Differences from other capacitors
Structure of solid capacitors

7.Instantaneous charge and discharge
Instantaneous charging and discharging may cause leakage current of solid capacitor larger or even short defect:
1)Therefore, it is necessary to design a protective circuit in the following situations Impact current greater
than 10A.
2)Impact current greater than 10 times allowable max ripple current value.
In addition, when testing the product leakage current, set a 1KΩ protection resistor.

8.Prohibited circuits
Due to welding heat and mechanical stress during transportation, the leakage current of capacitor may increase. Please prohibit the following circuit designs.
1)High current and voltage holding circuit.
2)Coupling circuit.
3)Time constant circuit.

9.Circuit design
1)As electrical characteristics of capacitor change following the temperature and frequency changing, Please confirm this change before designing.
2)When connecting more than 2 capacitors in parallel, consider the current balance of them in the circuit design.
3)When two or more capacitors are connected in series, it is possible that capacitor overloads the voltage due
to differences in the loading voltage. Please consult us when using it.
4)Do not install heating parts around the capacitor or on the back of the printed wiring panel.

10.PCB design
Do not install solid capacitors around or on the heat source assemblies.
The diameter and spacing of mounting holes on PCB should match the diameter and pitch of capacitor lead.

11.Parallel circuit
When a solid capacitor is connected in parallel with another capacitor (liquid), because the solid capacitor has very low ESR, a large ripple current may be applied to it. In this case, please carefully select the solid capacitor.

The insulating coating outside the aluminum can of solid capacitor is not absolutely insulated. In addition, the aluminum can and negative lead are not insulated. When installing, please ensure that the aluminum can. positive and negative leads and PCB printing drawings are completely separated.

13.Restrictions on the working environment
1)Where water, salt water, oil can be dropped directly, and circuit boards that are prone to contraction, use is prohibited.
2)When harmful gases(H2S, sulfuric acid, nitric acid, ammonia, hydrochloric acid, etc.) are concentrated, use is prohibited.
3)Where ultraviolet, radioactive, ozone, etc. are radiated, use is prohibited.

14.Common failure mode
1)Accidental failure
Mainly caused by short defect of circuit, when current in the short circuit exceeds 1A, inner temperature of
capacitor will increase, and the internal pressure will increase, the sealing rubber will be raised or even opened,
then the capacitor will release harmful gas. At this point, it need to disconnect the circuit immediately and leave
this situation. In addition, overvoltage usage, ultra-high temperature usage, and excess rated ripple current usage,
will all lead to early failure or even short defect of the product.
2)Life failure
After a long period of useing, the characteristics of solid capacitor will decay, such as capacity drop, ESR rise,
etc.. When the service time exceeds the rated life, the characteristics of capacitor will deteriorate, which may lead
to the formation of an open circuit for electrolyte insulation.

Installation attentions
1.Preparation for installation.
1)Please do not reuse solid capacitors that have been installed and used.
2)Make sure that the capacitor to be installed does not exceed the storage period.
3)Please do not touch the pins of solid capacitor directly by hand.
4)Do not use a conductor to connect the positive and negative pins of capacitor. Do not let the capacitor contact
the conductive solution.
5)Confirm the capacity and working voltage of installed capacitor.
6)Please note the polarity of the capacitor.
7)Please prevent the capacitor from falling to the ground, otherwise do not use.
8)Please do not use the capacitor which body is pressed and deformed.
9)Please check that the pin of capacitor matches the PCB hole.
10)Please control the inserting strength and vibration strength.
11)Do not apply additional external force to the pins or body of capacitor .
12)When welding, please control the welding temperature and time, any of them over standard will cause leakage
current of capacitor increase.
13)When welding, make sure that hot components such as soldering tin and soldering iron are not in normal
contact with capacitor pins or body.

2.Attentions after welding
1)After welding, do not use external force to tilt, bend, twist capacitor pins or body.
2)Please do not grab the capacitor body to move the PCB.
3)When stacking welded PCB, prevent contact and friction between capacitor and capacitor, or with other
4)Do not let the solid capacitor welded to PCB withstand any external force.
5)When removing the solid capacitor from the circuit board with a soldering iron, it is recommended that the
removed capacitor be scrapped to avoid the affects of stress and overheating.
6)Do not touch the head of the welding iron to the solid capacitor body. Even the pin part can not stay in .contact
7)The leakage current may increase after the solid capacitor is welded, and the leakage current will gradually
decrease after the voltage is applied.

3.Electric iron welding


Storage Conditions and Environmental Requirements
1)Do not store solid capacitors in high temperature and high humidity. It is recommended to store temperature:
5-35 °C, humidity <75%.
2)To ensure solid capacitors favorable soldering performance, please do not open the packages and storage
period should not exceed 18 months.
3)For unpackaged products that have not been used at one time, please put them back into the bag and seal them.
The storage period for each type of product is as follows.
4)With the extension of storage time, the leakage current of the solid capacitor will increase. It can be repaired by charging the rated operating voltage (DC voltage) for 1 hour at 60-70 °C, and the capacitor should be connected in series with 1KΩ to protect the resistor.
5)Because solid capacitors contain some solid organic matter, metal materials and resin materials, please treat
them as work waste.
6)Our products and using materials are in compliance with EU restrictions on hazardous substances:
