What is the working life of the resistors in the 1206 package? The service life of electronic components such as chip resistors is actually difficult to determine. It does not have a specific use time. It is inevitable that failures will occur after long-term use. factors to judge. How do we know the working life of a resistor in a 1206 package? The following is a brief introduction. The resistance life of the 1206 package is related to the working environment temperature. Each chip resistor of different specifications has its working temperature range. Exceeding the range ac motor Capacitor will greatly affect the life. Its effect on life is also related to the duration. For example, the temperature of the chip resistance of the Samsung 0805 package is: the average temperature of 1h is 60°C, the average high temperature of 24h is 40°C, and the average annual high temperature is 30°C.
The low temperature viscosity of the impregnating agent in the 1206 package resistor increases, the internal voltage decreases, and the electrical resistance of the resistor decreases. If it is operated below its low allowable temperature, it will cause partial discharge inside the resistor, thereby accelerating the electrical aging of the resistor and reducing the actual service life of the resistor. In addition, if the chip resistor is operated above the high allowable temperature for a long time, the thermal aging of the chip resistor will be accelerated. Therefore, when we use resistors, we should choose chip resistors that are compatible with the actual operating ambient temperature.
When installing and using 1206 package resistors, pay attention to the ventilation, heat dissipation and radiation of the resistors under the conditions of use, so that the heat generated by the resistors during operation can be dissipated in time, and make every effort to work at high temperatures. When selecting materials, materials that are resistant to high temperature should be selected to reduce the impact on the circuit caused by current changes. When all the elements are guaranteed, the lines of the entire unit are guaranteed, then the service life of our chip resistors can also be guaranteed accordingly.
Chip resistors in 1206 packages are generally used and have a working life of about 10 years. However, if the ambient temperature is too high, or affected by factors such as chemical corrosion, the life will be shortened, generally shortened by 2-3 years. In severe cases, five or six Years are also available, and they even fail directly. Please note that this is only an estimate, the actual lifespan will be affected by many aspects, so it is for reference only.
