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.
l
Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means pico-fared and the unit of the capacitor
without such a symbol is microfared. As to electrolytic
capacitor, the expression “capacitance/withstand voltage” is
used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
