NOTE 2The capacitors may be used for any lower voltage rating. NOTE 3

22、Leakage current maximum permissible values are derived from the empirical term (0.003 CU + 4) 4A, where C is the rated capacitance of the capacitor, in 4F, and U is the rated voltage of the capacitor, in volts. The dimensions of C and U are not required in this derivation. NOTE 4The ripple currents

23、shown above are the maximum permissible values at a frequency of 100 Hz and temperature of 85 C. To obtain the ripple current rating at 50 Hz, the figure for 100 Hz is multiplied by 1/2. It should be noted that the life of a capacitor is extended by operating at lower ripple currents and low ambient

24、 temperatures. NOTE 5A capacitor may be mounted in any position, but preferably with the vent uppermost. The capacitors are not intended for mounting by their terminations only. NOTE 6Terminal screws supplied shall be of sufficient length to enable the requirements of the torque test (test Ud) to be

25、 satisfied when clamping a connection of thickness as detailed in the ordering information, clause 6.BS CECC30301024:1981 4 BSI 11-1999 5 Marking Items a) to e) shall be marked on the capacitor: a) rated capacitance in 4F; b) rated voltage and category temperature; c) polarity of the terminations; d
