3MM ceramic trimmer capacitor is the parts that its capacitance can be changed freely, which is mounted directly on the printed circuit board with a provision to vary its value using a small screwdriver.

Murata TZS2 series (ultra-small and thin type with external dimensions of 2.2(W) x2.7 (L) x0.95 (H) mm) have been discontinued and have not competitor sell the same product. KKT series can cross reference when users change the PCB pattern size to 3MM. KKT series are high durability from vibration, dust, moisture and flux, which is designed for reflow soldering. Small size with external dimension of 3.2(W) x 4.5(L) x 1.5(T) mm

A. Because the capacity of electrolytic capacitors is much larger than that of general fixed capacitors, the appropriate range should be selected for different capacities when measuring. In general, the capacitance between 1 ~ 47μF can be measured by R × 1k, and larger than 47μF can be measured by R × 100.
A、因為電解電容的容量較一般固定電容大得多，所以，測量時，應針對不同容量選用合適的量程。一般情況下，1～47μF間的電容，可用R×1k擋測量，大於47μF的電容可用R×100擋測量。

B. Connect the red meter to the negative pole and the black meter to the positive pole. At the moment of contacting, the pointer deflects to the right largely (for the same resistance, the larger the capacity, the larger the swing), and then gradually turn left until it stops at a certain point, which is  the forward leakage resistance that is slightly larger than the reverse leakage resistance. The leakage resistance should generally be above hundreds kΩ, otherwise, it will not work properly. In the test, if there is no charging phenomenon in the forward direction and the reverse direction, that is the needle does not move, which means that the capacity disappears or the internal circuit is broken. If the resistance measured is small or zero, it indicates that the capacitor is large leakage resistance or has been broken and damaged, cannot be use any more.
B、將萬用表紅表筆接負極，黑表筆接正極，在剛接觸的瞬間，萬用表指針即向右偏轉較大偏度(對於同一電阻擋，容量越大，擺幅越大)，接着逐漸向左迴轉，直到停在某一位置。此時的阻值便是電解電容的正向漏電阻，此值略大於反向漏電阻。電解電容的漏電阻一般應在幾百kΩ以上，否則，將不能正常工作。在測試中，若正向、反向均無充電的現象，即錶針不動，則說明容量消失或內部斷路;如果所測阻值很小或為零，說明電容漏電大或已擊穿損壞，不能再使用。

C. For the electrolytic capacitor whose signs are unknown, it can be discriminated by using the above method. Frist, measure the leakage resistance at randomly and remember its swing. Then, exchange the test leads to measure a resistance. In two measurements, the large resistance is the forward connection, that is the black meter is connected to the positive pole and the red one is connected to the negative pole.
C、對於正、負極標誌不明的電解電容器，可利用上述測量漏電阻的方法加以判別。即先任意測一下漏電阻，記住其大小，然後交換表筆再測出一個阻值。兩次測量中阻值大的那一次便是正向接法，即黑表筆接的是正極，紅表筆接的是負極。

D. Via the multimeter to charge the electrolytic capacitor from the positive and the reverse side, the capacity can be estimated according to the magnitude of the swinging.
D、使用萬用表電阻擋，採用給電解電容進行正、反向充電的方法，根據指針向右擺動幅度的大小，可估測出電解電容的容量。

Labor day pays tribute to the contributions and achievements of American workers, was created by the labor movement in the late 19th century and became a federal holiday. 

Now, Labor day is an international holiday in many countries worldwide. It usually occurs around 1st May, but the date varies across countries.

Taking a break is for accomplishing a longer journey. 

Happy Labor day! Enjoy your holidays!

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.
