Film capacitors, better known as film dielectric capacitors, are engineered electronic devices typically composed of an insulating material sandwiched between two conductive surfaces. The insulating material is usually an enameled or plasticized film such as polycarbonate, polyester, polyimide or polypropylene. Varieties of film capacitors exist and they can range in size from a few pico-farads to thousands of micro-farads.

The ECQ-E2103KB3 is a Film Capacitor specifically designed for the audio frequency filter market. It is a non-inductive type of capacitor, which means it does not produce inductive losses. This is due to its Design Evolved from Metallized Polyester Film (MELF-type) capacitors. It has an operating temperature range of -25°C to +125°C, making it suitable for many environments. It also has excellent electrical properties such as high insulation resistance, low equivalent series resistance (ESR), and high ripple current capability.

The ECQ-E2103KB3 application field covers a variety of functions, including frequency filtering, AC line filtering, blocking DC voltage, signal coupling, pulse shaping, mains frequency smoothing, and signal bypassing. It is highly reliable and manufactured with materials that follow UL 94 V-0 standards, making it a great choice for high-end applications.

In terms of its working principle, the ECQ-E2103KB3 capacitor works by storing electrical energy in the form of an electrostatic field. This field is created when two electrodes are separated by an insulating dielectric material, forming an electrical capacitance. The capacitor is then charged by allowing an electric current to flow between the electrodes, resulting in accumulated electrical energy.

When the capacitor is discharged, the accumulated electrical energy stored in the capacitor’s electrostatic field is released as an electric current. This electric current is then used for any number of applications, from audio frequency filtering to DC voltage blocking.

Overall, the ECQ-E2103KB3 Film Capacitor is an excellent choice for applications that require high-frequency filtering, shock resistance, and long-term stability. It is also an eco-friendly option due to its low power consumption, making it a viable choice for applications that require an environmentally friendly electronic component.
