Approximately 6 nH/cm for the total length of capacitor
winding and the leads.
The capacitors can withstand an unlimited number of pulses
with a dU/dt according to the article table. For peak to peak

PACKING
The box dimensions for bulk packaging are
245 x 145 x 80 mm. Quantity/package as
in article table, based on standard lead
length. Reels with taped capacitors are
packed 10 in a box with the dimensions
370 x 370 x 560 mm. Quantity per reel as
in article table. The standard quantity/reel
is for 360 mm reel. If 500 mm reel is
required, it must be specified when
ordering and the quantity is 2 x the given
quantity.
