Film capacitors, also known as plastic capacitors, are non-polarized, polarized, and/or superfine capacitors constructed using a thin film of dielectric material, typically made of polyethylene terephthalate, or polypropylene. These capacitors can be used for applications such as power supply filtering, timing, frequency selection, coupling, and decoupling. They offer high dielectric strength, excellent stability, and accurate capacitance values.

The F1778368M2F0W0 film capacitor is a non-polarized capacitor with a rated working voltage of 250VAC. It has a capacitance value of 1.0µF, a temperature coefficient of ±15%, and a tolerance of ±5%. It is constructed using polyester film as the dielectric. This capacitor has a maximum reverse voltage of 500V, a dielectric loss tangent of 0.18% at 1KHz, and a self-heating of 4 mW/°C. The capacitor has a radial lead diameter of 1mm, a lead pitch of 5mm, and a radial lead length of 10±2 mm.

The F1778368M2F0W0 film capacitor has a wide range of applications, including AC power supply filtering, audio noise interference suppression, timing and frequency selection in communications and automotive electronics, and coupling and decoupling in microprocessors. The capacitor can also be used in motor drive circuits and high-frequency switching.

The working principle of a film capacitor is based on the principle of electrostatics. When the capacitor’s terminals are connected to an AC power source, a continuous electric field is created between the two metallic electrodes. The electric field creates an electrical potential difference that causes electrons and ions to be attracted to the opposite poles of the electrodes. This creates a charge separation, which results in a capacitance between the two electrodes. As current passes through the capacitor, the electrons are stored and released in the form of AC current.

The F1778368M2F0W0 film capacitor is a reliable and effective device for applications that require precise capacitance values, stable performance, and high dielectric strength. It is an excellent choice for applications in audio noise suppression, timing and frequency selection, motor drive circuits, and other areas where a non-polarized capacitor is needed.
