Effectively solve the problem that chip resistors are vulnerable to acid corrosion

For a patch resistor product used around an automobile engine, an abnormal resistance phenomenon occurs in some cases, resulting in a problem with the entire product function. Meilong Electronics engineers explained the possible reasons for this situation. This kind of situation is due to the fact that common patch resistors are easily affected by the vulcanization environment. What should we do if we encounter this situation?

To this end, the R & D team of Maloney Electronics made a special process of anti-vulcanization chip resistor by adding vulcanization-resistant materials to the electrode to effectively solve the influence of the chip resistor under the vulcanization environment. Let us together Learn more about this special anti-vulcanization chip resistor.

Anti-vulcanization chip resistor (AS series) function

High-concentration sulfur gas is one of the main extremes affecting electronic products. Electronic products exposed to high concentrations of sulfur gas such as industrial control systems, sensors, instrumentation equipment, communication base stations, etc., sulfur gas will be from the electrode of the patch resistor. The gap between the protective layer and the protective layer is combined with the silver material of the terminal electrode of the chip resistor to produce silver sulfide, which results in the insulation of the chip resistor, thereby causing the electronic device to fail or even become dangerous. The anti-vulcanization chip resistor has high anti-vulcanization performance, can work normally and stably in a sulfur-containing environment, has outstanding performance and long service life, and can effectively solve the effect of corrosion and vulcanization of electronic components.
