8.3. Symbolic Marks
The symbolic marks for resistors and capacitors which used in this circuits are classified as
following
Table-1
and
8.3.1. RESISTORS
- Resistors without symbolic mark are FIXED CARBON FILM
RESISTORS (ERD-type).
- All resistors are 1/4 WATT, ±5 % TOLERANCE unless otherwise
designated in schematic diagrams.
