Introduction:

The ECW-FD2J125K is a film capacitor (also known as an electrolytic capacitor) that is used in a variety of applications. This type of capacitor is cylindrical and is made from a thin plastic film impregnated with an electrolyte. Its design makes it a superior choice for applications requiring low leakage current, high insulation resistance, and stable capacitance over temperature and frequency. It is commonly used in RF, power supply, audio, and high-speed signal processing systems.

Applications:

The ECW-FD2J125K is designed to be used in a wide range of applications. It is suitable for use in switching power supplies, signal processing, signal conditioning, and other high-frequency applications. It is also suitable for use in energy storage, DC filters, and other related fields. It is typically used in RF and microwave circuits, where its low leakage current requirements, high temperature stability, and superior capacitance characteristics make it an ideal choice.

Features:

The ECW-FD2J125K is a versatile film capacitor with a combination of features that make it an attractive choice for many applications. It has a low impedance with a low ESR, and its leakage current is low enough for applications requiring superior performance. It is also self-healing, meaning it can will recover from microscopic internal damage without impacting overall performance. Additionally, it is highly durable and long-lasting due to its epoxy addition and nitrogenized polyester film.

Specifications:

The ECW-FD2J125K is designed to meet a wide range of specifications, making it suitable for nearly any application. Its rated voltage is 250Vac and its capacitance range is between 0.1uF to 1000uF. Its capacitance tolerance is +/-20%, and its operating temperature range is between -25°C to +85°C. Additionally, it has a rated ripple current of 0.33 times its capacitance value at 60Hz and a testing voltage of two times rated voltage.

Design:

The ECW-FD2J125K is constructed with a cylindrical body made from a thin plastic film impregnated with an electrolyte. Its electrodes are a combination of metal etched with nitric acid and nickel electroplating. The capacitance element of the ECW-FD2J125K is created via vacuum deposition of metal onto the electrodes. The capacitance element is then wrapped with a nitrogenized polyester film that is further coated with an epoxy resin to protect it from shock and vibration.

Working Principle:

Film capacitors use a dielectric material that acts as a barrier between two metal electrodes. This dielectric material generally consists of a thin plastic film, such as the nitrized polyester that is used in the ECW-FD2J125K. As a current is passed through the capacitor, an electric field is generated that stores energy between the two electrodes. These stored charges act as a charge reservoir, allowing the capacitor to store a temporary electrical charge. When the electric field is removed, the stored charge dissipates and the capacitor ceases to function as a capacitor.

Conclusion:

The ECW-FD2J125K is a film capacitor that is designed for use in a variety of applications, from radio frequency and microwave systems to power supply and signal processing. Its combination of features makes it ideal for high-frequency applications that require low leakage, high insulation resistance, and stable capacitance over temperature and frequency. Its design is engineered for durability, making it an excellent choice for long-term reliability and performance.
