High dielectric constant: Metalized polypropylene film capacitors have a relatively high dielectric constant, which allows them to store more charge and have a greater capacitance relative to other capacitors of the same volume.
Low dissipation factor: Metalized polypropylene film capacitors generally have a low dissipation factor, which means they remain efficient and produce little energy loss during the storage and release of electrical energy.
High Temperature Operating Capability: This type of capacitor is capable of operating over a wide temperature range, including high temperature environments, making them suitable for some demanding applications such as automotive electronics and aerospace.
Stability: Metalized polypropylene film capacitors exhibit high stability, can maintain a constant capacitance value, and are not easily affected by external environments or voltage fluctuations, contributing to the reliability of electronic circuits.
Low Leakage Current: Metalized polypropylene film capacitors have low leakage current, which means they leak less charge as they store it, thus improving the performance of the capacitor.
Long life: Relative to some other capacitor types, metalized polypropylene film capacitors generally have a longer life and are able to operate stably in circuits for a long time.
Structure of Metalized Polypropylene Film Capacitor
Dielectric
The core of metalized polypropylene film capacitors is the dielectric, and polypropylene film is usually used as the dielectric material. The dielectric is the insulating material of a capacitor that exists between the two conductive electrodes to isolate and store charge. Polypropylene material has good insulating properties and stable dielectric properties, making it suitable for high-frequency and high-voltage applications.
Conductive electrodes
In the structure of a capacitor, there are two conductive electrodes, usually made of metal foil or metal film. These conductive electrodes are located on both sides of the dielectric film and act as electrodes of the capacitor, forming a capacitive unit together with the dielectric. The charge is stored in the space between the dielectric and the conducting electrode.
Connecting Wires/Leads
Capacitors often have leads or connecting wires that connect the capacitor to other components in the circuit. These leads are usually attached to the conductive electrodes to allow the capacitor to be integrated into the circuit.
Casing/Packaging
To protect the capacitor's internal components and ensure its stability, metalized polypropylene film capacitors are typically packaged in an enclosure. The housing can be made of different materials, such as plastic or metal, to protect the capacitor from mechanical damage and environmental influences.
Markings/Markings
Capacitors often have markings or markings that indicate important information such as their capacitance value, voltage rating, polarity, etc. These identifications assist in the proper selection and connection of capacitors and ensure their proper operation in the circuit.
