High Voltage Ceramic Capacitor Applications where high dv/dt is present will operate at high peak currents (Ip = dv/dt x C). Capacitors should be evaluated in the actual circuit for dv/dt greater than 2000V/ microsecond. If repetitive, it may be necessary to use a series resistor or other impedance to limit peak currents to safe values. 75-136A 0.437 ±0.015 0.250 DIA 0.437 ±0.015 0.250 [email protected] 0.187 FLAT NO. 8-32 NC-2B THD 75-134A NO. 6-32 NC-2B THD www.vishay.com 30 715C Series TYPE KT CAPACITOR 40,000 VDC; 9,000 VRMS, 60HZ -30 22.4 26.7 33.0 39.4 45.7 54.1 58.4 61.5 LENGTH MAX. in. mm .780 19.8 .900 22.9 1.00 25.4 1.18 30.0 1.36 34.5 TYPE DK CAPACITOR 30,000 VDC; 7,000 VRMS, 60HZ 30 .880 1.05 1.30 1.55 1.80 2.13 2.30 2.42 L SIZE CODE J K L M N 0.250 DIA 0.312 0.187 FLAT NO. 6-32 NC-2B INT THD 0.187 FLAT Document Number: 23098 Revision 14-May-02
