I made my own Capacitor at CHEMI-CON!

✅Thank you for sponsoring us, Nippon Chemi-Con! Technical note about the use of aluminum electrolytic capacitors (must-read) https://go.chemi-con.co.jp/l/894001/2023-10-20/6lbttf Tools including SPICE models and a capacitor life estimation tool https://go.chemi-con.co.jp/l/894001/2023-10-20/6lbttm Previous video https://youtu.be/MAP-VA1m-A4 To create my own electrolytic capacitors, I visited Nippon Chemi-Con's Kanagawa Research Center . I performed many processes I had never experienced such as etching, forming, and winding of aluminum foils for capacitors. How is the performance of my hand-wound capacitors going to be? ◤Contents◢ 00:00 Opening 02:10 【Preprocessing】Wash Aluminum Foils 03:19 【Etching】Extend Surface Area of Aluminum Foils by Etching 04:28 【Formation】Form Dielectric Layer on Surface of Aluminum Foils 05:58 【Foil Slitting】Slit Aluminum Foils into Product Size 07:18 【Lead Connecting】Attach Lead Wires on Aluminum Foils 08:24 【Winding】Wind Aluminum Foils Manually 09:38 Attach Rubber Seals 09:59 【Electrolyte Preparation】Mix Materials of Electrolyte 11:19 【Impregnation】 Impregnate Electrolytic Capacitor Elements with Electrolyte 12:15 【Sealing】Put Electrolytic Capacitor Elements in Cases 12:29 【Reforming】Put Capacitors in Constant Temperature Bath to Repair Damaged Elements 14:02 【Sleeving】Wrap Aluminum Cases with Sleeves 14:40 【Performance Test 1】Measure Capacitance of Handmade Capacitors 16:36 【Performance Test 2】Test Capacitors in a Module 19:59 Ending Twitter: https://twitter.com/ichiken_make ■Business inquiries [email protected] https://twitter.com/ichiken_make
