ECW-H20272RJV

Film capacitors are passive electrical components that offer reliable and stable capacitance values. They are widely used in a variety of applications ranging from high-frequency filtering, timing circuits, signal coupling, and snubber applications. The ECW-H20272RJV is an example of a high dielectric strength (“Film”) capacitor. This article will discuss the application field and working principle of the ECW-H20272RJV for the purposes of better understanding its use and functioning.

The ECW-H20272RJV is a miniaturized radial-style film capacitor with a long life and high reliability. This capacitor has a rated voltage of 250VAC and a capacitance of 0.01uF. It is construction with each electrode-capacitor element contained in a separate “window” within an epoxy-resin case. The dielectric material used in this film capacitor is made of a combination of polyethylene nonephthalate (PEN) and other materials. This allows for the capacitor to have a high dielectric strength and low equivalent series resistance (ESR). The capacitor has a pinch seal made of a heat resistant material to provide additional protection to the elements and the coil.

The application field of film capacitors such as the ECW-H20272RJV is broad. Common applications include high-frequency AC line filters, high-frequency signal and noise coupling, snubber circuits, and timing circuits. As mentioned before, it has high dielectric strength and low ESR, making it well suited for AC line filters where voltages higher than 250V can be expected. The ECW-H20272RJV is also suitable for timing circuits requiring low impedance and long service life. Another common use of film capacitors is in snubber circuits used to protect devices such as SCRs, transistors, and triacs from transient voltages or other high–frequency noise.

The working principle of the ECW-H20272RJV is much like that of any other film capacitor. The capacitor consists of two electrodes that are isolated from each other and separated by a dielectric barrier. This creates an electric field that stores energy when a voltage is applied across the electrodes. The amount of energy stored is proportional to the voltage, capacitance value, and frequency. As the voltage and frequency increase, the capacitance of the capacitor decreases and more energy is stored. When the voltage is removed, the stored energy is dissipated.

The ECW-H20272RJV is a reliable and long-life film capacitor designed for use in high-frequency applications. It has high-dielectric strength and low equivalent series resistance, making it suitable for AC line filters, snubber circuits, and timing circuits. Its working principle is based on the charge storage abilities of two electrodes separated by a dielectric barrier. This allows it to store energy when a voltage is applied and dissipate it when the voltage is removed.
