CHIP RESISTOR
阻值代码 Resistance Value Code
所有电流检测电阻全尺寸 统一采用四位数阻值代码表示。
All resistance value code of current sensing thick film chip resistor used four digits.
例
Example
RBF03MR010FT
四位数代号表示,如:R010=10mΩ ;30M1=30.1m
To use four digits code represent resistance value ,

标记 Marking
E-24
For the chip resistor (0508
resistance value belongs to E24 and E96 series, we suggest preferentially use four digits.

≤0402产品不印刷标记。
For the chip resistor (≤0402), there is no mark on the glass side.
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。
