Product Type: Snubber

DMS Snubber Capacitor

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.



Shizuki began making capacitors in 1939 and ASC (Goodall Electric) in 1943. With a combined year total of 147 years of experience that ranged from low voltage DC (50) to high voltage AC (26,000). Shizuki was one of the pioneers in metallized film, and ASC (TRW) was a leader in the development of metallized polyester film capacitors.

Technology is at the forefront of Shizuki with three new R&D facilities focused on getting more out of what is available as well as new product development. Today’s product line up includes but not limited to Power Quality Systems, DC Link, AC Filter, Harmonic Filter, Home Appliance, Automotive, traditional through hole type capacitors and capacitors for Rail systems.  Factories are located in the United States, Japan and Thailand.
