Film capacitors, also known as dielectric film capacitors, plastic film capacitors, polyester capacitors or film-foil capacitors, are one of the most widespread components in the electronics industry. It is capable of providing superior performance stabilities compared to its ceramic and aluminum counterparts because its dielectric provides robustness against mechanical shock, vibration, and thermal shock. The ECW-H8513JL, a part of the surface mount, plastic film capacitor family, has unique application fields and working principles that set it apart from other film capacitors.

The ECW-H8513JL comprises of a three-terminal electrolytic capacitor with its active component being a cylindrical, thin film, non-woven polypropylene dielectric. It has a wide range of capacitance values from 0.1µF to 1500µF with ESR ratings of 0.0052Ω to 1.3Ω (depending on its size and type). Given its operating voltage range from as low as 6.3V to over 450V and a shocking dissipation factor from 20-60mA, it makes it ideal for a variety of uses.

Many industries such as the telecommunications, automotive and aerospace industries rely on the ECW-H8513JL for its versatility and performance. Two key features are the ability of this capacitor to self-heal and its environmental resistance. Self-healing is an aspect of this component that is highly critical in the communications industry, where there is a need for extremely reliable and robust systems. ECW-H8513JL is designed to quickly identify and self-repair minor discontinuities made on the dielectric of the capacitor itself.

Additionally, given its environmentally resilient construction, it is capable of withstanding harsh environmental conditions with high moisture, dust, and temperatures (up to 125°C). The fact that it is compliant to the EU RoHS directive is yet another plus.

The ECW-H8513JL, as compared to film capacitors, implements two layers of dielectric instead of the more traditional single layer. This two-layer system works by having a thin barrier film acting as an anode between a thick sheet of film acting as the cathode. The thinner barrier film, made of materials such as aluminum oxide or quartz, has a very low conductivity, which provides excellent ESR performance. The thicker film is made of a material such as polypropylene, which is known to be a great insulator, providing good capacitance and stability. The two materials are stacked together and then formed into a cylindrical shape.

The two capacitors used in the ECW-H8513JL are in turn wired in series with an inductor, making a parallel LC resonator. This parallel LC resonator allows for the capacitor to run at a very high frequency and still maintain low ESR. The combination of the two capacitors also helps in lowering the ESR over other competing films, such as polyester and aluminum electrolytes.

Aside from its technical features, the ECW-H8513JL has numerous applications such as decoupling, coupling, filtering, and noise-suppressing within the power-supply circuits. It also has an extensive range of adapted uses in medical devices and measuring instruments due to its high precision and reliability.

In conclusion, the ECW-H8513JL is a great example of a robust and reliable film capacitor. Its innovative design and wide variety of applications make it a favorite across many industries. With its vast range of features, it is no wonder why the ECW-H8513JL is increasingly becoming the capacitor of choice.
