Frequently Asked Questions
Q: Benefits of Low Resistance and Low Self Inductance
Two major benefits of film capacitors comes from the fact that they have low equivalent series resistance and low self inductance. Due to these properties, they can be designed to withstand voltages in the kilovolts. Power film capacitors take these benefits even farther and can withstand reactive power over 200 volt amperes in charge. These types of benefits make them very attractive overall to a wide variety of different types of industries all over the world. Constructions costs can be slashed even farther through the use of special materials.
Q: Manufacturing Capacitors to Meet Every Need
Our film capacitor are very specific types of capacitor that uses a thin plastic film as a dielectric element in the configuration. The thin plastic film is made using a technologically advanced film drawing process. Depending on how the capacitor needs to operate when it is finally configured, the thin material may be either left untreated or metalized after the manufacturing process. Once the film material has been added, electrodes are placed into the assembly, which is mounted into a case that is designed to protect the capacitor from a wide variety of different environmental factors. Due to the fact that they are incredibly stable, do not cost a significant amount of money to manufacture and have a low rate of inductance, they are being used in many different types of applications. Buyer beware, there are many different types of capacitors on the Internet that qualify as film capacitors that just change the type of material being used as the dielectric. Our high-quality polymer film capacitors, plastic film capacitors, power film capacitors and more are readily available to meet your needs. The specific type of material that will be used during the creation of the capacitor will vary depending on what the device will end up being used for. Let us know how we can help in meeting your needs and exceeding your expectations.
Q: Plastic Film Capacitors
Plastics come in such a wide range that they can cater to most of our technical needs. They can be used in high-temperature applications (Teflon), power (polypropylene), energy conversion (polyester), and for functions requiring high stability (polycarbonate). The product range extends from capacitor outputs for implementation on printed circuits, to metal housings with terminal output for power capacitors in wired circuits. Surface mounted devices (SMD) and fi lm capacitors withstanding high temperatures are also manufactured.
Q: Do you need High Precision Capacitance Values?
Film capacitors are used in a wide variety of different industry, including with military technology and applications as well as the aerospace industry. This is mainly due to the fact that they have high long term stability, can be produced relatively cheaply and are heat resistant. One of the main characteristics of our film capacitor comes from the fact that they are not polarized. Due to this design element, they are available for use in both AC power and signal applications. They are also designed to have high precision capacitance values, which means that they can retain their value for a much longer period of time than capacitors of other types. The aging process of these types of capacitors is generally much slower than it would be if a different type of material were being used during construction.
