SMX Style for High Temperature Applications up to 200ºC
SMX-style, stacked Switch Mode Power Supply Capacitors (SMPS) utilizing
Multilayer Ceramic (MLCC) construction are ideally suited for high temperature
applications up to 200ºC. This product is intended for downhole oil exploration,
including logging while drilling, geophysical probes, as well as space and aerospace
electronics. The high temperature solder utilized in the construction of SMX-style
parts assures reliable operation in harsh environments. The wide product offering
provides designers a solution for high capacitance value and high voltage capaci-
tors rated at 200ºC. The SMX-style capacitors are ideally suited for applications as
DC filters in high power, high frequency motor drives, high pulsed-current circuitry,
as well as low power electronics.
SMX-style, SMPS capacitors are characterized with excellent performance in
comparison to wet tantalum products. The main benefits of SMX-product over wet
tantalum capacitors include:
• Much lower ESR and lower losses
• Excellent capacitance retention with frequency
• Excellent high frequency performance
• Low DC leakage current
• Much higher current handling capabilities
