Film capacitors, or plastic film capacitors, are a type of capacitor that use plastic film as the main component of the capacitor dielectric. This type of capacitor construction due to their low cost, high dielectric strength, low ESR, wide frequency response, and long-term reliability has become increasingly sought after in a variety of applications. One such film capacitor used in a range of high power applications is the ECW-H10912JVB.

The ECW-H10912JVB is a DC link film capacitor specifically designed for use in high power voltage converter and inverter systems. This type of capacitor features high energy density, high stable capacity, high protection class (IP00) and wide operating temperature range (-25°C ~ +80°C). Featuring high current handling and high stability, the ECW-H10912JVB is ideal for applications such as in motor drive, UPS systems, power tools, power conditioning systems, welders, electric vehicles and inverter systems. It also features an UL recognised 94V-0 compliant flame retardant plastic cover.

The ECW-H10912JVB is a radial lead capacitor that features a dielectric of metalized polypropylene film. The anode and cathode leads are of tinned copper-clad steel and feature a silver coating to improve solderability. The maximum voltage rating of the capacitor is 800VDC with a rated capacitance of 122uF. The capacitor has a temperature coefficient of ±25% at 90Hz, ±20% at 20kHz and a noise ripple of 8uA.

The working principle of the ECW-H10912JVB is based on the process of ‘charge storage’. In this process, when a voltage is applied, an electric field is defined that causes the positive and negative charges to separate and accumulate in the two separate phases of the capacitor. The voltage applied to the capacitor is what causes the positive and negative charges to separate and accumulate in the two phases of the capacitor. When the voltage is removed, the electric field that was created between the two phases of the capacitor becomes weaker, allowing the accumulated charges to slowly dissipate. This process of charge storage is the basis of operation for all capacitors, regardless of type.

The ECW-H10912JVB is a reliable and durable film capacitor that provides a stable and reliable source of voltage stabilization in a variety of high power applications. Its long-term stability and wide operating temperature range make it an excellent choice for applications in which reliability and precise performance are essential. The ECW-H10912JVB is one of many film capacitors used in various high power applications and is well-suited for applications such as motor drives, UPS systems, power conditioning, power tools and electric vehicles.
