Notes On Schematic Diagram; Type Of Transistor And Led - Sharp MD-X60 Service Manual

MD-X60
• 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
(P.P.): Polypropylene type
• Schematic diagram and Wiring Side of P.W.Board for this model are
subject to change for improvement without prior notice.
