Film capacitors are a class of capacitors commonly used for electronic applications. The ECQ-E647KFW is a series of capacitors manufactured by Panasonic, which are based on film dielectric technology. These capacitors come in a wide variety of shapes, sizes, and dimensions, and are able to meet a wide range of electronic requirements.

The ECQ-E647KFW series of capacitors feature their signature high-performance polyethylene naphthalate (PEN) film that is highly reliable and heat-resistant. This ensures that these capacitors have better temperature stability and performance, even in extreme temperature ranges. Additionally, this film dielectric is also especially resistant to mechanical shock, vibration, and moisture infiltration, allowing for greater robustness across environments.

The ECQ-E647KFW series also feature a two-piece case design. This allows for better thermal performance, which helps the capacitor to dissipate heat more efficiently. This is especially important for electrolytic capacitors, which commonly generate more heat due to their greater capacitance. Furthermore, this two-piece case design also allows for easier installation, as it requires less mounting space than single piece cases.

The main application of the ECQ-E647KFW series of capacitors is in power supplies, where they are used for filtering, smoothing, and stabilizing the voltage. Due to its high temperature stability and robustness, this series of capacitors is popular in high power applications, where it helps to reduce ripple effects and provide clean power. Additionally, these capacitors can also be used in automotive applications, instrumentation, and audio/visual equipment.

The working principle of the ECQ-E647KFW series is fairly simple. When a voltage is applied across the terminals of the capacitor, an electrical field is created between the layers of the film covering the plates. This electrical field causes opposite charges to build up on the plate surfaces, resulting in a capacitance. The amount of capacitance can then be modified by changing the size and shape of the plates, as well as the dielectric material used to cover them.

In summary, the ECQ-E647KFW series of capacitor by Panasonic is a reliable and high-performance series of film capacitors. These capacitors feature a two-piece case design for improved thermal dissipation, and their PEN film dielectric is highly resistant to temperature and environmental stress. The ECQ-E647KFW capacitors are commonly used in power supply applications, for filtering, smoothing, and stabilizing voltage. The working principle behind these capacitors is fairly straightforward, as it relies on the creation of an electrical field between layers of film covering the plates, resulting in a capacitance.
