Regular electrolytic capacitors has polarity.
Reverse voltage causes short circuit breakage of the capacitor or leakage of electrolyte.Where the polarity in a circuit sometimes reversed or unknown,a bi-polar capacitor should be used.
When you use aluminum electrolytic capacitors,remember the following.
Regular electrolytic capacitors has polarity.
Reverse voltage causes short circuit breakage of the capacitor or leakage of electrolyte.Where the polarity in a circuit sometimes reversed or unknown,a bi-polar capacitor should be used.
Do not apply overvoltage continuously.
When overvoltage is applied to the capacitor,leakage current increase drastically.
Applied working voltage to capacitors should not exceed the rated working voltage of capacitor.
Do not use the capacitor over the max operating temperature.
Life time of the capacitor depends on the temperature.
Generally,life time is doubled by decreasing each temperature 10 degree.
Use temperature as low as possible.
It is recommended at least 3mm of space around the vent.
If such space is not provided,the vent will not operate completely.
Do not apply a ripple current exceeding the rated maximum ripple current.
Applying too much ripple current to the capacitor causes great heat generation,invites deterioration of properties of case breakage.
Please consult factory if ripple current exceeds the specified limit.
Frequent and quick charge/discharge generates heat inside the capacitor,cause increase of leakage current,decrease of capacitance,or breakage occasionally.
Consult us for assistance in this application.
When the capacitor is stored for a long time without applying voltage,leakage current tends to increase.
This returns to normal by applying the rated voltage to the capacitor before use.
It is recommended to apply D.C. Working voltage to the capacitor for 30 minutes through 1K Ω of protective series resistor,if it is stored for more than 6 months.
The capacitor should be stored at temperature 5 degree.to 35 degree,with humidity of 75% or less.
Improper soldering may shrink or break the insulating sleeve and/or damage the internal element as terminals and lead wires conduct heat into the capacitor.
Avoid too high a soldering temperature and/or too long a soldering time.
Do not apply excessive force to the lead wire and the terminal.
Do not move the capacitor after soldering to the PC board,not carry the PC hoard picking up the capacitor.For their strength,refer to JIS C-5141 and C-5102.
If the capacitor is cleaned in halogenated solvent for organic removing solder flux solvent,the solvent may penetrate into the inside of capacitor,and may generate corrosion.
The standard sleeve material is polyethylene terephthalate.
If exposed to xylene,toluene,etc,and then subjected to high heat,the sleeve may crack.This sleeve is not insulating material.
