ECQ-E4273KZ

Film capacitors are a type of capacitor that has a thin film of plastic as the dielectric material. This thin film is usually made of polypropylene, polyester, or polystyrene. Film capacitors can be manufactured with either a zero-bias voltage rating or a bias voltage rating. The zero-bias version is designed to withstand no bias voltage while the bias version can handle some amount of bias voltage applied. Film capacitors have a high temperature coefficient, which makes them well suited for use in high voltage and high temperature applications such as motor drives, UPS, and AC inverters.

The ECQ-E4273KZ is a film capacitor that has a zero-bias voltage rating of 400V and a capacitance range of 2.2-10μF. It has an operating temperature range of -25°C to +105°C, and is made with a polyester film. The ECQ-E4273KZ is designed to have excellent stability and reliability. It is shock resistant, stable in terms of capacitance and ESR, and is able to tolerate high humidity environments.

The ECQ-E4273KZ is primarily used in motor drives, UPS systems, AC inverters, high-frequency transformers, DC/DC converters, solid-state relays, and ballasts. It is well suited for these applications as it is able to withstand temperature extremes and extreme voltage transients. It is also resistant to moisture and has excellent stability in terms of capacitance and ESR. The ECQ-E4273KZ is able to operate at high frequencies and is compatioble with lead-free soldering.

The working principle of the ECQ-E4273KZ is similar to other types of capacitors. It works by storing energy in its electric field and releasing it as an electric current when an electric field is applied. This action is due to the capacitive property of the polyethylene film, which allows it to store electrical charge when an electric field is applied. By varying the applied voltage, the amount of charge stored can be controlled. When the voltage is removed, the charge stored is released as an electric current. This allows the ECQ-E4273KZ to act as a voltage regulator in applications where a constant voltage is required.
