Film Capacitors

Film capacitors are capacitors whose dielectric is a thin plastic film. These capacitors can have operating temperatures of up to 200 degrees Celsius, while some are designed for even higher temperatures. Additionally, these capacitors usually have excellent frequency characteristics and an ultra-low DF value. They generally have a small volume, long life, and are highly reliable.

The MMP1W10K-F is a metallized film capacitor designed for high temperature and high frequency applications. This device is constructed using a flexible polyethylene-naphthalate (PEN) film and a metalized finish. Its features include low ESR values, high frequency performance, wide operating temperature range, high capacitance stability with temperature, and low DF values. The MMP1W10K-F is ideal for use in switch mode power supplies, high frequency power converters, invertors, and SMPS. It is also commonly used in automotive, industrial and communication systems.

The working principle of a film capacitor is based on the fact that two electrodes, each with an electrical charge, produce and electric field. The electric field draws the electric current through the media and accumulates it between the electrodes. This in turn produces a counter-force, creating an electrical potential difference across the terminals of the capacitor. The stored charge is then discharged when an electric device draws current through it.

The MMP1W10K-F is a DC type film capacitor, which means that it can only store an electric charge that is proportional to the applied voltage. The stored charge can be released rapidly during a load switch triggering a large discharge current, but it is unable to maintain a varying current. This type of capacitor can operate at relatively high temperatures, including up to 200 degrees Celsius, while having a wide operating frequency range.

In order to ensure best performance and reliability the MMP1W10K-F capacitor must be operated within its specified temperature and frequency range. Over and under temperature exposures can cause damage to the capacitor and reduce its performance, while over frequency can cause frequency dependent self-heating, which can further accelerate the degradation of the device.

Overall, the MMP1W10K-F capacitor is an ideal solution for high temperature and high frequency applications. With its low ESR value, wide operating temperature range, and high capacitance stability, it is well suited for automotive, industrial and communication systems. Additionally, this device has a long lifetime and is highly reliable ensuring low risk of mechanical breakdown or component failure.
