Mini-Switchmode® Capacitors
JDI's Mini-Switch Mode® ceramic capacitors combine the advantages of high capacitance found in tantalum capacitors with very low ESR performance of ceramic capacitors. The "J" and "L" lead configurations replace 1825 and 2225 SMT chips to provide stress relief and prevent cracking due to thermal cycling or mechanical board flexing. Another plus of the J-lead style is that this configuration allows use of the same solder lands as the SMT chips. See the Switch-Mode section for larger values. See also the Technical Notes on soldering and handling and suggested solder lands.

The legacy info below is for reference only.
Johanson has instituted a new Global Part Numbering (GPN) system.
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 2 million crosses can be accessed at: https://www.johansontechnology.com/pn-search
