Operating range(voltage, current, operating temperature) Use the capacitor within the specified imits listed below(a to b). Over rated conditions might cause deterioration damage, smoke and fire. Do not use capacitor beyond range of the condition a)Permissible voltage Rated voltage of this product is 250VDC. Use the capacitor within rated voltage When used in AC applied circuit, less than 125Vms. When used in a high frequency, less than 125Vrms should be applied and current applied should be less than the value of permissible current in Fig. 2-1, 2-2 in page 15 to 16. The performance of high temperature loading is in accordance with number 10, on page 4. The performance of moisture resistant loading is in accordance with number 9, on page 3. Not to be in connected directly to Primary or Ac line Use the peak of pulse voltage applied the capacitor within the dc rated voltage b) permissible current The permissible current must be considered by dividing into pulse current(peak current)and continuous curent(ms current). When using, therefore, make sure the both current are within the permissible values In the case that a continuous current value is able not to be measured use the capacitor within 75C as the inherent temperature rise confirmed by the measuring method show in page 14 Continuous current should be within specified figure in Fig. 2-1, 2-2. Contact us when the waveforms are totally different from the sine wave Pulse current should be within the figures calculated by Tab. 1. Use within 10000 cycles of pulse current When pulse current applied more than 10000 cycles, please consult us before use c)Operating temperature range It must be noted, however the operating temperature range is the surface temperature of the capacitor, not the ambient temperature of the capacitor. In actual use, make sure the sum of the ambient temperature own temperature rise value(Within specified value), that is the capacitor surface temperature is within the rated operating temperature range smoking or firing may be caused. Check the capacitor surface temperature at the heat source su and9 If there is cooling plate of the other part of any resistance heated to high temperature near the capacitor, the capacitor may be locally heated by the radiation heat, exceeding the operating temperature range d) Protective means for safety should be provided in case the pulse and rms current may exceed the permissible values due to abnomal action of elsewhere in the circuit Please cansult in advance when capacitors are connected in parallel to supplement capacitance Panasonic Electronic Devices Japan Co, Ltd.
