GLOBAL PART NUMBER (PREFERRED)
YC 158/358 X X X X XX XXXX L
(1) (2) (3) (4) (5) (6) (7)
(1) SCHEMATIC
L = L-type (for YC358)
T = T-type (for YC158/358)
(2) TOLERANCE
J = ±5%
(3) PACKAGING TYPE
R = Paper taping reel (YC158)
K = Embossed taping reel (YC358)
(4) TEMPERATURE COEFFICIENT OF RESISTANCE
– = Base on spec
(5) TAPING REEL
07 = 7 inch dia. Reel
13 = 13 inch dia. Reel
(6) RESISTANCE VALUE
There are 2~4 digits indicated the resistor value. Letter R/K/M is decimal point, no need
to mention the last zero after R/K/M, e.g.1K2, not 1K20.
Detailed resistance rules show in table of “Resistance rule of global part number”.
(7) OPTIONAL CODE
L = optional symbol (Note)
ORDERING INFORMATION
-
GLOBAL PART NUMBER & 12NC
Both part numbers are identified by the series, size, tolerance, packing
type, temperature coefficient, taping reel and resistance value.
SCOPE

- Resistor element and glass are
exempted by RoHS
Reducing environmentally
hazardous wastes
High component and equipment
reliability
Saving of PCB space
None forbidden-materials used
in products/production
Halogen Free Epoxy
ORDERING EXAMPLE
The ordering code of a YC158/358T
T-type chip resistor network,
value 1,000 X with ±5%
tolerance, supplied in 7-inch tape
reel is: YC158/358TJR-071K(L).
NOTE
1. All our RSMD products meet RoHS
compliant. "LFP" of the internal 2D reel
label mentions "Lead Free Process"
2. On customized label, "LFP" or specific
symbol printed and the optional "L" at
the end of GLOBAL PART NUMBER /
12NC can be added (both are on
customer request)
