Film capacitors are a form of electrical storage device composed of thin plastic arcs immersed in liquid electrolyte and foil electrodes. The most popular type is the WMF6P22K-F. This capacitor is designed for use in high temperature and high voltage applications, particularly when exposed to vibration and large fluctuations in temperature and current. This type of capacitor is often used in multilayer ceramic capacitors, surge arresters, snubber circuits and RF power amplifiers.

The components of the WMF6P22K-F are made of a combination of rigid and flexible materials, including an electrical foil, dielectric material, conductive material, and insulation. The foil electrodes consist of a combination of aluminum and titanium to ensure uniform charge distribution. The dielectric material is a combination of high-grade polymers and liquid electrolytes, which is designed to provide superior shock protection in high temperature and high-voltage applications. An encapsulated insulation layer protects the internal components from environmental extremes and helps to maintain consistent and stable capacitance values.

This film capacitor has several features and benefits. It is designed for very low ESR and offers high ripple current ratings, which makes it ideal for use in power supply circuits. The capacitor works to smooth the current waveform, and its dielectric absorbs any high frequency harmonics. It is also immune to voltage transients, thus these capacitors provide protection against line noise. Other advantages include a high energy density, a low self-discharge rate, and increased stability when exposed to high temperatures.

The working principle of the WMF6P22K-F is similar to that of any other form of capacitor in that it functions by storing and releasing electrical energy. When subjected to a fluctuating current, the capacitor works to smooth out the waveform by absorbing and then discharging the electrical energy, thus allowing for the uninterrupted flow of power. In addition, by conducting in both directions, the energy absorbed by the capacitor is dissipated back out into the system.

The WMF6P22K-F is an ideal choice for applications requiring high levels of performance in extreme environments. Its robust design helps ensure that it remains stable in temperatures ranging from -55°C to +125°C and offers excellent protection against transients and harmonics. Furthermore, due to its low ESR, the capacitor helps to reduce losses, providing higher efficiency in power supplies and other applications.
