Film capacitors are a type of capacitor that utilizes a thin dielectric film as the electrical insulator. The dielectric film material of film capacitors can be a polyester, polypropylene or polycarbonate . In general, film capacitors are constructed with electrodes of aluminum foils, multiple layers of film, and two outer metalized-polymer films. The ECW-H20302RHV is a film capacitor specifically that fits in the field of consumer electronics.

The ECW-H20302RHV is designed to offer stable electrical performance across a wide temperature range and is highly reliable. This capacitor has excellent frequency characteristics, high current capacitance, tight voltage tolerances, and low ESR and ESR deviation. It is ideal for AC input rectifier filtering, power management, resonator coil filters, and capacitive divider applications. In addition, it is RoHS compliant and meets the needs of many modern electronic products.

The ECW-H20302RHV capacitor offers an impedance of 30kV/m, a solderability of 260°C, a capacitance of 0.037μF, a voltage rating of 300V, and a capacitance tolerance of 5%. This film capacitor is available in sizes of 10.5mm × 6mm × 11.5mm and has a maximum, rated operational temperature of 125°C. The capacitor is manufactured to dramatically reduce losses caused by dielectric absorption while providing capacitance stability at high frequencies.

The ECW-H20302RHV uses a metalized film capacitor construction. This means the metallized film electrodes of the capacitor are connected to the dielectric instead of being connected directly to the main body of the capacitor. This improves the initial and long-term performance of the capacitor by significantly reducing the amount of contact resistance between the dielectric and the metalized film electrodes. As a result, the ECW-H20302RHV is able to offer better electrical characteristics than other standard film capacitors.

The working principle of the ECW-H20302RHV film capacitor is relatively simple. When a voltage is applied to the terminals of the capacitor, the film electrodes between the two metals become polarized. The film then acts as an insulator, preventing the flow of current to the dielectric and allowing current to flow only in one direction. This directly affects the capacitance or ability of the capacitor to store electrical charge. As the voltage between the two terminals increases, the dielectric’s capacitance increases. On the other hand, if the voltage difference between the two terminals decreases, the capacitance of the dielectric decreases as well.

In conclusion, the ECW-H20302RHV is a versatile film capacitor ideal for a wide range of high frequency applications. It is highly reliable due to its metalized film construction and offers excellent electrical characteristics. The ECW-H20302RHV is also RoHS compliant and can be used in many consumer electronic applications.
