I have searched here and the net, but there is hardly any detailed information.
What is the fundamental difference between a DC-Link MKP vs. an "ordinary" AC filtering MKP ?
For example, Roederstein MKP1848 vs MKP1840M.
Apart from small differences in loss factor, and a lower dV/dt, I cannot spot any major differences.
What is the underlying difference in the construction of the capacitor ?
Thanks in advance,
Patrick

AC/pulse caps have a thicker metallization, allowing them to withstand higher peak current without the risk of the metallization acting as a fuse
DC-Link application aims for lowest ESR and parasitic inductance as it usually sits on a specialised PCB bus trying to constrain switchmode current pulses to a defined loop path, and to minimise voltage disturbances to just that caused by the bulk capacitance on the bus. As such, they often provide terminal options.
