Aluminum electrolytic capacitors  may cause explosion,fire,or other serious hazard if used outside the specified operating conditions. Please familiarize yourself with the instructions below before using these capacitors.ItemInstructionsOperating temperature, ripple current1.Check the operating and installation environment  and use     the capacitor within the range of the rated performance specified in    the catalog or specifications．2.Maintain operating temperature and ripple current within the specified    ranges. Base your choice of capacitors on the maximum load conditions.A    capacitor will overheat under excessive current,potentially resulting in    short circuit, fire, or other major failure.3.A    capacitor also generates the self heating.Please bear in mind that the    capacitor heats up the interior of the equipment,and take appropriate    precautions.Operate the unit under normal conditions and check the temperature    of the area surrounding the capacitor.4.The    permissible ripple current declines with the rise in ambient temperature (the    temperature of the capacitor's surroundings). Consider the permissible ripple    current at the maximum predictable ambient temperature.5.Electric characteristics change as frequencies change. Check frequency    changes in order to choose the right capacitor. Special attention needs to be    given to the self heating and short life time both low and high    frequency,when equivalent series resistance and inductance change.Applied voltage and other operating conditions1.In    general,capacitors have polarity.Applying reverse voltage or AC voltage to a    capacitor may activate the vent or cause a short circuit, fire or other major    failure. Use a special AC capacitor for AC voltage.2.Use    a bipolar capacitor for circuits whose polarity reverses. However, as in any    other case, do not use a bipolar capacitor in an AC circuit．3.Do    not apply voltage in excess of the rated voltage. When an AC voltage is    superimposed on DC voltage. prevent the peak value from exceeding the rated    voltage. Excessive voltage may cause a short circuit, fire, or other major    failure．4.Specifications    on surge voltage have restricted conditions and therefore do not guarantee    long hours of operation.Voltage should never exceed the rated voltage of the    capacitor. even for brief periods. Choose your capacitor accordingly.5.When    connecting more than one capacitor in parallel,give proper consideration to    the resistance of the wiring.Establish the connections so that the wiring    resistance will be equal at every capacitor.6.When    connecting more than one capacitor in series, all must be of identical    rating, then the balancing     resistors  connected  in parallel. At that time, design the    circuit so that equal voltage levels are applied to all the capacitors.    Ascertain that the voltage applied to each individual capacitor does not    exceed its rated voltage.7.Take    into account the service life of the equipment in the use of the capacitor.    Use of the capacitor beyond its service life risks such failures as safety    vent activation or short circuit. Replace as necessary at regular inspection.8.Do    not use a capacitor for a circuit that is quickly charged and discharged repeatedly.    Use a dedicated capacitor for an application like a welding unit or photo    flash charging/discharging.  Consult us    for selecting  the proper capacitor,  since the control circuits of certain    rotation equipment, like servo motors, charge and discharge repeatedly.9.Even    slow charging/discharging can shorten the service life of a capacitor,    resulting in premature failure, where there are marked changes in voltage    changes. Check the installation in your equipment carefully and consult us.10.　General    purpose capacitors should not be used for a circuit involving rapid charge    and discharge or an A.C. circuit. Capacitors specially made for such    applications should be used.      →Check    the self heating of the capacitor used in such a circuit in addition to the    types and levels to be imposed to the capacitor of the rapid    charge/discharge, rush current and voltage.Before installation1.Check    the specifications of the capacitors, and install them within the prescribed    specifications.2.Do    not reverse the polarity. Do not use a capacitor where reverse voltage is    applied, even if it appears problem-free. Not taking these precautions could    lead to a major failure.3.Dropping    or otherwise impacting a capacitor may result in a decline in its electric    performance, causing a failure. Do not use any capacitor whose packaging has    a noticeable abnormality on delivery.4.Do    not distort the shape of the capacitor, which may lead the major failures    such as liquid leakage or short circuit.5.Do    not reuse a capacitor that has previously been installed on a machine and    energized. No capacitor can be reused ( with the exception      of    removal for measuring electrical performance during periodic checkups).Shenmao:The Foremost Leading manufacturer of Aluminum Electrolytic Capacitor over 49 years！Shenmao:The Foremost Leading manufacturer of Aluminum Electrolytic Capacitor over 49 years！

Service Life of an Aluminum Electrolytic Capacitor【Factors affecting service life】Environmental factors affecting the service life of an aluminum electrolytic capacitor include temperature.humidity and vibration (environment),as well as electrical factors,applied voltage,ripple current and charging/discharging conditions.In capacitors for mid-to-high-voltage filters, temperature and applied voltage are the most important controlling factors.The estimated service life  may be calculated based on the core temperature of the capacitor and the applied voltage.【Temperature conditions】Capacitance change or tangent change for loss angle indicates that the product life has been effected by temperature. Generally, as the ambient temperature(ambient temperature of the capacitor)increases,capacitance decreases and tangent change for loss angle takes place more rapidly.This is mainly because electrolytic solution generates gas due to electrode reaction and diffuses it outside via a sealing rubber.The following expression(1) indicates the relation between the ambient temperature and electric characteristic that changes with time(while the capacitor is used normally according to the rules of serviceability).Where:L  : Estimated service life in actual use.Lo : Standard service life when allowable ripple current load or rated voltage is applied at the maximum operating temperature.To : Maximum core temperature setting when subjected to the maximum allowable ripple load at the maximum operating temperature (settings differ in different series or products. Contact us for details).T  : Core temperature of the capacitor during actual use.Therefore,the lower the core temperature of the capacitor during actual use, the longer the estimated service life is.The core temperature of a capacitor may be lowered by lowering either the ambient temperature or the load current (operating conditions),or by either boosting capacitance or lowering internal resistance. Some capacitors feature a radiating structure to lower the core temperature. Consult us for the selection of capacitors. When multiple capacitors are connected in parallel,check the core temperature in each capacitors and the balance of the tatal series resistance to each capacitors. If capacitors are used at high frequency, the circuit resistance is especially need to considered. The estimating service life is needed to calculated from the maximum core temperature.Shenmao:The Foremost Leading manufacturer of Aluminum Electrolytic Capacitor over 49 years!
