More and more customers will ask, do you have good quality and industrial grade? At this point, let's have a deeper understanding of what is industrial grade:

Military level working temperature of the device: - 55 ℃ ~ + 150 ℃ industrial-grade working temperature of the device: - 40 ℃ ~ + 85 ℃ commercial grade working temperature of the device: 0 ℃ ~ + 70 ℃ and some devices have a car of industrial-grade is - 40 ℃ ~ + 125 ℃. The computers and mobile phones on the market today are mostly commercially available, and it may be said that Microsoft's chips are military-industrial at the commercial level. The main difference is the temperature range.

How to select related passive components: TVS, patch diodes, transistors, MOS tubes, etc. Red, yellow, yellow, green and orange are generally 1.8v-2.4v; white, blue and green are generally 3.0v-3.6v. If they're both 20mA. There are three maximum/minimum/typical values in the general specification. However, if the rated current is the same, a constant current series is available. It may not be as bright for consistency reasons. How to do it: a red light has a voltage of 2.0v compared to a white light. For example, the voltage of the red light is 2.0v, and the voltage of the white light is 3.3v. The low-voltage ones tend to reach the maximum power. Conclusion: therefore, the parts are also relatively higher in the maximum power heating. According to R=(vcc-vf)/If in the circuit, it can be judged as heat dissipation volume: the higher the resistance value is, the higher the heating value of parts is. Therefore, selecting low Vf components can effectively reduce the power waste and ensure the heating problem of the whole components.
