series S.V.(V) CONDUCTIVE POLYMER ALUMINUM SOLID ELECTROLYTIC CAPACITORS series WA/WB Resin-molded Chip (7.3 4.3 4.3) By using Functional Polymer cathode, Frequency & Temp. characteristics are greatly improved. Low ESR at a high frequency range. High ripple current capability. Applications Environmental Correspondence < > < > Switching Power Supply and DC/DC Converter. Compliant to the RoHS directive Back up Power Supplies of CPU(VRM etc.) (2011/65/EU). Miniature high Power Supply. The Lead-free of terminal plating. Item Performance Characteristics 55 to +105C 2.0 to 25V 47 to 470F 20% at 120Hz, 20C Tangent of loss angle (tan ) Less than or equal to the specified value at 120Hz, 20C ESR ( 1) Less than or equal to the specified value at 100kHz, 20C Leakage Current ( 2) Less than or equal to the specified value. After 2 minutes application of rated voltage at 20C Test condition 105C, rated voltage 1000Hrs. Capacitance change Within 20% of initial value before test Endurance tan 150% or less than the initial specified value Leakage current ( 2) Less than or equal to the initial specified value Test condition 60C, 90 to 95%RH, No Bias, 500Hrs. Capacitance change Within +50% to -20% of initial value before test Damp Heat (Steady State) tan 200% or less than the initial specified value Leakage current ( 2) 300% or less than the initial specified value 0.5% / 1000Hrs. Max. (60%CL) Failure Rate 1 ESR should be measured at both of the terminal ends closest to the capacitor body. 2 Conditioning : If any doubt arises, measure the leakage current after the voltage treatment of applying DC rated voltage continuously to the capacitor for 120 minutes at 105C.
