**Conductive Polymer Tantalum Solid Capacitors** 

## **Application Guidelines (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) Coupling circuit 

- (3) Time constant circuits 

- (4) Circuits greatly affected by leakage current 

- (5) 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 %* / 1000 h (Confidence level : 60 %) based on JIS C 5003. 

The mainly failure modes are as follows. 

- 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. 

- (a) If POSCAP emit smoke, turn off the main power of the equipment. In this case, keep your face and  hands away from the area. 

- (b) It may take a few seconds to a few minutes before POSCAP emits smoke by the situation. When using a protection circuit, design the product so that it operates during this period. 

- (c) If the smoke comes into eyes, rinse immediately. If the smoke is inhaled, gargle immediately. 

- (d) In case a large current continues to flow after a short circuit, in the worst case, the shorted-out section may ignite. Consider safety designs such as redundant design and protection circuits. 

## **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 rated capacitance values and the electrical characteristics values such as ESR specified in the characteristics list are factory default values. Please carefully design a circuit since rated capacitance values and the electrical characteristics values 

may change (increase) beyond the specified values under the conditions of rated voltage/temperature and electrical/mechanical performances. 

## **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** 

- (1) Set the operating temperature so that it falls within the range stipulated in this delivery specification. 

- (2) 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.) 

- (3) The ESR values specified in the characteristics list are factory default values. 

ESR values may change (increase) beyond the specified values depending on the customer's use conditions.

**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. 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. 

## ~~a~~ **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 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. 

||Floor life|Floor life|
|---|---|---|
|Level|Time|Conditions|
|2a|4 weeks|≦30℃/ 60 %RH|
|3|168 hours|≦30℃/ 60 %RH|
|5|48 hours|≦30℃/ 60 %RH|
