Film capacitors, also known as plastic or non-electrolytic capacitors, are a type of capacitor that uses a film as a dielectric material for its construction. They are often used in applications where the capacitance needs to be changed or adjusted, as well as in audio applications where their small size and low cost make them an attractive option. The ECQ-E2154KF3 is one such film capacitor, designed to meet the demands of high frequency applications.

The ECQ-E2154KF3 is a metallized polyester film capacitor manufactured by Panasonic, with a capacitance of 0.00154μF and a tolerance of ± 5%. The capacitor is rated at 25 VDC operating voltage and a maximum sustained voltage of 75 VDC. The upper extreme in temperature range is 125°C and the lower extreme is -65°C. The physical dimensions of the device are 5mm in diameter and 7mm in height.

The working principle of the ECQ-E2154KF3 film capacitor is quite simple. When a voltage is applied across its electrical terminals, the capacitance value is determined by the ability of the dielectric material (in this case, a film) to store electrical charge. This capacitor is constructed from a plastic film sandwiched between layers of metal electrodes and has a non-polar structure, meaning that it does not have a positive or negative terminal and can be equally charged or discharged from either end. This type of capacitor is also known for its low equivalent series resistance, which allows it to maintain a stable performance across a wide frequency range.

There are a variety of applications that the ECQ-E2154KF3 film capacitor can be used in and it is often seen in power conditioners, power bases and DC power supplies. It can be used to decouple noise from audio applications, such as radios and amplifiers, and is also used in switch mode power supply circuits. The capacitor helps to reduce the electromagnetic interference of systems, as it can filter out high frequency noise before it is transmitted.

In general, the ECQ-E2154KF3 film capacitor is an excellent choice for applications that are dealing with a wide range of frequencies. The capacitor is small in size and low in cost, making it an attractive option for many applications. It is also capable of handling higher voltages, temperatures, and can store electrical charge for many years with minimal degradation.
