1 Skywell s UNI-CON is aluminum solid electrolytic capacitor that uses organic semiconductors as electrolytes. Organic semiconductor has a high conductivity and high-temperature stability, therefore UNI-CON have an excellent performance and high reliability. The constructions of UNI-CON are roughly the same as an aluminum electrolytic capacitor.

8 Temperature Coefficient Ratio 2. Equivalent Series Resistance (ESR) At the frequency from 100KHz to 300KHz, the ESR should stay the same, for detail ESR specification, please refer to Characteristics Table. OPERATION PRECAUTIONS 1. Polarity Confirm the polarity, do not reverse the polarity when using. 2. Prohibits Circuits 1) High impedance voltage retention circuits 2) Coupling circuits 3) Time constant circuits 4) Circuits greatly affected by leakage current 3. Over Voltage Prohibited During Design 4. Sudden Charge & Discharge Restricted (for maintenance of high proof reliability) 5. Considerations When Soldering 1) Do not solder the UNI-CON by submerging it in melted solder. 2) Soldering condition: less than 10 seconds at 260 3) The leakage current value after soldering may increase a little depending on the soldering conditions. But the leakage current can be reduced through self-repaired by applying voltage. 8

9 APPLICATION NOTES 1. Operating Temperature Use the UNI-CON according to the specified operating temperature range. 2. Ripple Current Never make current larger than the permissible ripple current. 3. Leakage Current Leakage current increases slightly during high temperature no-load, damp heat load and rapid change of temperature with no voltage applied. However, leakage current will decrease by applying voltage at the maximum operating temperature in case it happened. 4. Applied Voltage For 2.0V to 20V products and 30WV products, 100% of the rated voltage can be applied without causing any problem. Use less than 80% of the following temperature reduction voltage for 25WV products. The reliability of UNI-CON, it is recommended that voltage applied to them should be less than 80% of the rated voltage. If the 25V rating are used at the temperature higher than 85, apply the temperature reducing voltage described as: 85 25V, V, V for the 2.0V to 20V rating, the reverse voltage should be less than 20% of the rating voltage for an extremely short period less than 10% for a certain continuous period. 5. Failure Mode UNI-CON may end worn-out in association with temperature. They may be defected accidentally by overvoltage or over-current mainly causing short circuit. The failure rate is dependent on the applied voltage and the ambient temperature. Contact Skywell s branch office nearest you or to the following if you have any question.
