Film capacitors are capacitors that use an insulating film as the dielectric as in paper capacitors. Usually, the dielectric material consists of a polyester, polypropylene, polyethylene naphthalate, polycarbonate, polystyrene, polyphenylene sulfide, or metallized polyester. The film capacitor technology is characterized by a very wide range of form factors, easy machining, and flexibility of dielectric layers. This makes film capacitors ideal for a wide range of applications.

The UNL7W20K-F film capacitor is a metallized film capacitor with long life, high stability and excellent ripple current handling characteristics. It is available in various sizes and cover a voltage range from 6.3 V up to 630V. The UNL7W20K-F is a special design for general use in DC/AC applications. The electrical characteristics of this capacitor are very good, with a very small leakage current and excellent self-healing properties when subjected to a surge.

UNL7W20K-F capacitors are widely used in power related applications like motor control, power circuits, across-the-line starting, photovoltaic systems, UPS systems and more. As they are designed to provide high stability and ripple current performance they are used widely in frequency detectors, rectifying circuits and other critical components of power systems.

The UNL7W20K-F is a metallized film capacitor, where the two external metal plates of the capacitor are made from an aluminum-zinc alloy. The cores of the metal plates are of a dielectric material such as polypropylene or polyethylene naphthalate, both of which provide excellent performance in terms of dielectric strength and durability. The aluminum-zinc alloy has a very low ESR, which helps reduce losses due to heat dissipation. The combination of the dielectric material and the alloy helps provide superior stability and ripple current handling capabilities.

The UNL7W20K-F is a surface-mount device and is used in applications where real estate is at a premium. As it is a surface mount device, installation is very simple and requires no soldering. It is appropriate for multiple layers of circuits on printed circuit boards and provides superior electrical performance due to its low parasitic inductance.

When considering UNL7W20K-F capacitors for your design, it is important to consider their self-healing properties, their long life, high stability and excellent ripple current handling capabilities. By ensuring that the design takes into account their characteristics, you can be sure that you will get optimal performance out of them. This is especially important in more complex systems such as motor controllers, UPS systems and photovoltaic systems.
