A walk-through of different types of power capacitors that can be used in induction heater applications, ceramic, MICA, various types of film capacitors and extremely large internally water cooled power capacitors are demonstrated. 2 years back I bought a large lot of induction heater capacitors. Buy a 815 KVAr capacitor by contacting me here: https://highvoltageforum.net/index.php?topic=56.0

From all the different teardowns I have done through the time, I have always kept the nicest parts and pieces to use in future projects. These parts are after all free to start with and something like a heat sink is often very expensive from new once you get above the standard sizes for TO-247
