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 Stacked Switch-Mode section for larger
values. See also the Technical Notes on soldering and handling
and suggested solder lands.
FeatureS
• High Capacitance, Small Size
• Low ESR/ESL
• Leadframe reduces thermal & mechanical stress due to
board flexure and TCE mismatch
applicationS
• DC-DC Converters
• Power Supply Input & Output Filters
