With no bias characteristics and stable temperature characteristics, ECAS series have excellent performance in ripple absorption, smoothing and transient response suitable for numerous applications. Therefore, it is suitable for smoothing of input-output current of various power supply circuits, and the backup use over the load change of the CPU circumference. This contributes to reduction of the number of parts, or reduction of substrate area. **==> picture [480 x 213] intentionally omitted <==** **----- Start of picture text -----**

Therefore, please approve our product specifi cations or transact the approval sheet for product specifi cations before ordering. ## **Cautions for Use** c Cautions ## <1>Prohibited Circuits ECAS series cannot be used on the following circuits. 1. Time constant circuits, 2. Coupling circuits, 3. The circuits in which two or more ECAS series are connected in a series so as to raise the endurance voltage, 4. Circuits greatly affected by leakage current. <2>Polarity Polymer aluminum electrolytic capacitor is polarized. Please not to reverse the polarity when using. If reverse voltage is applied, it may damage the oxide film and the capacitor itself. <3>Operating Voltage When DC-rated capacitors are to be used in AC or ripple current circuits, be sure to maintain the Vp-p value of the applied voltage or the Vo-p which contains DC bias within the rated voltage range. When the voltage is applied to the circuit, starting or stopping may generate irregular voltage for a transit period because of resonance or switching. Be sure to use a capacitor with a rated voltage range that includes these irregular voltages. - <4>Inrush Current Extreme inrush current may cause short circuit or leakage current increase. If the inrush current exceeds 20A, adding protection circuit is recommended. ## <5>Allowable Ripple Current Please not to apply ripple current exceeding the allowable value specified in this document. If excessive current is applied, it may generate heat and the heat may damage the capacitor. The sum of DC voltage and the peak AC voltage shall not exceed the rated voltage. The sum of the DC voltage and the peak AC voltage shall not allow a voltage reversal. Maximum allowable ripple current = Allowable Ripple Current x *Temperature Compensation Coefficient *Temperature Compensation Coefficient = 1.00(TB45°C), 0.70(45°COperating Temperature The operating temperature limit depends on the capacitor. qDo not apply temperature exceeding the upper operating temperature. It is necessary to select a capacitor with a suitable rated temperature that will cover the operating temperature range. Also it is necessary to consider the temperature distribution in equipment and the seasonal temperature variable factor. wConsider the self-heating of the capacitor. The surface temperature of the capacitor shall be the upper operating temperature or less when including the self-heating factors. ## <7>Reflow Soldering Please not to apply excessive force to the capacitor during insertion as well as after soldering. The excessive force may result in damage to electrode terminals and/or degradation of electrical performance. ## <8>Operating Environment Confirm the environment in which the equipment will operate is under the specified conditions. Do not use the equipment under the following environments. qBeing spattered with water or oil. wBeing exposed to direct sunlight. eBeing exposed to Ozone, ultraviolet rays or radiation. rBeing exposed to toxic gas (e.g., hydrogen sulfide, sulfur dioxide, chlorine, ammonia gas, etc.) tBeing exposed to excessive vibrations or mechanical shocks. yBeing exposed to condensable environments. <9>Failure Rate The failure rate is 0.5%/1,000h (60% Reliability) based on JIS C 5003. c Storage Conditions <1>Term of warranty for this product is two years after packaging in a moisture-proof bag, under the conditions below with sealed packaging. Recommended storage environment: Room temperature: 5-30°C Humidity : no more than 60%RH <2>Polymer aluminum electrolytic capacitors should not be stored in an atmosphere consisting of corrosive gas (e.g., hydrogen sulfide, sulfur dioxide, chlorine, ammonia gas, etc.). <3>Polymer aluminum electrolytic capacitors should be stored in a dry atmosphere, avoiding direct sunlight and condensation. If capacitors are kept at a higher humidity, the following problems may occur: qLeakage current will increase at the beginning of use and damage the circuit. wMoisture absorbed in a resin will evaporate and expand with heat of mounting and damage the mold resin. - <4>Please confirm a dry state with a humidity indicator card after open immediately. If 20% indication was in a pink state after opened, it is recommended to bake under the conditions below as countermeasures against the problems q and w in <3> above respectively. <5>The capacitors should be kept dry using desiccators or any other methods after unsealing the moisture-proof packaging. If more than two weeks has passed under the recommended storage environment specified above after unsealing the packaging, it is recommended to apply voltage and to bake under the conditions below, as countermeasures against the problems q and w in <3> above respectively. qRecommended voltage conditions: wRecommended baking conditions: Applied voltage : rated voltage Temperature: 60 (+0, -5) °C Time : 30 minutes Time : 168 hours Temperature : room temperature Current limiting resistance: 1000Ω (series connection) <6>This product meets MSL-3. 7 C90E.pdf May.17,2012 !Note[• Please read rating and ][!][CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.] • This catalog has only typical specifi cations.
