Notes On Schematic Diagram - Sharp MD-S301 Service Manual

MD-S301/S301W
• 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 electro-
lytic capacitor, the expression "capacitance/withstand volt-
age" is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
