in products/production

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.

NOTE

1. All our RSMD products meet RoHS

compliant and Halogen Free. "LFP" of

the internal 2D reel label mentions

"Lead Free Process"

2. On customized label, "LFP" or specific

symbol can be printed

(5) TAPING REEL

07 = 7 inch dia. Reel

10 = 10 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”.
