I want to build a wireless charger for my wireless mouse. I found a nice writeup here.
**broken link removed**
The author used mica caps, but they are expensive.
The question is can I use a film capacitor in place of the mica one or do I need to worry about the dissipation factor in the cap running at 125KHz. ?
