6 FAQs about [St Johns capacitor film]
What are film capacitors used for?
Film capacitors are widely used in power electronics applications including but not limited to DC Link, DC output fltering, and as IGBT snubbers.
What is the rated voltage of a film capacitor?
Rated Voltage : 1000 – 5000Vac Ripple RMS Current up to 18A HKFC designs and manufactures Power Film Capacitors and High Voltage Film Capacitors for High RMS Current, High Voltage and 105C temperature applications.
What are the raw materials for capacitor films?
The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.
Why are film capacitors used in DC fltering?
Film capacitors are widely used for DC fltering in power supplies. Their function is to smooth out the DC voltage waveform after rectifcation. As with all switching devices, IGBTs are subjected to voltage transients during turn-of operation. Voltage transients result from energy trapped in the circuit’s stray inductance.
What is a DC FLM capacitor used for?
The most common applications for DC flm capacitors in power electronics are DC Link, DC Filtering and snubbers for IGBT modules. A brief description of each application follows: Large value capacitors are used as the energy storage element or DC-Link at the DC input to the inverter.
What is a metallized capacitor?
Metallized capacitors use a thin layer of vapor deposited aluminum, zinc or alloy (aluminum/zinc) blend as the electrode system. The metallized layer is only hundreds of angstroms thick, so it takes up little space in the capacitor winding relative to the dielectric thickness, measured in microns.
