Characteristics of thin film capacitors

Non-polarity: When used in the circuit, there is no need to strictly distinguish between positive and negative electrodes like polar capacitors such as electrolytic capacitors, and the use is more flexible and convenient, and can adapt to a variety of different circuit topologies and working conditions.

High insulation impedance: can effectively reduce the leakage current, ensure that the capacitor in the storage and release of charge in the process of energy loss is small, improve the stability and efficiency of the circuit, reduce the risk of circuit failure caused by leakage.

Excellent frequency characteristics: has a wide frequency response range, can maintain good performance in high frequency and low frequency circuits, can be used to process signals of various frequencies, such as in the communication circuit can well process high frequency signals, in the audio circuit can also effectively process low frequency signals.

Small dielectric loss: under the action of the electric field, less energy is consumed due to heating and other reasons, which means that the capacitor can work more efficiently, reduce energy waste, and improve the energy efficiency ratio of the entire circuit, especially in high frequency and high power circuits, this characteristic is more important.

Possible fields of application

For example, in solar inverters, thin film capacitors can be used for filtering and energy storage when converting direct current output from solar panels to alternating current.

Industrial automation: In the motor drive system, the control circuit of the automatic production line, etc., it plays the role of stabilizing voltage and eliminating interference, ensuring the accurate control and reliable operation of industrial equipment. For example, in the control system of CNC machine tools, thin film capacitors can ensure the stability of the motor drive signal and improve the processing accuracy.

Consumer electronics: commonly used in audio equipment, televisions, computers and other products, for audio filtering, power decoupling, etc., to improve the quality of audio and video signals, reduce noise and interference. Taking audio equipment as an example, thin film capacitors can be used to filter circuits to make audio signals more pure and improve sound quality.

New energy vehicles: In the battery management system of electric vehicles, on-board chargers, drive motor controllers and other components, it undertakes important tasks such as energy storage, voltage conversion and filtering, which is crucial to improve the performance and reliability of new energy vehicles. For example, in battery management systems, thin film capacitors can be used to stabilize the output voltage of the battery pack and protect the battery and other circuit components
