What should be paid attention to when using metalized capacitors
①. Moisture, dust reactivity, acidified gas (salted hydrogen, acidified hydrogen, sulfite gas) will have a degrading effect on the welding terminals of the external electrode of the metalized capacitor, and the above problems must be paid attention to.
②. Especially avoid places with high temperature and humidity, store at -10~40℃, humidity below 85%, and do not directly expose to water or moisture, so as to avoid moisture intrusion and damage the metalized capacitor.
Problems that should be paid attention to when using
①.Metalized capacitors must avoid environments with rapid voltage changes or rapid temperature changes, even if the rated value of the metalized capacitor is not exceeded, it will cause rapid deterioration of the quality of the metalized capacitor.
②. If metallized capacitors are used in circuits, there are rapid or frequent charging and discharging, special frequencies such as high frequencies or different atmospheric pressures. The applicability of metallized capacitors must be confirmed.
③.Metalized capacitor voltage test, life test, when multiple metalized capacitors must be connected in parallel, metalized capacitors must be connected in series with resistance.
④. When general metalized capacitors are subjected to over-voltage, abnormal over-temperature or the end of the product life, and the insulation is damaged, the metalized capacitors may smoke or burn out. In order to prevent this from happening, protection must be used. The type of metalized capacitor makes the metalized capacitor break with the circuit when an abnormal situation occurs, so as to achieve the protection effect.
