Kingtronics Guidelines For Using Aluminum Electrolytic Capacitors

When using Aluminum Electrolytic Capacitors, please observe the following points to ensure optimum capacitor performance and long life.

1>DC electrolytic capacitors are polarized.

Make sure of the polarity which is marked on the body of the capacitor.
Application of the reversed voltage may cause a short circuit or damage to the capacitor.
Use bipolar capacitors when the polarity is not determined or unknown.
Note that DC electrolytic capacitors CAN NOT be used for AC application.

2>Bipolar capacitors
These capacitors are used only in pulse circuits as well as polarity reverse circuits, but not applicable in pure AC or high ripple current.

3>Do not apply voltage greater than the rated voltage
If a voltage exceeding the rated voltage is applied, the leakage current will increase, which will damage the capacitor.
Recommended working voltage is 70% – 80% of rated voltage.
Using capacitors at recommended working voltage prolongs capacitor life.

4>Do not allow excessive ripple current through the capacitor
The flow of ripple current greater than the permissible (rated) value will cause heating of the capacitor, which may decrease the capacitance and damage the capacitor.
Ripple current through the capacitor must be at or below the allowable level, generally not more than 80% of the rated current.

5>Use specially designed capacitors for the circuits where charge and discharge are frequently repeated.
In circuits subjected to rapid charge and discharge cycles, a capacitor may be damaged and its life may be shortened by capacitance decrease at higher temperature.

6. Operating temperature range.

The characteristics of capacitors change with the operating temperature.
The capacitance and leakage current increase and dissipation factor will decrease at higher temperatures. Usage at lower temperature will ensure longer life.

7. Temperature vs. Life.

The expected life of a capacitor is related to its ambient temperature.
Generally, if the ambient temperature is reduced 10℃, life is doubled at rated voltage.

8. Check operating frequency.

Electrolytes usually have their capacitance measured at 100 Hz. or 120 Hz.
However, remember that capacitance decreases and dissipation factor increase as the applied frequency becomes higher.

9. Capacitor Storage

Long periods of storage have virtually no effect on a capacitor’s capacitance and dissipation factor.
However, such periods can increase leakage current and decrease the capacitors withstand voltage.
Apply rated DC voltage treatment to the capacitors which have been stored for a long time.

10. The capacitor case is not insulated from the cathode terminal.

The capacitor’s case and cathode terminal connect through the electrolyte.
If the case is to be completely insulated, that insulation must be at the capacitor’s mounting point.

11. Do not apply excessive force to the terminals and leads.

An excessively strong force applied to the terminals and lead wires may cause leads to break or terminals to separate and, in turn, cause the internal contact to fail.

12. Cleaning of the circuit board after solder dipping.

Clean circuit boards to remove flux or other extraneous matter.
To ensure protection for the sleeve, its marking, and the capacitor’s sealing materials, the capacitor should never be washed or cleaned by halogenous agents or solvents such as trichlorethylene, xylene, acetone, etc.
Recommended cleaning solvents; Methanol, isopropanol ethanol, isobutene, petroleum ether, propanol and/ or commercial detergents.

13. Be cautious of the temperature and duration when soldering.
Soldering irons should be kept away from vinyl-insulated sleeves of capacitor.
When the capacitor is dipped in a solder bath, use at less than 260℃ and 10 seconds to avoid damaging the capacitor.

14. Hole positions on the circuit board.
When designing a circuit board, space the through-holes equal to the space between the capacitor’s lead wires.
If the spacing is either greater than or less than the capacitor’s leads, mounting will apply stress to the leads, causing short circuits, broken circuits, and increased current.
Also, through-holes on the circuit board as well as lead holes of post-process parts can result in solder splashing onto the vinyl sleeve causing damage.
Consider hole positions carefully.

Kingtronics Share 3 Tips to Make Winter Wake-Ups Easier

Now that winter’s here, it’s more difficult to get up in the morning. In fact, more than half of us admit getting up during winter is a ‘struggle’. Unsurprisingly, Monday mornings are the hardest. So what little changes could you make? Here are 3 top tips to give you that extra ‘morning motivation’ boost:

1> Have a drink.

Drinking water as soon as you wake up will help stimulate the body and help you stay awake.

Kingtronics-Have-a-drink

2> Do something active.

You may not have the time or energy for a full-blown exercise routine every morning, but get your body moving somehow such as forcing yourself to wiggle around under the covers.

Kt-Do-something-active

3> Remind yourself of what you have to do.

Noting your to-do list on a small whiteboard or a piece of paper kept on the nightstand, which will help you feel at night like you have those things handled, or at least noted, for the following day, and it will give you more reason to get up in the morning.

Kingtronics-Remind-yourself

If none of this works, there’s the obvious tip of setting the alarm clock across the room. *^__^*
