3. Film Capacitors: Film capacitors are non-polarized capacitors that offer excellent stability and low distortion. They are typically used in audio filter circuits and motor starters, and are available in polyester, polypropylene, and polystyrene types. 4. Tantalum Capacitors: Tantalum capacitors have a high capacitance-to-volume ratio and
How is Film Capacitor different from Electrolytic Capacitor and Ceramic Capacitor? 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
Film Capacitors. Film capacitors are made with thin plastic film and are used for their reliability and low inductance in high-frequency applications. Their construction offers better tolerance and stability compared to other types.
Because of the characteristics of each capacitor, the corresponding application is different. Let''s compare the differences and characteristics of several types of capacitors and summarize how to choose
Along the way I will talk about three popular capacitor types, the film capacitor, the ceramic capacitor and the electrolytic capacitor and explain which one is best suited for which application and why. Let''s get started! More information can be found here: Products used: Capacitors; Further information: Application Notes; ABC CatalogueCapacitors
There are multiple types of film capacitors, including polyester film capacitors and polypropylene film capacitors. Polyester film capacitors are ideal for applications which require moderate precision, like timing circuits. Polypropylene film capacitors have great stability and low dielectric losses, making them the perfect option for high
Film Capacitors. Film capacitors, as the name suggests, use thin plastic film as a dielectric. These types of capacitors are cheap, very stable over time, and have very low self-inductance and equivalent series resistance
There are multiple types of film capacitors, including polyester film capacitors and polypropylene film capacitors. Polyester film capacitors are ideal for applications which require moderate precision, like timing circuits. Polypropylene film capacitors have great stability and low dielectric losses, making them the perfect option for high-performance applications,
Ceramic and film capacitors are the fundamental types used for Class X and Class Y capacitors. Ceramic capacitors provide higher capacitor values in a smaller volume, and are usually selected for low-power
Three common options—multilayer ceramic capacitors (MLCCs), film, or aluminum electrolytic—offer advantages and disadvantages, and there are myriad variations within each category. Choosing the right type ensures the final product has enough energy storage, fits in the available space, and functions reliably for its intended use.
When selecting a film capacitor, it is important to distinguish between leaded and surface mount devices. Leaded (or through hole) capacitors have wire leads which extend from the device. These wires must be soldered onto a circuit board or other device to make a connection.
This Product Selection Guide contains information to help select products in the Film Capacitors category on DigiKey . Film capacitors are based on the use of plastic film materials as a dielectric. An electrostatic (non-polarized) capacitor type having generally favorable parameter stability and loss characteristics relative to other types
Ceramic and film capacitors are the fundamental types used for Class X and Class Y capacitors. Ceramic capacitors provide higher capacitor values in a smaller volume, and are usually selected for low-power applications because of their smaller size. Film capacitors exhibit self-healing capability (see above section on EMI/EMC capacitors
There are multiple types of film capacitors, including polyester film capacitors and polypropylene film capacitors. Polyester film capacitors are ideal for applications which require moderate precision, like timing circuits.
Metallized vs. Film/Foil Construction. Here''s how to choose. For a metallized film capacitor, the capacitor plates are aluminum sprayed onto the dielectric film by thin-film vacu-um deposition. Compared to making the capacitor with sep-arate foil and film sheets, met-allizing enables smaller size, lighter weight, lower cost per microfarad and
They are often used as decoupling capacitors. If you have any special requirements like low tolerance, high reliability, or a capacitor that is able to operate under high temperatures, then choose a film capacitor. It is much better for this. Film caps can be made of polystyrene, polycarbonate, or teflon. They each have their own properties
4. Film Capacitors: Film capacitors are known for their excellent stability, low dielectric losses, and high reliability. They are used in timing circuits, filtering, decoupling, coupling, motor run capacitors, and high-frequency
Film Capacitors. Film capacitors, on the other hand, are known for their excellent frequency response and high stability. These capacitors use a thin layer of insulating material, such as polyester or ceramic, to separate the electrodes. Film capacitors are often used in audio applications that require precise frequency response, such as in equalization circuits
Film capacitors are used in electromagnetic interference (EMI) suppression and as safety capacitors (Classes X and Y). While ceramic capacitors offer better dv/dt capabilities, film capacitors are good (with a
The best choices for snubber capacitors are class 2 ceramic capacitors and metal or plastic film capacitors. Film capacitors are selected because of their low self-inductance, high peak current and low ESR, which are all critical factors in a snubber design. Polypropylene film capacitors are often used in snubber circuits.
The most widely used types of film capacitors include polyester, polycarbonate, polystyrene, polypropylene, polysulfone, and Teflon capacitors. A comparison chart of various film capacitors is shown in Table 1.
Film capacitors are used in electromagnetic interference (EMI) suppression and as safety capacitors (Classes X and Y). While ceramic capacitors offer better dv/dt capabilities, film capacitors are good (with a maximum value of 2200 V/µs) making them suited for use in snubber circuits.

When selecting a film capacitor, it is important to distinguish between leaded and surface mount devices. Leaded (or through hole) capacitors have wire leads which extend from the device. These wires must be soldered onto a circuit board or other device to make a connection.
Film capacitors are also known as plastic film, polymer film, or film dielectric capacitors. Film capacitors are inexpensive and come with a nearly limitless shelf life. The film capacitor uses a thin dielectric material with the other side of the capacitor metalized. Depending on the application, the film capacitor is rolled into thin films.
Polyester film capacitors are ideal for applications which require moderate precision, like timing circuits. Polypropylene film capacitors have great stability and low dielectric losses, making them the perfect option for high-performance applications, such as audio equipment.
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.
In both cases the capacitors should have low leakage current and have adequate precision. The best choices for feedback capacitors are class 1 ceramic capacitors, polystyrene film capacitors, and for high temperature applications, polycarbonate film capacitors.
Advantages of this technology include higher voltage ratings, linear capacitance change with voltage and temperature, no piezoelectric noise, self-healing capability, and long life. There are several categories of film capacitors that can impact which is right for an application:
