CHIP RESISTOR
阻值代码 Resistance Value Code
所有厚膜电阻的阻值代码与其标记是相对应的。
All the resistance value code of thick film chip resistor is corresponding with the marking .
标记 Marking
E-24系列(≥0603、≥±5%):采用三位数字表示,前二位表示电阻值有效数字,第三位表示乘以10的次方数。
E-24 series: Express resistance value on the glass side with three digits, the first tow digits
should be significant and the third one denote number of zeros.
例
For example:
30KΩ
33Ω
E-24系列 (0603、≤±1%):在三位数字标记下方增加下横线识别
。
E-24 series(0603、≤±1%): Three digits with one short bar under marking letter.
例
For example:
E-96系列和E24系列(≥0805、≤±1%
▲ 采用四位数字表示,前三位表示电阻值有效数字,第四位表示乘以10的次方数。
E-96 series & E-24 series ≥0805、≤±1%
):
(
):
Express the resistance value with four digits, the first three digits are significant figures and the fourth
de notes the number of zeros.
例
For example:
100K
Ω
E-96系列 (0603、≤±1%):
▲采用三位代码表示,前二位表示E-96系列阻值代码,后一位字母表示乘数代码(见表三和表四)。
he resistance value with three code, the first two digit code denote the resistance of E-96 series,
Express t
and the third code of letter denote the multiplier
(see the table three and four ).
例
For example:
2MΩ
小数点以“R”表示 The decimal point should be expressed by“R” .
For example:
跨接电阻以“ ”表示 The jumper should be expressed by “0”
例 For example:
例
22

≤0402产品不作标记 For the chip resistor( ≤0402), there is no mark on the glass side.
For example:
例
非IEC标准系列的电阻值标记表示方法:一般以最接近IEC E24系列标称阻值的标记表示方法。
For the resistance which don't belong to IEC serial, use the resistance of IEC serial which is most
close to the required resistance of non-IEC serial for replacement.
客户对标记有特殊要求时,则按照协商的结果印刷标记。
To get agreement by both party if there special requirement for the marking.
