Film capacitors are electro-mechanical devices commonly used in electronic circuits. As their name suggests, they are made up of two layers of plastic film, sandwiched together and insulated from one another. The two layers are made of materials that are highly dielectric – meaning they are good at blocking electric fields – so that when a charge is applied to the capacitor, it stores the energy as an electrical field between them. The capacitance of the device—which is the measure of how much charge it can store—is determined by the size and shape of the capacitor’s plates, as well as the dielectric material used.

The ECW-FD2W395JB is a type of film capacitor specifically designed for audio-frequency applications. It is constructed with a polypropylene layer and a polyester film layer, each with its own electrodes. These two layers are connected in parallel, so that the capacitance is doubled while the voltage rating remains the same. This design gives the ECW-FD2W395JB an unusually high capacitance-to-voltage ratio, making it an ideal choice for many audio applications.

Due to its high-frequency construction, the ECW-FD2W395JB is capable of blocking high-frequency interference, while still allowing AC audio signals to pass through without distortion. It also has a very low internal resistance and fast switch-mode operation, making it ideal for use in high-end audio amplifiers, preamps and receivers.

In terms of its working principle, the ECW-FD2W395JB operates similarly to any other capacitor. When an AC voltage is applied to its terminals, the capacitor charges up, blocking any DC component from passing through. As the voltage changes, so does the capacitance, allowing the device to control the current flow and store the energy as an electrical field.

The ECW-FD2W395JB is also highly reliable and durable, with an operating temperature range of -25°C to +85°C and a life expectancy of 5,000 hours at rated voltage. This makes it well-suited for a variety of audio applications, such as wiring power supplies, filtering out high-frequency interference, and protecting audio circuits from harmful voltage spikes.

In summary, ECW-FD2W395JB is an audio-frequency rated film capacitor designed for long-term reliability and high capacitance-to-voltage ratio. It is ideal for a variety of audio applications, including wiring power supplies, filtering out high-frequency interference, and protecting audio circuits from harmful voltage spikes. Its high-frequency construction and fast switch-mode operation make it ideal for use in high-end audio amplifiers, preamps and receivers.
