For chip resistor products used around car engines, under certain circumstances, the phenomenon of abnormal resistance will occur, causing problems in the function of the entire product. In view of this situation, the engineers of Meilong Electronics explained the possible causes. This kind of situation is caused by the fact that ordinary chip resistors are easily affected by the vulcanization environment. So what should we do in this situation? To this end, the R & D team of Meilong Electronics has made a special process of anti-sulfur chip resistors by adding sulfide-resistant materials to the electrodes to effectively solve the impact of chip resistors in the vulcanized environment. Let us together Learn more about this special anti-sulfide chip resistor. The role of anti-vulcanization chip resistors (AS series) High-concentration sulfur gas is a major extreme situation that affects electronic products. For electronic products exposed to high-concentration sulfur gas areas such as industrial control systems, sensors, instrumentation equipment, communication base stations, etc., sulfur gas will come from the electrodes of the chip resistors The gap with the protective layer enters and combines with the silver material of the terminal electrode of the chip resistor to produce silver sulfide, which leads to the insulation of the chip resistor, which makes the electronic device failure or even dangerous. Anti-vulcanization chip resistors have high anti-vulcanization performance, can work normally and stably in sulfur-containing environments, have outstanding performance and long life, and can effectively solve the effect of corrosion and vulcanization of electronic components.

Material storage and transportation requirements Non-naked packaging Temperature requirement: 5 ℃ ~ 35 ℃ Humidity requirement: 25% ~ 75% Shelf life: 1 year from shipment Anti-extrusion / collision: prevent the outer box or reel from deforming during handling and storage other request Moisture-proof: Control the storage temperature and humidity. It is recommended to confirm whether the ambient temperature and humidity are within the required range every day. If an abnormality is found, you can use a dehumidifier or air conditioner to adjust it. Note: Bare packaging means that the original packaging of the material is split and then stored. Anti-extrusion / collision: prevent the outer box or reel from deforming during handling and storage. Finally, it should be pointed out that the product performance and welding connection may deteriorate when stored in a high static environment or in sunlight, rain, snow or condensation. If you have any questions about the product, you are welcome to consult our customer service staff, we will Provide you with professional, timely and patient service.
The UV light with ozone can kill the bacteria, viruses, allergens, mold more efficiently. And it can purify air and remove odor 360 degree, providing a healthier living environment to your family. (Note: ozone contains odor and should be ventilated for 45 minutes after disinfection.)
Does UV light really sanitize?

A: Ultraviolet-C (UVC) light emitted by these hand-held devices is noted for its germicidal abilities, but it's not clear whether using one of them prevents infections in people. ... And even if the device can kill, say, 99 percent of disease-causing bacteria, that may still leave enough microorganisms to cause infection.
