. Resistor:

To differentite the units of resistors, such symbol as   and   are

used: the symbol   means 1000 ohm and the symbol   means

1000 Kohm and the resistor without any symbol is ohm-type
resistor. Beside, the one with “Fusible” is a fuse type.

 Capacitor:

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

 means micro-micro-farad and the unit of the capacitor without

such a symbol is 

 As to electrolytic capacitor, the

expression “capacitance/withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
