The ECW-H16912JVB can also be used in professional audio systems, as it has a low voltage coefficient and excellent filtration characteristics. It is also relatively symmetrical when it comes to capacitance & DC resistance, allowing it to be used in high current applications without any major performance issues.

Working Principles

The ECW-H16912JVB is a polypropylene film capacitor which utilizes a metallized film as the core element. The dielectric is made of high-grade polypropylene film, and is then wrapped around the dielectric with metal electrode. This arrangement of components gives the ECW-H16912JVB excellent self-healing properties.

The self-healing property of the ECW-H16912JVB is largely due to its unique design. The metal electrode serves as an effective heat sink, dissipating the energy generated when an arc develops inside the capacitor, neutralizing it. This helps the ECW-H16912JVB maintain its capacitance over a long period of time, even when subjected to arcs and overloads.

The ECW-H16912JVB also features an internally impregnated self-healing polyurethane compound. This compound is found between the dielectric and the metal electrode, and it helps reduce electric leakage currents which can occur over time.

Conclusion

The ECW-H16912JVB is a Wrapped Metallized Polypropylene Film Capacitor, with many unique features that make it great for a variety of applications. Specifically, it is great for power supplies, motor drives, stabilizers, and professional audio systems thanks to its high insulation resistance, low dissipation factor, long life expectancy, low voltage coefficient, and excellent filtration characteristics. It also has an effective heat sink which neutralizes arcs and supports its self-healing properties. Ultimately, the ECW-H16912JVB is a great choice for any application requiring a high-quality film capacitor.
