High hona joale DC link filimi capacitor bakeng sa motlakase drivetrain inverters

Tlhaloso e Khutšoanyane:

1. Sephutheloana sa polasetiki, se tiisitsoeng ka eco-fridendly epoxy resin, copper lead, boholo bo ikhethileng

2. Ho hanyetsa ho matla a phahameng, ho ipholisa filimi ea metallized polypropylene

3. ESR e tlase, bokhoni bo phahameng ba ho sebetsana le ripple hona joale

4. ESR e tlaase, ka katleho e fokotsa matla a ho khutlela morao

5. Bokhoni bo boholo, sebopeho sa compact
