• Resistor:

To differentiate the units of resistors, such symbol as K and

M are used: the symbol K means 1000 ohm and the symbol

M means 1000 kohm and the resistor without any symbol is

ohm-type resistor. Besides, the one with “Fusible” is a fuse

type.

• Capacitor:

To indicate the unit of capacitor, a symbol P is used: this

symbol P means micro-micro-farad and the unit of the

capacitor without such a symbol is microfarad. As to

electrolytic capacitor, the expression “capacitance/withstand

voltage” is used.

(CH), (TH), (RH), (UJ): Temperature compensation

(ML): Mylar type
