Characteristics and application of metallized film capacitors

Metallized film capacitors are one of the most widely used electronic components in electronic devices, and are widely used in circuit blocks and passing, coupling, bypassing, filtering, tuning loops, control and other respects.

Metallized film capacitors are suitable for high frequency circuits and can be classified into foil type and silver type according to the structure. The silver electrode is directly deposited on the metal diaphragm by vacuum evaporation or infiltration. The temperature coefficient is greatly reduced due to the elimination of the air gap, and the stability of the metallized film capacitors is higher than that of the foil. It is characterized by good frequency characteristics and high Q value.

The metallized film capacitors are formed by spraying a special mixture of a concentration suitable for spraying into a thin film, and the medium is sintered by a silver layer electrode to form a monolith structure. The utility model has the advantages of small volume, high sensitivity, low power consumption, good reliability, low cost and good frequency characteristics, so it is widely used for sounding applications of various electrical products. It is commonly used as a sounding device for small electronic products such as music greeting cards, electronic watches, pocket calculators, electronic doorbells and electronic toys.

Metallized film capacitors are now more and more widely used, and will inevitably become the capacitors needed for the development of various industries in the future. Therefore, it is important to understand its characteristics and applications. If there are technical problems with metallized film capacitors, we will try our best to solve them for you.
