6 FAQs about [How to distinguish true and false film capacitors]

What is the difference between film capacitors and ceramic capacitors?

The first difference which is quite evident between these three capacitors is the type of dielectric used and their construction. While the film capacitors use thin sheets of plastic films, ceramic capacitors have sheets made out of ceramic material as the dielectric. Both of them are bipolar in nature.

Are metallized film capacitors affected by DC bias?

Metallized film capacitors are not affected strongly by DC bias. Their volumetric efficiency is not as great as that for multilayer ceramic chip (MLCC) capacitors or electrolytic capacitors. These capacitors (as well as ceramics) are used in safety applications for EMI/RFI reduction and safe failure modes.

How do you know if a capacitor is a metalized film or foil?

The type of electrode used determines whether the capacitor is a metalized film or film / foil type. In metalized types, the very thin electrode is evaporated on the plastic dielectric material. The thin metalized electrodes have a thickness of approximately 10 nm to 50 nm.

How do you know if a film capacitor is faulty?

After a few seconds, the multimeter should display the capacitance value or indicate whether the capacitor is faulty (usually with a “low” or “open” symbol). If you’re uncertain about the results, consult a repair manual or technical expert to further diagnose the issue with the film capacitor.

What are the different types of film capacitors?

There are several types of film capacitors including polyester film, metallized film, polypropylene film, polycarbonate film, polytetrafluoroethylene (PTFE, sometimes branded as Teflon) film and polystyrene film. Like all capacitors, metallized film capacitors incorporate metal plates separated by a dielectric.

What is the capacitance value of a film capacitor?

Capacitance Value: T he capacitance value of a film capacitor is expressed in units of farads (F) or microfarads (μF). Typically, the capacitance value is marked directly on the capacitor body, often using alphanumeric codes. For example, a marking of “473” indicates a capacitance value of 47,000 pF, which is equivalent to 0.047 μF.
