case-to-heatsink resistances. For small projects a heatsink in the 2-6 °C/W range plus TIM is typical.
Recommended accessory bundles
- Heatsink + thermal pad/paste + mounting clips for quick PCB mounting.
- Fan + grill + screw set for panel or project enclosure cooling.
- Thermal adhesive + applicator kit for permanent mounting of modules.
Stock, logistics and procurement notes for South Africa
Communica maintains local stock in Samrand and can arrange branch collection from Pretoria CBD or Cape Town where available. For larger orders, request a quote and supply VAT details for procurement. Typical small-batch hobbyist purchases in Gauteng (non-special order) often clear same-day; specialised or branded items may carry lead times - check availability or request a quote to confirm lead times and pricing in ZAR.
Troubleshooting and installation tips
- Ensure the mating surfaces are clean; use isopropyl alcohol before applying TIM.
- Avoid over-tightening screws on TO-220 clips which can deform components.
- Use PWM fans and a simple controller for noise vs cooling trade-offs in labs or classrooms.
