11、sList 17 Appendix 3 Terminals oil impregnated; extended foil electrode capacitors, hermetically sealed in metal cases, for general purpose application in power semiconductor circuits. These capacitors are intended for such uses as SCR commutating, snubbers, harmonic filters, EMI/RFI suppression, in

12、motor speed controls, static power supplies, frequency changers, and similar applications. 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 2.10 2. DEFINITIONS Effective Voltage is the voltage used to determine the effective volt-amperes. This voltage is the rms value calculated only during those portions of the

13、 total period that the voltage is changing. See Appendix 6, Page 23. 6O-Hz rms Voltage Reference is the nominal continuous 60-Hz sinewave voltage that may be applied between the capacitor terminals. This rating is primarily intended as a reference value for capacitor design and testing, but excludin

14、g temperature-rise testing. Peak Voltage Rating is the maximum voltage change (plus or minus) from zero reference applied between the capacitor terminals. Zero reference is the condition where there is no potential across the terminals of the capacitor. See Appendix 6, Page 23. Peak-Peak Voltage is

15、the maximum total change in voltage applied between the capacitor ter- minals during one repetitive cycle. See Appendix 6, Page 23. Rms Current is the root-mean-square or effective current and is the value used to determine the effective volt-amperes. See Appendix 6, Page 23. Peak Current is the max

16、imum amplitude of current which occurs repetitively in charging or discharging a capacitor. See Appendix 6, Page 23. Current Puise Width is the time of current flow in microseconds during the charge or discharge of capacitors. See Appendix 6, Page 23. Volt-Amperes is the product of the effective vol

17、tage and effective current applied to a capacitor. This value provides a means of calculating the watts loss and temperature rise of a capacitor. See Appendix 6, Page 23. Rise Time is the time in microseconds required to charge a.capacitor from 10% to 90% of the maximum change in voltage (A V) appli

18、ed between the capacitor terminals during one repetitive cycle. See Appendix 6, Page 24. Case Temperature Rating is the maximum allowable hot spot temperature developed at any point on the case surface. (See Paragraph 20.4.) EIA 401 73 m 3234600 0067775 9 m .
