Film capacitors, or film dielectric capacitors, are electronic components with capacitor construction, utilizing a thin plastic film as the dielectric material and metal electrodes. They are widely used in household appliances, lighting fixtures, motor starters, solar inverters, battery chargers, medical equipment, aerospace and other industries.

The ECW-FD2J335J is a film capacitor manufactured by KEMET Electronics. It is an advanced, two-layer, dipped-film capacitor that is ideal for high-frequency and high-efficiency applications. This capacitor is designed with an extended foil structure which helps to reduce ESL and ESR while improving switching performance at high frequencies.

The ECW-FD2J335J capacitor is suitable for high-frequency switching power supplies and ripple filters with a range of AC and DC power supplies. It is widely used in power supplies for USB chargers, LCD-TVs, solar inverters and PDAs. It also has a low mounting height and a wide range of operating temperatures, making it suitable for various space-constrained applications.

The working principle of this film capacitor is based on the principles of electrostatics and dielectric permittivity. When a voltage is applied between two conductors of opposite charge, an electrical field is created. This electrical field can be used to store energy in the dielectric medium between the two conductors. The capacitance of this dielectric medium is determined by its dielectric constant and the distance between the two conductors. As the voltage increases, the electrical field between the two conductors increases, resulting in an increased capacitance.

The ECW-FD2J335J also has a minimum capacitance of 0.033uF, a maximum capacitance of 0.22uF, and a rated voltage of 25V DC. It has a dielectric strength of 2.0 kVac, a tangent loss at 100kHz of 0.4% maximum, and a temperature coefficient of 83PPM/°C maximum. It is made of a thermoset dielectric material and has an operating temperature range from -55°C to +125°C.

The ECW-FD2J335J film capacitor is a reliable and efficient device that offers superior performance in a variety of electronic applications. It is an ideal choice for power supplies, ripple filters, and other high-frequency switching power supplies. It has a low mounting height and wide range of operating temperatures, making it suitable for space-constrained environments. The extended foil structure helps to reduce ESL and ESR while improving switching performance at high frequencies.
