Film capacitors are commonplace in many electronic circuits. The 265HC4700K2EM8 is a film capacitor from Semtron Electronics. It is a two-terminal, solid-state device that consists of two electrodes separated by a thin layer of plastic film or foil. It is used to store electrical energy and filter out unwanted frequencies from a signal.

Film capacitors are often used for applications that require precise electrical characteristics, such as power supply filtering, noise suppression, and audio crossover networks. The 265HC4700K2EM8 is no exception. This product\'s extremely low DC resistor, very low leakage and long life expectancy make it an ideal choice for these applications.

The capacitance of a film capacitor is measured in farads. The 265HC4700K2EM8 has a capacitance of 4700 pF (pico-farads). This is enough to provide efficient filtering or, when combined with resistors, to provide damping for oscillations. Its voltage rating is 250VAC, which means it is suitable for AC line-operated lighting and many other applications.

The 265HC4700K2EM8 has a high dielectric strength. This is important for circuits where a high voltage may be present, such as power supplies. It also has excellent heat resistance, which makes it suitable for use in high temperature environments.

The construction of a film capacitor involves winding multiple layers of foil separated by thin layers of film into a roll. The roll is then rolled up and encapsulated in a plastic casing. This construction makes film capacitors smaller than other types of capacitors, which is why they are often used in portable electronics. As they are very tolerant of temperature variations, they are also popular in automotive and aerospace applications.

The main working principle of a film capacitor is capacitive storage. The capacitor stores electric charge in its dielectric material (a plastic film or foil) between its two electrodes. When the input voltage is applied to the capacitor, electrical charge transfers from one electrode to the other and the capacitor is said to be "charged". This stored energy is then released as the input voltage decreases, thus improving the stability of a power supply and the phase shift of an AC waveform.

The 265HC4700K2EM8 is a reliable and versatile capacitor which is suitable for many applications. Its construction makes it small and versatile, while its high capacitance and excellent electrical characteristics make it an ideal choice for applications requiring precise levels of voltage, current, and frequency.
