B32921C/D ... B32928C/D X2 / 305 V AC Pulse handling capability "dV/dt" represents the maximum permissible voltage change per unit of time for non-sinusoidal voltages, expressed in V/µs. "k0" represents the maximum permissible pulse characteristic of the waveform applied to the capacitor, expressed in V2/µs. Note: The values of dV/dt and k0 provided below must not be exceeded in order to avoid damaging the capacitor.
B32921C/D ... B32928C/D X2 / 305 V AC Mounting guidelines 1 Soldering 1.1 Solderability of leads The solderability of terminal leads is tested to IEC 60068-2-20, test Ta, method 1. Before a solderability test is carried out, terminals are subjected to accelerated ageing (to IEC 60068-2-2, test Ba: 4 h exposure to dry heat at 155 °C).

B32921C/D ... B32928C/D X2 / 305 V AC 1.3 General notes on soldering Permissible heat exposure loads on film capacitors are primarily characterized by the upper category temperature Tmax. Long exposure to temperatures above this type-related temperature limit can lead to changes in the plastic dielectric and thus change irreversibly a capacitor's electrical characteristics.
B32921C/D ... B32928C/D X2 / 305 V AC Application note for the different possible X1 / X2 positions In series with the powerline (i.e. capacitive power supply) In parallel with the powerline Typical Applications: Standard X2 are used parallel over the mains for reducing electromagnetic interferences coming from the grid. For such purposes they must meet the applicable EMC directives and standards.
B32921C/D ... B32928C/D X2 / 305 V AC Cautions and warnings Do not exceed the upper category temperature (UCT). Do not apply any mechanical stress to the capacitor terminals. Avoid any compressive, tensile or flexural stress. Do not move the capacitor after it has been soldered to the PC board. Do not pick up the PC board by the soldered capacitor. Do not place the capacitor on a PC board whose PTH hole spacing differs from the specified lead spacing.

Cleaning Use only suitable solvents for cleaning capacitors. Embedding of When embedding finished circuit assemblies in capacitors in plastic resins, chemical and thermal influences finished assemblies must be taken into account.
