1. Is a film capacitor AC or DC?
AC, DC
Film capacitors can be used in both AC and DC circuits. According to the current type, film capacitors can be divided into DC film capacitors and AC film capacitors.
DC film capacitors
DC film capacitors are mainly used in DC circuits and have the following characteristics:
Large capacity: has a higher capacitance.
Low withstand voltage: the withstand voltage value is relatively low.
Polarity: has positive and negative poles.
Application scenarios: commonly used in motor drives, uninterruptible power supplies (UPS), solar inverters, electronic ballasts, small automotive motors, household appliances, etc.
AC film capacitors
AC film capacitors are mainly used in AC circuits and have the following characteristics:
Small capacity: relatively small capacitance.
High withstand voltage: high withstand voltage value.
Pass AC, block DC: conduct electricity in AC circuits, equivalent to open circuits in DC circuits.
Application scenarios: widely used in industrial AC power supplies, asynchronous motor starting and operation, uninterruptible power supplies (UPS) and output filters of photovoltaic inverters, etc. -
2. What is a paper film capacitor?
Paper film capacitors are actually a conceptual error because "paper film capacitors" are not a standard type of capacitor. Based on the information provided, you may want to ask about paper capacitors and film capacitors.
Paper capacitors
Paper capacitors are capacitors that use paper as a dielectric. It consists of thin paper as the dielectric and aluminum foil as the electrode, which is wound into a cylindrical shape and then impregnated with a shell or epoxy resin. Paper capacitors have the following characteristics:
Low cost: Paper capacitors are usually low-cost and suitable for mass production.
Large loss: Due to its material properties, paper capacitors have large losses.
Application scenarios: Mainly used for bypass, coupling, filtering, etc. in low-frequency circuits. -
3. Can film capacitors be used for AC?
Yes
Film capacitors can be used for AC. Film capacitors can work normally in AC circuits and have specific application scenarios and advantages.
Structure and working principle of film capacitors
Film capacitors are mainly composed of metal foil (or foil obtained by metallizing plastic) as electrode plates and plastic film as dielectric. Common plastic films include polyethylene, polypropylene, polystyrene or polycarbonate. These capacitors are usually made by winding or stacking processes to form a cylindrical structure. -
4. What are the alternatives to film capacitors?
CL21 capacitors, MPB capacitors, CBB13, CBB81, MMKP82 capacitors
Alternatives to film capacitors mainly include CL21 capacitors, MPB capacitors, CBB13, CBB81 and MMKP82 capacitors. These alternatives have their own advantages and disadvantages in performance and applicable scenarios, and the specific choice depends on specific needs.
CL21 capacitors
CL21 capacitors and CBB22 capacitors can replace each other in applications such as filtering. CL21 capacitors are more stable than CBB22 capacitors under high-frequency conditions, so CL21 capacitors are more preferred in high-frequency circuits. However, CL21 capacitors are more expensive and perform better in high-frequency circuits.
MPB capacitors
MPB capacitors are boxed metallized polypropylene film capacitors with the same core as CBB22 capacitors, but with a plastic shell, which has better resistance to high temperature, moisture and sealing performance. MPB capacitors can replace CBB22 capacitors in high frequency, DC, AC and pulse high current applications, but their prices are relatively high.
CBB13, CBB81 and MMKP82 capacitors
These capacitors have a higher voltage resistance, up to 3000V, and are suitable for applications requiring higher voltages. However, they are also relatively expensive and larger in size.
