SCOPE
ORDERING INFORMATION - GLOBAL PART NUMBER & 12NC
This specification describes
RT0402 to RT2512 high precision -
high stability chip resistors with
lead-free terminations made by
thin film process.
Both part numbers are identified by the series, size, tolerance, packing
type, temperature coefficient, taping reel and resistance value.

6 RESISTANCE VALUE
reliability
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.
ꢀ Saving of PCB space
ꢀ None forbidden-materials used

Letter L is system default code for order only (Note)
ORDERING EXAMPLE
Resistance rule of global part
number
The ordering code of a RT0603 chip
resistor, TC 50 value 56 X with
±0.5% tolerance, supplied in 7-inch
tape reel is: RT0603DRE0756RL.

Example
1R = 1 Ω
1R5 = 1.5 Ω
9R76 = 9.76 Ω
XRXX
(1 to 9.76 Ω)
NOTE

10R = 10 Ω
1. All our RSMD products meet RoHS
compliant and Halogen Free. "LFP" of
the internal 2D reel label mentions
"Lead Free Process"
(10 to 97.6 Ω)
97R6 = 97.6 Ω
XXXR
(100 to 976 Ω)
100R = 100 Ω
XKXX
(1 to 9.76 KΩ)
1K = 1,000 Ω
9K76 = 9760 Ω
2. On customized label, "LFP" or specific
symbol can be printed
XMXX
1M = 1,000,000 Ω
(1 to 9.76 MΩ)
9M76= 9,760,000 Ω
