SMPS Stacked MLC Capacitors SMX Style for High Temperature Applications up to 200C SMX-style, stacked Switch Mode Power Supply Capacitors (SMPS) utilizing Multilayer Ceramic (MLCC) construction are ideally suited for high temperature applications up to 200C. 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 200C. 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 Typical Extended Temperature TCC Characterization of VHT, SMPS Capacitors Characterization of C0G, SMPS Capacitors Test conditions: 1 Vrms, 1 kHz, 0 VDC bias Test conditions: 1 Vrms, 1 kHz, 0 VDC bias 1.0 20 0.8 0 0.6 -20 0.4 -40 0.2 -60 0.0 -0.2 -80 -0.4 -100 -80 -40 -20 0 20 40 60 80 100 120 140 160 180 200 -0.6 Temperature (C) -0.8 -1.0 -75 -50 -25 0 25 50 75 100 125 150 175 200 Temperature (C) Typical Extended Temperature IR Characterization of Typical Extended Temperature IR Characterization of C0G, SMPS Capacitors VHT, SMPS Capacitors 1000 10000 1000 100 100 10 10 150 160 170 180 190 200 120 130 140 150 160 170 180 190 200 Temperature (C) Temperature (C) 37 RC Product ( *F) Percentage Capacitance Change RC Product ( *F) Percentage Capacitance ChangeSMPS Stacked MLC Capacitors SMX Style for High Temperature Applications up to 200C ELECTRICAL SPECIFICATIONS Temperature Coefficient C0G: A Temperature Coefficient 0 30 ppm/C, -55 to +200C VHT: C Temperature Coefficient 15%, -55C to +125C +15% - 56%, -55C to +200C Capacitance Test (MIL-STD-202 Method 305) 25C, 1.00.2 Vrms (open circuit voltage) at 1KHz Dissipation Factor 25C C0G: 0.15% Max 25C, 1.00.2 Vrms (open circuit voltage) at 1KHz VHT: 2.5% Max 25C, 1.00.2 Vrms (open circuit voltage) at 1KHz Insulation Resistance 25C (MIL-STD-202 Method 302) 100K M or 1000 M-F, whichever is less.
