• Manufacturer Part Number: CMA0204
• Description: High Pulse Load MELF Resistor
• Manufacturer: Vishay Intertechnology

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
• The subsequent 4 digits indicate the resistor type,
• The remaining 4 digits indicate the resistance value:
