A lot of things happened in the past 2020. For the electronic components industry, the three major industry buzzwords in 2020 are [price increase], [out of stock], and [5G].
Generally speaking, it is nothing more than cost. In terms of size or weight, smd resistor are about 1/10 less than plug-in resistor.
The senior engineer should be close to a nominal value of the calculated value in the application circuit when selecting the SMD resistor value, which should be given priority
As a user of smd resistor, when you need a 50kΩ smd resistor during the design and production of the circuit, please consider whether you really need to deliberately seek a resistor of exactly 50kΩ. Because it is difficult to buy 50kΩ resis
