Global Capacitor Part Number Definition
Johanson has instituted a new "Global Part Numbering" (GPN) Definition.
Only the part number is changing. The parts are produced with the exact same materials, manufacturing processes, manufacturing controls, dimensions, physical attributes and testing as the parts supplied with the legacy part numbers.
- The GPNs will be phased in over the next several years and are planned to be completed by January 1, 2026.
- We will continue to quote and accept orders with the current (legacy) part numbers throughout this period.
- Beginning January 1, 2022, all samples will be provided with the GPN.
- Updates associated with this change will occur periodically.
- A database for the approximate 1.7 million crosses can be accessed at: Global Capacitor Part Number Search

Subfamily
X For all SMPS Subfamilies, replace the x with the number of chips. For example, the code for SMPS P-Series PME with 4 chips is M4. See SMPS Subfamilies tab for the complete list.

201 = 200V
602 = 6,000V
Special CodeZZZ = Special Code
3 numeric values in the voltage field – No "R" in the 3 digits – used for values greater than or equal to 10 Volts.
1st two digits are significant; third digit denotes number of zeros:
- 100 = 10 Volts
- 101 = 100 Volts
- 402 = 4000 Volts
With "R" in the 3 digits – used for capacitance values less than 10 Volts:
- R = decimal point
- 6R3 = 6.3 Volts
