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
