贴片电阻阻值标示识读方法

1、贴片电阻阻值标注方法1E-24标注方法E-24标注法有两位有效数字，精度在±2%（-G），±5%（-J），±10%（-K）（1）常用电阻标注XXY：XX代表底数，Y代表指数例如：470 = 47，103 = 10k，224 = 220k（2）小于10欧姆的电阻的标注用R代表单位为欧姆的电阻小数点，用m代表单位为毫欧姆的电阻小数点。例如：1R0 = 1.0，R20 = 0.20，5R1 = 5.1，R007 = 7.0m，4m7 = 4.7m2E-96标注方法E-96标注法有三位有效数字，精度在±1%（-F）(1) 常用电阻标注 XXXY： XXX代表底数

2、，Y代表指数例：4700 = 470，1003 = 100k，2203 = 220k(2) 小于10欧姆的电阻的标注 用R代表单位为欧姆的电阻小数点，用m代表单位为毫欧姆的电阻小数点。 例如：1R00 = 1.00，R200 = 0.200，5R10 = 5.10，R007 = 7.00m，4m70 = 4.70m+(3) E-96 Multiplier Code标注法 XXY：XX 代表底数的代码，具体数值可从Multiplier Code表中查找，Y 代表指数的代码，具体数值也要从Multiplier Code表中查找。例如：18A = 150，02C = 10.2k精密电阻阻值表精密贴片

3、电阻是用代码来计算的，如01C就是10K。下面是代码，就像查字典一样。又例如：10欧的电阻用代码01X表示，仔细看下表你就会明白的。标准阻值表 E-96 0603F(+1%) Standard Resistance Table标准阻值表1E-96阻值代码阻值代码阻值代码阻值代码阻值代码阻值代码1001X10001A1.00K01B10.0K01C100K01D1M01E10.202X10202A1.02K02B10.2K02C102K02D10.503X10503A1.05K03B10.5K03C105K03D10.704X10704A1.07K04B10.7K04C107K04D1105X1
