Notes On Schematic Diagram; Types Of Transistor And Led - Sharp WF-930Z(BK) Service Manual

WF-930Z
• Resistor:
To differentiate the units of resistors, The 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
an ohm resistor. The resistor designated "Fusible" is a fuse
type resistor.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means pico-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),(RH),(UJ): Temperature compensation
(ML): Mylar type
(S): Styrol type
