Film capacitors are versatile and widely used in all kinds of applications. They are ideal for high voltage, high current, and high-frequency applications. The ECQ-B1H272JF is a film capacitor, also referred to as a plastic film dielectric capacitor, designed for a wide range of applications. This capacitor is designed for AC applications and is constructed with a polyester dielectric material, which has excellent characteristics such as high insulation resistance, long life, small leakage current, good temperature stability, and low ESR (Equivalent Series Resistance).

The ECQ-B1H272JF is a compact-sized capacitor that offers excellent reliability, durability, and performance. It is a metallized polyester film capacitor with a metalized polypropylene film as the dielectric material. This capacitor is designed to be highly resistant to moisture, and its high-temperature class rating of 105°C makes it suitable for even the most demanding applications. The maximum working voltage is 20V and the dissipation factor (DF) is 0.2-0.003, making it suitable for applications requiring high accuracy. The capacitance range of this capacitor is from 0.01 to 4.7uF. The ECQ-B1H272JF has a radial lead configuration which allows a low profile board mountable operation and a variety of mounting holes and leads. This capacitor is also RoHS compliant for environmental protection.

The ECQ-B1H272JF is a film capacitor that has a wide range of applications, such as power supplies, AC motor drives, DC motor drives, IGBT inverters, and UPS systems. It is also used in pulse inverters, solar inverters, medical equipment, appliances, and lighting control. This capacitor can also be used for coupling, noise reduction, and power factor correction. In addition, it features high frequency characteristic, which means the capacitance value does not change significantly with frequency. This makes it suitable for applications such as switching regulators, transformers, and circuit breakerdrives.

The working principle of the ECQ-B1H272JF is based on the combination of two properties of the capacitor: capacitance and voltage. When a voltage is applied across the capacitor, the dielectric material between the two metalized electrodes provides insulation for the charges, resulting in a capacitance. The amount of capacitance is determined by the size of the electrodes and the distance between them. As the voltage across the capacitor increases, the electric field strength between the electrodes also increases, resulting in increased capacitance, a phenomenon known as capacitance voltage effect. This capacitor has a higher capacitance voltage ratio than other kinds of capacitors, such as electrolytic capacitors.

In summary, the ECQ-B1H272JF is a film capacitor that is ideal for high voltage, high current, and high-frequency applications. Its low equivalent series resistances, corrosion-resistant construction, high temperature class rating, and wide range of capacitance make it suitable for a variety of different applications. Its capacitance voltage effect also makes it suitable for applications requiring precision. From power supplies and motor drives to medical equipment and appliances, film capacitors make a great choice for a variety of different applications.
