1. Electrolytic capacitors in the filter circuit in accordance with the specific Capacitor AC Metallized Polypropylene conditions for noise voltage value from the peak of 1.2 - 1.5 times the filter circuit is not in accordance with the ratings;

     2. Electrolytic capacitor is not a pad below and through-hole.

     3. Electrolytic capacitors and neighboring not direct contact with the heating elements.

     Electrolytic capacitors applicable guidelines "are as follows:

     4. Aluminum electrolytic capacitor is the anode, and not reverse voltage and AC voltage, reverse voltage of the possible areas of the capacitor should be used Promise.

     5. Need rapid charge and discharge areas, should not be Capacitor AC Metallized Polypropylene used electrolytic capacitors, should choose specially designed with a longer life expectancy capacitors.

     6. Should not use overload voltage

     A. DC voltage-cultural stack voltage lower than the rated voltage sewing.

     B. electrolytic capacitor in series of two or more time to consider the balance between the use of resistors, capacitors made all the rated voltage range.

     7. Design circuit boards, capacitors should pay attention to top-explosion-proof valve shall not have any lines, and should stay out of the more than 2 mm gap.

     8. Electrolytic chemical solvents and also the main paper for electrolytic Capacitor AC Metallized Polypropylene combustibles, and the electrolyte conductivity. Pc board when contact with the electrolyte, which may corrosion pc board line. That smoke or fire. Therefore not in the electrolytic capacitors Below have any lines.

     9. PCB design fever components should be recognized not near aluminum electrolytic capacitor or electrolytic capacitors below.
