Film capacitors, also known as plastic film dielectric capacitors, are constructed using impregnated plastic films such as polyethylene terephthalate (PET) or polypropylene (PP) as their dielectric layer. They are one of the most commonly used types of capacitor due to their low dielectric absorption, stable electrical characteristics, low cost, and wide range of capacitances.

The ECW-F2274JAB is a polypropylene film capacitor designed for energy storage and energy transfer applications. It is widely used in audio frequency coupling and decoupling circuits, in which its superior high-frequency characteristics are ideal for reducing EMI and RFI noise. It is also used in high frequency power supplies and high frequency transmission systems.

The ECW-F2274JAB is constructed with a polypropylene film coating deposited onto an outer metal sleeve. The polypropylene dielectric layer is very thin, allowing the capacitor to react quickly to changing electrical conditions. Furthermore, the material is an excellent dielectric, resulting in low dielectric absorption and excellent stability over a wide temperature range of -55°C to +125°C. The capacitor also has good ESR and ESL characteristics, making it suitable for high frequency, high power, and high voltage applications.

The working principle of the ECW-F2274JAB is simple. When a voltage is applied across the terminals, it causes electric charges to spread across the dielectric in proportion to the applied voltage. This electric field generates an electric current to flow through the capacitor. As the current accumulates, the capacitor stores energy and delivers it when the circuit needs it. The capacitor can be charged and discharged very quickly, making it ideal for high frequency applications.

The ECW-F2274JAB has a standard operating temperature range of -40°C to +105°C, making it suitable for a wide range of applications. Its high surge current capability also makes it an ideal choice for energy storage and transfer applications. The capacitor is also RoHS compliant and offers high long-term reliability.

The ECW-F2274JAB is a versatile film capacitor suitable for a wide range of applications, particularly energy storage and transfer applications. Its high frequency characteristics, coupled with low dielectric absorption, make it an ideal choice for many industrial, automotive, and consumer applications.
