Abstract: A low inductance capacitor with annular distributed cores is provided, which relates to the technical field of capacitors, and includes a lower bus bar, capacitor cores and an upper bus bar. Currents accessed from lower connection terminals flow to a closed end of the lower bus bar along copper bar connecting plates, and flow to the upper bus bar through the capacitor cores, and then flow out from upper connection terminals to form a loop. And positions of the copper bar connecting plates are in one-to-one correspondence with positions of the capacitor cores, and flow directions of the currents are opposite.
