Resistance Value Codes - Pioneer CT-F700 Service Manual

RESISTANCE VALUE CODES
Code
numbers
of
resistors used in Pioneer
equipment
Eue expressed in the following way:-
C o d e n u m b e r
R D 7 o P S 4 7 3 J N L
Type of resistor
P o w e r r a t i n g
S h a p e ( t u b u l e r )
R e s i s t a n c e ( c o d e v a l u e )
Tolerance
Low-noise marking
Furthermore, in the list of parts found in the
Service Manual, the resistance (code value) part of
the above code number is expressed as ! ! tr or
! ! t r ! .
Resistors included in the Service Manual list of
Parts I

E x . R D % P S r r I I
J N L
When ordering resistor components, first ascer-
tain the actual resistance value from the circuit
diagram, and then convert it into code no. form
as shown in the following examples.
For further details on code numbers. refer to
"Tuning Fork" VOL. 1.
