Cautions
Caution when replaceing chip (leadless) parts.
Do not re-use the removed parts, but use new parts.
Be careful that the negativ side of the tantalum capacitors are susceptible to heat.
Voltage indications are omitted for capacitors other than chemical and tantalum capacitors with a
dielectric strength of 50 V or less.All units are
Chip resistors without indication are 1/10 W.
