Conductive Polymer Hybrid Aluminum Electrolytic Capacitors
Application
Guidelines
(Hybrid)
1. Circuit design
1.1 Operating temperature and frequency
Electrical characteristics of the capacitor are likely to change due to variation in temperature and/or frequency.
Circuit designers should take these changes into consideration.
(1) Effects of operating temperature on electrical parameters
At higher temperatures
: Leakage current increases
: Hybrid type has smaller capacitance and larger tan δ.
At lower temperatures
Other aluminum electrolytic capacitors have smaller capacitance, larger tan δ,
and larger impedance as well as equivalent series resistance (ESR).
(2) Effects of frequency on electrical parameters
At higher frequency capacitance and impedance decrease while tanδ increases.
At lower frequency, heat generated by ripple current will rise due to an increase in equivalent series
resistance (ESR).
(1) Expected life is affected by operating temperature. Generally, each 10 °C reduction in temperature will double the
expected life. Use capacitors at the lowest possible temperature below the upper category temperature.
(2) If operating temperatures exceed the upper category limit, rapid deterioration of electrical parameter
will occur and irreversible damage will result.
Measure not only the ambient temperature but also the surface temperature of the capacitor’s case top,
which has effects of ripple current and radiated heat from power transistors, IC's, and/or resistors.
Avoid placing components, which could conduct heat to the capacitor from the back side of the circuit board.
(3) The formula for calculating expected life is as follows ;

: Upper category temperature (℃) *Hybrid type : + temperature rise due to rated ripple current (℃)
: Capacitor's ambient temperature (℃)
⊿T
: Temperature rise due to ripple current (°C)
(4) Using the capacitor beyond the rated lifetime will result in short circuit, electrolyte leak, vent open, and large
deterioration
of characteristics. The lifetime cannot exceed 15 years due to aging of sealing rubber.
(5) If the capacitor is used in a high temperature condition for a long time, micro cracks may appear on the surface
of sealing rubber, and/or capacitor case exterior may become brownish in color, but the product reliability will not
be influenced.
1.3 Load conditions to avoid
The following load conditions will cause rapid deterioration of capacitor’s electrical characteristics.
In addition, instantaneous heating and gas generation within the capacitor may cause an operation of pressure
relief vent, and that results in electrolyte leaks, explosion and/or fire ignition.
The leaked electrolyte is combustible and electrically conductive.
(1) Reverse voltage
DC capacitors have polarity. Therefore, do not apply the reverse voltage. Find the correct polarity before insertion.
(2) Charge / Discharge applications
General purpose capacitors are not suitable for use in repeating charge/discharge applications. For such applications,
consult a sales representative with actual application condition. Rush current must not exceed 100 A.
(3) ON-OFF circuit
When using capacitors in circuit where ON-OFF switching is repeated more than 10,000 times a day, consult a sales
representative with actual application condition for an appropriate choice of capacitors.
(4) Over voltage
Do not apply a voltage exceeding the rated voltage. The rated surge voltage can be applied only for a short time.
Make sure that a sum of the DC voltage and the superimposed AC ripple voltage does not exceed the rated voltage.
(5) Ripple current
Do not apply ripple currents exceeding the rated value.
Make sure that rated ripple currents superimposed on low DC bias voltages do not cause reverse voltage conditions.
Even if the current is below the rated ripple current, using the capacitor for longer than the rated lifetime will cause
ESR increase and internal generation of heat, which may eventually lead to vent open, bulging of case/rubber,
electrolyte leak, short circuit, explosion, or ignition in the worst case.
