Guidelines and precautions (POSCAP)
1. Circuit design
1.1 Prohibited circuits
Since problems can be expected, POSCAP cannot be used on the following circuits
(1) High impedance voltage retention circuits
(2) Time constant circuits
(3) Circuits greatly affected by leakage current
(4) The circuit in which two or more POSCAP are connected in a series so as to raise the endurance voltage.
1.2 Failure and life-span
The failure rate is 0.5 %
½
/ 1000 h (Confidence level : 60 %) based on JIS C 5003.
The mainly failure modes are as follows.
½
B2 size or less : 1.0 %
1.2-1 Contingency failure
The main causes of failure are thermal stresses cause by the soldering or thermal use environment, along with
heat stresses, electrical stresses or mechanical stresses. The most common failure mode is a short circuit.
In case a short circuit occurs, ensure safety by fully considering the followings.
(1) If POSCAP emit smoke, turn off the main power of the equipment. In this case, keep your face and
hands away from the area.
(2) It may take a few seconds to a few minutes before POSCAP emits smoke by the situation. Increase
safety by using a protective circuit.
(3) If the smoke comes into eyes, rinse immediately. If the smoke is inhaled, gargle immediately.
(4) In case a large current continues to flow after a short circuit, in the worst case, the shorted-out
section may ignite. For safety, install a redundant circuit or a protective circuit, etc.
1.2-2 Wear-out failure (lifetime)
When lifetime exceeded the specified guarantee time of Endurance and Damp heat, electrolyte
might insulate and cause electric characteristic changed. This is called an open circuit. The electric
characteristics of capacitance and ESR may possibly change within the specified range in specifications
when it is used under the condition of the rated voltage, electric and mechanical performance. Please
note it when design.
1.3 Reduction of failure stress
When POSCAP is used within the rated voltage, it shows a stable characteristic, but it may be damaged
in a short circuit when an overvoltage, for instance, is applied. The time to reach the failure mode can be
extended by using POSCAP with reduced environment temperature, ripple current and applied voltage.
Failure rate
In the case of the endurance which is 105 °C 2000 h.
0.5 %/1000 h (Environment temp. : 105 °C, Rated voltage or Category voltage applied)
In the case of the endurance which is 105 °C 1000 h or 125 °C 1000 h.
1.0 %/1000 h (Environment temp. : 105 °C, Rated voltage or Category voltage applied)
In the case of the endurance which is 85 °C 1000 h.
1.0 %/1000 h (Environment temp. : 85 °C, Rated voltage applied)
1.4 Check the rated performance
After checking the operation and installation environments, design the circuit so that it falls within the rated
performance range stipulated in this delivery specification.
1.5 Operating temperature and ripple current
(a) Set the operating temperature so that it falls within the range stipulated in this delivery specification.
(b) Do not apply current that exceeds the allowable ripple current. Ripple current should be controlled so that
surface temperature of a capacitor do not exceed the rated temperature.
(For questions regarding TQC series, please contact us.)
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.

1.6 Leakage current
Even when the soldering conditions fall within the range of this delivery specifications, leakage current
increases a little on occasion. It also increases a little during high temperature storage, high humidity storage
and temperature cycling with no voltage applied. In cases such as these, leakage current will decrease by
applying voltage under the condition of below the POSCAP's maximum operating temperature.
The speed at which the leakage current is restored is increased by applying voltage when the POSCAP's
temperature is close to the maximum operating temperature.
1.7 Rapid charge and discharge limitation
Rapid charge and discharge are restricted (for maintainance of high-proof reliability).
A protective circuit is recommended for when a rapid charge or discharge causes excessive rush current
since this is main cause of short circuit and large leakage current. Use a protective circuits in case the rush
current value exceeds 20 A
½
.
Be sure to insert a protection resistor of about 1 kΩ for charge and discharge when measuring the leakage current.
½
When TH series use under the ambient temperature more than 105 °C : 10 A
TPU series : 10 A
2. Mounting
2.1 Protect circuit
The failure mode of POSCAP is the short mode. When it breaks down, short electric current flows to it.
POSCAP gives off heat by this short current.
Do the following consideration in design fully for the safety because it has a bad influence on the part around
POSCAP due to this heat.
∙ A protective circuit and a protective device are set up, so as to make the system safer.
∙ A diffuse circuit and so on is set up, so as to make the system safer such as that a machine may not
break down as to the single trouble.
2.2 Considerations when soldering
The soldering conditions are to be within the range prescribed in this delivery specification.
If the specifications are not followed, there is the possibility of degradation of electric characteristic and
lifetime when soldering is conducted under conditions that are harsher that those stipulated.
2.3 Others
POSCAP’s Electrical characteristics are affected by temperature and frequency fluctuations.
Design circuits after checking the amount of fluctuation.
3. Storage
It is necessary to set an environment to prevent a trouble at the time of soldering by the degradation of solder
ability or moisture's getting into the molding resin when POSCAP are stored.
Please make storage of POSCAP sealing up in the reel and storage bag at the time of delivery in the following
environment. Also, set storage period as 18 months or shorter.
Room temperature and room humidity (generally : 15 to 35 °C, 45 to 75% RH ) are desirable.
Place where POSCAP is not exposed by direct sunshine.
Please unseal storage bag just before mounting and be conscious that POSCAP in the storage bag is used up.
When remainder unfortunately occurs, return them to the storage bag once again and, please seal the unsealed
part by adhesive tape etc., including desiccants. Moreover, once and use it in time the storage bag is opened,
store POSCAP according to the table's Floor Life “Time” and “conditions”.
