329
X329
ASC™ 329/X329 (IGBT Snubber Capacitors) are designed for
high demand environments as well as lower current
applications.
The 329 is a hybrid design combining self healing metallized
film and foil to maintain very high peak and RMS currents.
The X329 design utilizes only metallized film for applications
that require more moderate peak currents and RMS currents
but higher capacitance values.
Our new standard terminal style (W) meets the latest IGBT
products with respect to terminal spacing. Custom voltage,
capacitance values and terminal designs are available.
* Capacitance ratings are dependent upon voltage levels and total current
** Terminal to case test is only completed on a validation basis as the case is composed of nonconductive materials
