Growing in the southern region of China, the sudden drop in temperature, maybe you think it is amazing. People could still wear T-shirts and shorts last month. This week, cold air hit and dropped by 10℃-20℃ overnight.

Last month, we had a warm activity in Guangxi Province, where we shared some clothes, shoes and blankets for children in mountainous areas. Now they can wear them all, and also can cover the blankets. We hope that students in schools will be warmer this winter.

Recently, we have received many letters from these students, some students express gratitude, while others tell us their needs. Kingtronics will do our best to meet the needs of students and provide them with a happy, healthy, and joyful childhood

1. DC electrolytic capacitors can only be used on DC circuits, and their polarity must be marked in an appropriate position or next to the conductor/terminal.
2. If the polarity of the circuit is unclear or unclear in the circuit loop, it is recommended to use a non-polar electrolytic container.
3. The working environment temperature of electrolytic capacitors should not exceed the specified operating temperature range.
4. Electrolytic capacitors should be stored in low temperature and dry places. If the storage period is long, they should be re aged with rated voltage before using.
5. The ripple current passing through the electrolytic capacitor should not exceed its allowable range. If it exceeds the specified value, electrolytic capacitors with high ripple current resistance should be selected.
6. When in use, the working voltage of the electrolytic capacitor should not exceed its rated voltage.
7. High temperature heating devices such as electric soldering irons should be kept at an appropriate distance from the plastic shell of the electrolytic capacitor to prevent the plastic sleeve from cracking due to overheating.
8. When welding electrolytic capacitors, the welding time and temperature should not exceed 10 seconds and 260 degrees Celsius.
9. Applying excessive force to the guide pins and terminals will damage the internal structure of the electrolytic capacitor

The use principle of Varistor is that after it is connected to the protected equipment, it cannot affect the normal operation of the equipment, and can effectively implement instantaneous overvoltage protection for the equipment. Therefore, in addition to the technical parameters of Varistor, the following issues should be considered in the actual selection:

(1) Selection of voltage sensitivity
Considering the deviation between the actual Varistor voltage and the nominal voltage (1.1~1.2 times of the nominal voltage should be considered), the possible fluctuation range of the power supply voltage in the AC circuit (1.4~1.5 times of the rated voltage should be considered), and the relationship between the peak value of the AC voltage and the effective value (1.4 times should be considered), the Varistor with a voltage sensitive of 2.2~2.5 times of the rated voltage should be selected. In DC circuits, Varistor with a voltage sensitive of 1.8~2 times the rated value of DC voltage are often selected.

⑵ Selection of flow capacity
In principle, the selection should be based on the maximum transient surge current that may be experienced, but achieving this is difficult. In practice, the selection of Varistor is based on the use occasion or the test grade specified in the product test standard.

According to the former, 1kA (8/20 μ S current wave) can be used for the protection of silicon controlled rectifier; 3kA is used for surge absorption in electrical equipment; 5kA is used for overvoltage absorption of lightning strikes and electronic equipment; 10kA is used for protection against lightning strikes. According to the latter, the commonly used composite wave (1.2/50 generated when the generator is open circuit output) μ Voltage wave of s; 8/20 generated during short-circuit output μ Current wave of s; The internal resistance of the generator is 2 Ω to assess the equipment's ability to withstand lightning surge interference online. During the 4kV test, the maximum current absorbed by the protector can reach 2kA; For the 6kV test, the maximum absorbed current is 3kA. However, in actual selection, the flow capacity of the selected Varistor should also be appropriately increased. Because Varistor with large current passing capacity should have relatively small residual voltage drop when absorbing surge current of the same size; At the same time, there is also a large protection margin for the selected Varistor.

⑶ Inherent parasitic capacitance
Varistor has an inherent capacitance problem. Its value ranges from hundreds to thousands of pF according to the difference of external dimensions and nominal voltage. The inherent capacitance of Varistor determines that it is not suitable for use in high-frequency occasions, or it will affect the normal operation of the system; Suitable for use in power frequency systems, such as for protection of power incoming lines, protection of thyristor rectifiers, etc.

The instantaneous power of Varistor is relatively large, but the average continuous power is very small, so it cannot work in the conduction state for a long time.https://www.kingtronics.com/Metal-Oxide-Varistor/XKT-Metal-Oxide-Varistor.html
