Film capacitors, also called polyester capacitors and plastic film capacitors, can be made using polystyrene, polycarbonate, polypropylene, polyethylene naphthalate or polyvinylidene fluoride materials. These types of capacitor design offer a wide range of characteristics such as excellent high frequency response, high dielectric constants, low losses, low leakages and low temperature coefficients.

The ECH-U1C683JB5 film capacitor is a non-polarised capacitor, meaning it does not have a positive and a negative terminal. It has a maximum working temperature of 105°C and a capacitance range of 0.001 – 0.1 μF, at a voltage range of 50V to 1KV. The ECH-U1C683JB5 is mainly used in high frequency AC to DC rectification, high frequency signal attenuation, electromagnetic radiation suppression and can also be used for some AC filters.

The working principle of the ECH-U1C683JB5 film capacitor is based on the electrostatic principle, wherein a capacitor has two charged plates separated by a dielectric, or insulating material, such as plastic film. When a voltage is applied across the plates, the dielectric material accumulates a charge and produces a dielectric field between the plates. This stored energy, or charge, builds up until it is either removed or the maximum voltage of the capacitor is reached. The capacitor can then be discharged by shorting the two electrodes, which causes a sudden surge of current and drops the voltage across the plates to zero, resulting in the capacitor\'s charge being discharged.

The ECH-U1C683JB5 film capacitor is largely used in power supplies, as in switching power supplies, electrolytic capacitors tend to introduce high losses resulting in high power consumption and heat generation. Film capacitors are also replaced electrolytic capacitors in high-frequency or high voltage circuits, as the ECH-U1C683JB5 film capacitor has a lower ESR rating than electrolytic capacitors due its low leakage current, high breakdown voltage and dielectric constant.

In addition to power supplies, the ECH-U1C683JB5 is also used in filter circuits. As a filter capacitor, it reduces the extremes of the AC signal and provides a much smoother DC output. It is often used in audio applications, such as in guitar pedals, to reduce AC ripple and contamination of the signal chain. The ECH-U1C683JB5 film capacitor can also be used in motor speed control and timer applications, as well as motor start circuits.

The ECH-U1C683JB5 is a great option for many different applications, owing to its high reliability, high dielectric constants, long life and low temperature coefficients. This makes the ECH-U1C683JB5 ideal for use in high frequency AC to DC rectification, high frequency signal attenuation, electromagnetic radiation suppression, AC filters, power supplies, filter circuits, audio applications, motor speed control and motor start circuits.
