Resistance value in three-digit designation system is marked
on the glasscoat. Illustrated is a resistor of 15KΩ. Four-digit
resistance designation system is applied to RMC 1/8 and E-96
Series. For example, 1502 designated 15KΩ. (The last digit
specifies the number of zeros.)
* For 1%, a 3-digit alpha-numeric
marking system is used. Contact
factory for details.
