8 / 11 page www.vishay.com 81 592D Vishay Sprague Document Number 40004 Revision 20-Oct-04 For technical questions, contact tantalum@vishay.com RESR = The capacitor Equivalent Series Resistance at the specified frequency. 3. A-C Ripple Voltage: The maximum allowable ripple voltage shall be determined from the formula: or, from the formula: where, P = Power Dissipation in Watts @ + 25°C as given in the table in Paragraph Number 6.0 (Power Dissipation). RESR = The capacitor Equivalent Series Resistance at the specified frequency. Z = The capacitor impedance at the specified frequency. 7.1 At + 25 °C, the leakage current shall not exceed the value listed in the Standard Ratings Table. 7.2 At + 85 °C, the leakage current shall not exceed 10 times the value listed in the Standard Ratings Table. 7.3 At + 125 °C, the leakage current shall not exceed 12 times the value listed in the Standard Ratings Table. 8. Equivalent Series Resistance: Measurements shall be made by the bridge method at, or referred to, a frequency of 100 KHz and a temperature of + 25°C. 8.1 The Equivalent Series Resistance shall not exceed the value listed in the Standard Ratings Table. 9. Life Test: Capacitors shall withstand rated DC voltage applied at + 85°C for 2000 hours or derated DC voltage applied at + 125°C for 1000 hours. 9.1 Following the life test, the dissipation factor and leakage shall meet the initial requirement; the capacitance change shall not exceed ± 10% of the initial value. 10 Humidity Test: Capacitors shall withstand 1000 hours at + 40°C, 90% to 95% relative humidity, with no voltage applied 10.1 Following the humidity test, capacitance change shall not exceed ± 10% of the initial value, dissipation factor shall not exceed 150% of the initial requirement; leakage currrent shall not exceed 200% of the initial requirement at + 25°C 11. Solderability: Capacitors will meet the solderability requirements of ANSI/J-STD-002, test B category 1. PERFORMANCE CHARACTERISTICS (Continued) 12. Resistance to Soldering Heat: Capacitors mounted on a substrate will withstand + 260°C for 5 seconds. 12.1 Following the resistance to soldering heat test, capacitance, dissipation factor and DC leakage current shall meet the initial requirement. 13. Marking: The small body area of these capacitors does not allow elaborate marking schemes. All required information is present on the carton or package in which the parts are shipped; in addition, part number, quantity and data code are indicated on the reels. 14. Terminal Strength: Per IEC-384-3, minimum of 5N shear force. 15. Environmental: Mercury, CFC and ODS materials are not used in the manufacture of these capacitors. 16. Flammability: Encapsulant materials meet UL94 V0 17. Capacitor Failure Mode: The predominant failure mode for solid tantalum capacitors is increased leakage current resulting in a shorted circuit. Capaci- tor failure may result from excess forward or reverse DC voltage, surge current, ripple current, thermal shock or excessive temperature. The increase in leakage is caused by a breakdown of the Ta 2O5 dielectric. For additional information on leakage failure of solid tantalum chip capacitors, refer to Vishay Sprague Technical Paper, “Leakage Failure Mode in Solid Tantalum Chip Capacitors.” Application Voltage Recommended (V) Capacitor Voltage Rating (V) 2.5 4 4 6.3 58 610 10 16 12 20 18 25 24 35 P RESR Irms = Vrms = Irms x Z P RESR Vrms = Z GUIDE TO APPLICATION 1.0 Recommended rated working voltage guidelines: (-55°C to + 85°C) 2. A-C Ripple Current: The maximum allowable ripple current shall be determined from the formula: where, P = Power Dissipation in Watts @ + 25°C as given in the table in Paragraph Number 6.0 (Power Dissipation) |
