Low ESR at a high frequency range. High ripple current capability. <Applications> Switching Power Supply and DC/DC Converter. Back up Power Supplies of CPU(VRM etc.) Miniature high Power Supply. <Environmental Correspondence> Compliant to the RoHS directive (2011/65/EU). The Lead-free of terminal plating. ■ Specifications Item Performance Characteristics Category Temperature Range –55 to +105°C Rated Voltage Range 2.0 to 25V Rated Capacitance Range 47 to 470µF Capacitance Tolerance ±20% at 120Hz, 20°C Tangent of loss angle (tan δ) Less than or equal to the specified value at 120Hz, 20°C ESR ( 1) Less than or equal to the specified value at 100kHz, 20°C Leakage Current ( 2) Less than or equal to the specified value. Endurance After 2 minutes' application of rated voltage at 20°C Test condition 105°C, rated voltage 1000Hrs. Capacitance change Within ±20% of initial value before test tan δ 150% or less than the initial specified value Leakage current ( 2) Less than or equal to the initial specified value Test condition 60°C, 90 to 95%RH, No Bias, 500Hrs. Damp Heat (Steady State) Capacitance change Within +50% to -20% of initial value before test tan δ 200% or less than the initial specified value Leakage current ( 2) 300% or less than the initial specified value Failure Rate 0.5% / 1000Hrs. Max. (60%CL) 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 105°C. ■ Recommended land Size ■ Size Code(ESR) Cap [µF] rie s Y a 7.3 × 4.3 × 4.3 2.9 2.05 4.1 WA 2.0 6.3 16 25 2.3 7.2 18.4 28.7 WA WA WA E (60) E (60) WB 47 E (55) E (55) 68 100 E (15) E (15) 220 330 470 X L [Upper value : Size Code, Lower value : ESR(mΩ)] R.V.(V) S.V.( V) se (mm) L×W×H E (9) E (6) H Z Z (mm) Size Code L±0.2 E 7.3 W1±0.2 W2 ±0.1 H ±0.2 Z±0.2 4.3 2.4 4.3 1.3 CONDUCTIVE POLYMER ALUMINUM SOLID ELECTROLYTIC CAPACITORS WA / WB series Standard Ratings Rated Voltage Surge Voltage (V) (V) (code) 2.0 (0D) 2.3 6.3 (0J) 7.2 16 (1C) 18.4 25 (1E) 28.7 Rated Capacitance (µF) Case Size L×W×H (mm) tan δ Leakage Current (µA, 2min.)
