RESISTANCE VALUE
0.2 mΩ to 5 mΩ
There are 3~5 digits indicated the resistance value. Letter R/ U is decimal point.
Detailed coding rules of resistance are shown in the table of “Resistance rule of
global part number”.
(7) DEFAULT CODE
Letter L is the system default code for ordering only.
(Note)
ORDERING INFORMATION - GLOBAL PART NUMBER
Global part numbers are identified by the series, size, tolerance, packing
type, temperature coefficient, taping reel and resistance value.
ORDERING EXAMPLE
The ordering code of a PU3921,
value 0.0005Ω with ±1%
tolerance, 3W and high
temperature(275°C) supplied in
13-inch tape reel is :
PU3921FKNT30U5L
