Film capacitors, also known as polyester capacitors, are a type of capacitor that uses polymer film as the dielectric. This type of capacitor is compact, lightweight, and volumetrically efficient. They also provide excellent electrical insulation, and their self-healing characteristics give them a degree of robustness and longevity. The ECQ-U2A104MV is a film capacitor intended for use in AC mains-operated devices. It is designed to provide filtering, decoupling, and signal-conditioning services in an array of applications.

The ECQ-U2A104MV is constructed of aluminum terminations wetted with a metallic passivation layer over a metallized polyester film. The capacitor’s EIA-rated capacitance is 0.1µF, and its operating voltage range is 0-250VAC. In addition, the device’s operating temperature range is from -25°C to 105°C. The capacitor is rated for Class X1 and X2 service indicators, and it meets UL, CSA, and VDE safety standards.

In comparison with electrolytic capacitors, film capacitors have the advantage of greater operating stability and a much higher working voltage. In addition, they are much less prone to failure and require no external voltage to charge before they can be used, meaning they offer a simpler, lower cost solution for many applications. They are also much more tolerant of environmental influences such as humidity, vibration, and shock.

Due to their characteristics, the ECQ-U2A104MV is ideally suited for a range of AC operating voltage applications, including power supplies, energy-saving lighting, and electric motors. Capacity-controlled motors, where the drive voltage is derived from the motor itself, are a particularly common application. The ECQ-U2A104MV is also used in HVAC systems, where its high internal and external insulation can retain the energy required to keep the system running efficiently.

The ECQ-U2A104MV capacitor works by passing an electric current between its two internal terminals. The electric field between the plates causes the film dielectric between them to become polarized. This polarization creates the capacitance of the ECQ-U2A104MV, which is the capacity of the device to store electric energy. The dielectric absorbs energy from the electric field and stores it as potential energy. When the electric field is reversed, the energy stored in the dielectric is discharged to the electric field, thus completing the cycle.

In summary, the ECQ-U2A104MV is an ideal choice for applications in the AC-operating voltage range, such as power supplies and HVAC systems. It is well-suited to capacity-controlled motors, where its high working voltage and strong insulation offer efficient operation and reliability. As a film capacitor, it also offers greater operating stability than electrolytic capacitors and is much less prone to failure.
