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”.

ORDERING INFORMATION
-
GLOBAL PART NUMBER
Both part numbers are identified by the series, size, tolerance, packing
type, temperature coefficient, taping reel and resistance value.

RDERING EXAMPLE
The ordering code of a YC248
convex chip resistor array, value
1,000 X with ±5% tolerance,
supplied in 7-inch tape reel is:
YC248-JR-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
