Conductive Polymer Tantalum Solid Capacitors

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

こ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*.

Be sure to insert a protection resistor of about 1 kΩ for charge and discharge when measuring the leakage

current.

* When TH series use under the ambient temperature more than 105 °C : 10 A, TPU series : 10 A

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.

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 the moisture proof bag at the time of delivery in the following

environment. Also, set storage period of unopened as 18 months or shorter after shipment from factory.

・ 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 the moisture proof bag just before mounting and use up POSCAP in the moisture proof bag.

Storage conditions after opening the moisture proof bag are as follows.

POSCAP is not compatible with JEDEC J-STD-020, J-STD-033
