Film capacitors, also known as polymer capacitors, are generally thin layers of organic polymers sandwiched between two electrodes. These capacitors are used in a variety of applications, including power electronics, consumer electronics, and high frequency applications. WMF1S22K-F is a film capacitor manufactured by Vishay, and it has unique features which make it suitable for various applications.

WMF1S22K-F is a polypropylene capacitor with a capacitance of 0.022 µF, a voltage rating of 1 kVAC/DC, and a temperature range of -55°C to +105°C. It has low dissipation factor, low leakage, and long life due to its robust construction. The capacitor has a maximum ripple current of 0.7 A and a maximum ESR (Equivalent Series Resistance) of 0.75 mOhms.

The WMF1S22K-F is an AC/DC film capacitor with a metallized polypropylene dielectric. The metallized construction ensures low losses, high volumetric efficiency, and high reliability. This capacitor also has a self-healing, fast electrical response, which makes it suitable for power electronic applications.

WMF1S22K-F can be used for a wide range of applications, including power supplies, pulse circuits, resonators, RFI suppression, filters, bypass circuits, inverters, DC link circuits, and more.

The high ripple current rating and low ESR of the capacitor makes it suitable for AC/DC power switching applications. Due to its low losses and long life, this capacitor is also used in long-term high frequency applications.

The working principle of WMF1S22K-F is based on the fact that when an electric current passes through an insulating material, electric charge is stored and builds up on the surface of the material. When the current is switched off, the electric charge starts to decay and a voltage potential is generated across the material. This voltage potential is the capacitor voltage and behaves like a storage battery. The WMF1S22K-F capacitor operates by transferring charge from one electrode to the other when an AC voltage is applied across the capacitor.

The WMF1S22K-F has unique features which make it suitable for various applications. It is a versatile capacitor with a wide range of uses, and can be used in AC/DC applications. It has low losses, high volumetric efficiency, and high reliability, and is suitable for long-term high frequency applications. With its high ripple current rating and low ESR, it is also suitable for power switching applications.
