AVX Introduces 25V Rating and Extended Capacitance Range to its Industry Leading MIL-PRF-49470 SMPS Capacitor Family

AVX Corporation has expanded the voltage and capacitance range of its MIL-PRF-49470-qualified SMPS Series stacked MLC capacitors by adding a 25V capacitor to the original 50-500V offering.  The new 25V SMPS capacitor currently features standard MIL-PRF-49470 Level “B” reliability; however, a parallel component with T-Level reliability for space applications is under qualification. 

Designed for high-current, high-power, and high-temperature applications, AVX’s MIL-PRF-49470 SMPS capacitors exhibit very low ESR and ESL and can withstand temperatures ranging from -55°C to +125°C.  Primarily used in the input/output filters of high-power and high-voltage power supplies, as well as in bus filters and DC snubbers for high-power inverters, the SMPS Series is also ideal for DC/DC converters, general and switched-mode power supplies, aerospace instrumentation panels, and a variety of hybrid power and military applications.

EMC & eMobility

For a company embarking on EMC testing for either component or vehicle-level testing of their EV products, it is necessary first to have a good understanding of the EMC regulatory situation.

AVX’s SMPS Series capacitors are available in six case sizes and with a variety of through-hole and surface-mount lead options in order to both provide effective mechanical decoupling of the ceramic chips from the board and minimize stress during board flexing, vibration, and temperature cycling in a broad range of applications.  Lead frames are attached to the chips using high temperature solder, so there is no risk of solder reflow during board assembly.  SMPS Series capacitors are also available in both unencapsulated (MIL-PRF-49470/1) and encapsulated (MIL-PRF-49470/2) packaging technologies, providing design engineers with an enhanced reliability and durability option.
