Polyester polyester film capacitors play an important role in all kinds of electronic equipment, and their reliability and life expectancy directly affect the performance of the entire system. In order to ensure that the capacitors can work stably for a long time, reasonable care and maintenance are crucial. The following are some effective ways to extend the service life of polyester polyester film capacitors.

Care and Maintenance: Extending the Life of Polyester Polyester Film Capacitors

First, maintain a suitable working environment. The operating temperature range of capacitors is generally between -40°C and +105°C. Excessively high or low temperatures will affect their performance and life. Therefore, avoid placing capacitors in extreme temperature environments and ensure that the equipment has adequate heat dissipation measures. In addition, humidity can affect the performance of capacitors. Excessive humidity may cause oxidization of the internal metal parts of polyester film capacitors, thus reducing their reliability. It is recommended that the relative humidity of the working environment be controlled between 40% and 60%.

Next, pay attention to the stability of voltage and current. Capacitors operating under over-voltage or over-current conditions are prone to internal heating and aging, thus shortening their service life. Therefore, you should ensure that the power supply voltage and current are stable, and avoid frequent voltage fluctuations and surge impact. The use of regulated power supplies and surge protectors can effectively reduce the occurrence of these problems.

Regular inspection and maintenance are also important measures to extend the service life of polyester capacitors. During the operation of the equipment, the appearance of the capacitor should be checked regularly to find out whether there is any deformation, liquid leakage or abnormal heating phenomenon. At the same time, the capacitor's capacitance, loss factor and insulation resistance and other parameters can be tested by instruments to detect potential problems in time. Once the performance of the capacitor is found to be degraded, it should be replaced in time to avoid the expansion of the fault.

In addition, reasonable design and installation can also effectively extend the service life of capacitors. In circuit design, the heat dissipation needs of capacitors should be taken into account to avoid dense arrangement and proximity of heat sources. When installing, attention should be paid to the polarity of the capacitor to avoid reverse connection and misconnection. At the same time, minimize the mechanical stress on the capacitors to avoid damage caused by vibration and shock.

Finally, follow proper operating procedures. In the process of equipment startup and shutdown, it should be operated in accordance with the prescribed steps to avoid sudden power failure and frequent switching. Operators should be professionally trained to master basic capacitor knowledge and operating skills to avoid damage to capacitors due to misoperation.

In conclusion, by maintaining a suitable working environment, paying attention to the stability of voltage and current, regular inspection and maintenance, reasonable design and installation, as well as following the correct operating procedures, the service life of polyester polyester film capacitors can be effectively prolonged to ensure the long-term stable operation of the equipment.
