塑胶薄膜电容器 学术笔记

1. Principle and Basic Theory of Capacitor
2. Kinds of Capacitors
3. Kinds of Film Capacitors
4. Characteristics and Performance

What is the Capacitor?
When voltage is applied between facing conductors, the insulator (or space) sandwiched between them will cause dielectric polarization by electrostatic induction, thus leading to the accumulation of electric charges (charging). The capacitor is a device (part) that performs this charging and discharging of accumulated charges as its function.

5. Key Points of Reliability and Quality in Manufacturing

5.1 Control items and influencing characteristics by kinds of products and processes

6. Applications

6.1 Outlined applications by kinds of dielectrics and electrodes
6.2 Concrete examples of applications

7. Precautions on Use

(1) Rated voltage
(2) Allowable current depending on the frequency
(3) Self temperature rise
(4) Operating temperature range
(5) In case of use for anti-noise purpose
(6) In case of use for charging/discharging circuit
(7) Beat noise
(8) In case of use for the circuit requiring severe conditions for time constant, etc.
(9) Soldering operation
(10) Comments on washing(solvent)
(11) Storing conditions
(12) In case of scrapping

8. Examples of Failures

- Probable causes of failure and failure mode of film capacitors
- Concrete example

9. Safety and Environmental Protection

- Safety
- Environmental Protection

10. Future Prospects

- Miniaturization by manufacturing method for unification of dielectric film formation and evaporation
- Development of higher allowable current products to enhance the superiority of low loss.
- Reduction of noise generated when AC voltage is applied
