There shall be no evidence of dye penetration. 16. Reduced Pressure Test: 16.1 Capacitors shall be stabilized at a reduced pressure of 0.315" (8.0) of mercury, equivalent to an altitude of 100 000 feet (30.480 m), for a period of 5 min. 16.2 Rated DC voltage shall be applied for 1 min. 16.3 Capacitors shall not flash over nor shall end seals be damaged. 16.4 Following the reduced pressure test, the capacitance, equivalent series resistance and leakage current shall meet the original requirements. 17. Lead Pull Test: Leads shall withstand a tensile stress of 3 pounds (1.4 kg) applied in any direction for 30 s. 18. Marking: Capacitors shall be marked with Sprague or (2); the type number 550D; rated capacitance and tolerance, rated DC working voltage and the standard EIA date code. 18.1 Capacitors shall be marked on one end with a plus sign (+) to identify the positive terminal. 18.2 Vishay Sprague reserves the right to furnish capacitors of higher working voltages than those ordered, where the physical size of the higher voltage units is identical to that of the units ordered. 2. V rms = I rms × Z where, P= Power Dissipation in W at + 25 °C as given in the table in Paragraph Number 5 (Power Dissipation). The capacitor Equivalent Series RESR = Resistance at the specified frequency. Z= The capacitor Impedance at the specified frequency. 2.1 The sum of the peak AC voltage plus the DC voltage shall not exceed the DC voltage rating of the capacitor. 2.2 The sum of the negative peak AC voltage plus the applied DC voltage shall not allow a voltage reversal exceeding 15 % of the DC working voltage at + 25 °C. 3. Reverse Voltage: These capacitors are capable of withstanding peak voltages in the reverse direction equal to 15 % of the DC rating at + 25 °C, 10 % of the DC rating at + 55 °C; 5 % of the DC rating at + 85 °C. 4. Temperature Derating: If these capacitors are to be operated at temperatures above + 25 °C, the permissible rms ripple current or voltage shall be calculated using the derating factors as shown: GUIDE TO APPLICATION 1. A-C Ripple Current: The maximum allowable ripple current shall be determined from the formula: I rms = P ---------------R ESR where, P= Power Dissipation in W at + 25 °C as given in the table in Paragraph Number 5 (Power Dissipation) A-C Ripple Voltage: The maximum allowable ripple voltage shall be determined from the formula: P V rms = Z ---------------R ESR or, from the formula: 5. Temperature Derating Factor + 25 °C 1.0 + 55 °C 0.8 + 85 °C 0.6 + 125 °C 0.4 Power Dissipation: The figures shown relate to an approximate + 20 °C rise in case temperature measured in free air. Power dissipation will be affected by the heat sinking capability of the mounting surface. Non-sinusoidal ripple current may produce heating effects which differ from those shown. It is important that the equivalent Irms value be established when calculating permissable operating levels.
