SMPS Stacked MLC Capacitors 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 Typical Extended Temperature TCC Characterization of C0G, SMPS Capacitors Test conditions: 1 Vrms, 1 kHz, 0 VDC bias -1.0 -0.8 -0.6 -0.4 -0.2 0.0 0.2 0.4 0.6 0.8 1.0 -75 -50 -25 0 25 50 75 100 125 150 175 200 Temperature (ºC) Percentage Capacitance Change RC Product (/H9024*F) Typical Extended Temperature IR Characterization of C0G, SMPS Capacitors 100 1000 10000 120 130 140 150 160 170 180 190 200 Temperature (ºC) RC Product (/H9024*F) Typical Extended Temperature IR Characterization of X7R/X9U, SMPS Capacitors Temperature (ºC) 100 1000 10000 120 130 140 150 160 170 180 190 200 Typical Extended Temperature TCC Characterization of X7R/X9U, SMPS Capacitors Test conditions: 1 Vrms, 1 kHz, 0 VDC bias Temperature (ºC) -100 -80 -60 -40 -20 -75 -50 -25 0 25 50 75 100 125 150 175 200 Percentage Capacitance Change
