Brands & Selection Guidance

• Ribcon, Fischer Elektronik, and Sunkko for PCB-mounted and custom-cut extrusions
• Generic and own-brand low-cost sinks for hobby, repair, and education
• Check "Power & Thermal Management" and "Shop by Brand" on Communica's site for availability

Choose based on footprint, mounting style, and wattage. Consider pairing with thermal pads or compound for best performance.

How to Order and Match the Right Heat Sink

Selection Criteria: What to Consider

• Device Package: Match to TO-220, TO-3P, or chip profile for secure fit.
• Thermal Resistance: Lower degreesC/W handles higher power - check datasheet maximum junction temperatures.
• Physical Constraints: Consider available PCB/box space and airflow (forced or passive cooling).
• Mounting Hardware: Some sinks require bolts, clips, or adhesive. Check if included or order separately.

Simple Thermal Calculation (South Africa Example)

To select a suitable heat sink, use:

Example

Regulating a TO-220 linear voltage regulator in a Pretoria workshop:

• Ambient: 30 degreesC
• Dissipation: 2.5W (V_drop x I)
• Desired junction rise: <60 degreesC
• Required R_th: (60 degreesC / 2.5W) = 24 degreesC/W - select a 20 degreesC/W sink.
