Ultra Precision MELF Resistor
ORDERING INFORMATION
Components may be ordered by using either a simple clear
text ordering code, see “Type description and ordering
code”or Vishay BCcomponents’ unique 12NC.
Numeric Ordering code (12NC)
• The resistors have a 12-digit ordering code starting with
2312.
• The subsequent 4 digits indicate the resistor type,
specification and packaging; see the 12NC Ordering Code
table.
• The remaining 4 digits indicate the resistance value:
– The first 3 digits indicate the resistance value.
– The last digit indicates the resistance decade in
accordance with the 12NC Indicating Resistance
Decade table.

Ordering Example
The ordering code of an UMA 0204 resistor, value 4.75 kΩ
and TC05 with ± 0.05 % tolerance, supplied in antistatic
blister tape of 3000 units per reel is: 2312 113 44752.

Note
1. Readable coding of resistance values is restricted to values with three significant digits. For resistance values with more than three significant
digits, a non-readable sequential number will be issued by the factory for each requested combination of resistance value and tolerance.
