Film capacitors are the oldest capacitors in the electrical industry. They are widely used in almost all electrical and electronic equipment. As a critically important component for these devices, what is ECW-H10303RHV? How should we use this item in applications and what’s its working principle? Now, we will provide answers for you.

ECW-H10303RHV has a high-temperature stable and high-precision performance when compared with other film capacitors and ceramic capacitors. It also provides low audible noise, high reliability, and stability & reliability performance. This makes it suitable in an environment of lower temperatures, higher temperatures and moist/damp conditions. Owing to the above features, ECW-H10303RHV has a great number of applications in industries such as telecommunications, automotive, medical and home appliances etc. It can be used in the following conditions:

• Communication systems such as wireless microphones, CDMA / GSM mobile phones, WiFi, satellite TV, radio and television (RF isolation)
• In power supply systems of LCD / LED display, cell phones, digital cameras and portable equipment
• Small medical equipment such as micro blood pressure monitors and glucose meter
• Electronic systems such as mobile phones, computers, frequency conversion electric drive and electronic ballasts

Working principle: The ECW-H10303RHV is made up of three layers: the aluminum foil as an electrode on the top and bottom, and a polyester film as the dielectric in between. These three layers are encapsulated into a crimpable body. When voltage is applied, an electric field is generated in the polyester film. This electric field induces an opposite charge on the opposite electrode. As a result, electrons move through the polyester film, generating current. This aligns the positive and negative charges of the electrodes and leads to electric polarization in the film. The capacitance value of the ECW-H10303RHV is determined by the thickness and size of the aluminum foil and the dielectric constant of the polyester film. It will decrease when too much current passes through the film.

In summary, ECW-H10303RHV with its outstanding capabilities is widely applied to many areas. It is high-temperature stable, offers high-precision performance, has low audible noise, high reliability and stability & reliability performance. In addition, it works well in damp and lower temperatures regions.
