[1] Notes on schematic diagram
•
Resistor:
Letters K and M are prefixed to ohm (unit of resistance).
K means 1000 ohms and M means 1000 kohms.
•
Capacitor:
P is an abbreviation for "pico" and a farad (unit of capacitance)
without P means "microfarad". Expressions "capacitance/withstand
voltage" are used for electrolytic capacitors.
(CH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(S): Styrol type
(PP): Polypropylene type
