- Courier delivery nationwide or branch pickup options
Example: Calculating Bulk Heatsink Needs in SA
Suppose you're assembling 100 amplifier PCBs using TO-220 MOSFETs. Each MOSFET dissipates roughly 2.5W during normal operation. To keep junction temperature under 85 degreesC with an ambient of 35 degreesC, calculate the required heatsink thermal resistance:
Formula: (Tj-max - Tambient) / Power = Total R
(85 degreesC - 35 degreesC) / 2.5W = 20 degreesC/W
So, select a bulk-pack TO-220 heatsink with <=20 degreesC/W per part (allowing some margin), and multiply the pack count (e.g., 100 or 120 for assembly overruns).
