Electrolytic capacitor 1000UF25V long life LOWESR 105° switching power supply inverter commonly used super capacitor This capacitor is rated at 1000uf and 25V. 1000uf 25v Capacitor indicates electrostatic capacity of 1000uF, while 25V indicates voltage of 25v. The 1000uf25V radial electrolytic capacitor has high reliability and long life, and is commonly used in power supply circuits as filter capacitor. When we buy capacitors, the higher the capacitance is, the better it is, it is enough to meet our use. SHDR® Application Notes 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: 1. Polarity Regular aluminum 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. 2. Overvoltage 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. 3. Operating temperature and life 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℃ Use temperature as low as possible. 4. Vent It is recommended at least 3mm of space around the vent. If such space is not provided, the vent will not operate completely. 5. Ripple current 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 causes breakage. Please consult factory if ripple current exceeds the specified limit. 6. Charge and discharging Frequent and quick charge/discharge generates heat inside the capacitor, causing increase of leakage current, decrease of capacitor, or breakage occasionally. Consult us for assistance in this application. 7. Storage 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 1kΩ of protective series resistor, if it is stored for more than 6 mouths. The capacitor should be stored at a normal temperature and humidity. 8. Soldering Improper soldering may shrink or break the insulating sleeve add/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. 9. Mechanical stress on the lead wire and the terminal 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 board by picking up the capacitor. For their strength, refer to JIS C-5141 and C-5102. 10. Cleaning of boards after soldering If the capacitor is cleaned in halogenated solvent for organic removing solder flux solvent, the solvent may penetrate into inside of capacitor, and may generate corrosion. 11. Sleeve material The standard sleeve material is polyvinyl-chloride. If exposed to xylene, toluene, etc, and then subjected to high heat, the sleeve may crack. This sleeve is not insulating material. 12. Micon's Products meet or exceed quality standards specified by JIS-C5141W and with the reliability requirements refer to JIS-C-5102.
