303丝印0805电阻多大

303丝印表示的是电阻的一种封装类型，0805则是尺寸代码，用于描述电阻的大小。0805尺寸通常指的是电阻的长宽尺寸，其中08代表宽度为0.8毫米，05代表长度为1.2毫米。对于0805尺寸的303系列电阻，具体的阻值范围并没有直接对应，因为不同厂商可能会生产不同阻值的0805电阻。

303系列通常是一组常见的电阻值系列，比如100欧姆、1k欧姆、10k欧姆等，但你需要查看具体的产品规格书或者电子元件数据表才能得到303丝印0805电阻的确切阻值。如果你想知道某个特定阻值的303系列0805电阻，应该提供完整的型号或查阅相关资料。

30B丝印的贴片电阻，阻值是多少

30B是贴片电阻的规格代码，其中30代表电阻的数值，后面的B表示数量级，即10的0.5次方，即3.162。因此，30B丝印的贴片电阻的电阻值为30乘以3.162，约为94.86欧姆，精度为±0.1欧姆。需要注意的是，贴片电阻的丝印编码方式可能因厂商和产品系列而有所不同，因此在选择和使用贴片电阻时，最好参考贴片电阻的规格书，以确保正确理解贴片电阻的数值。
