Type SNU
Snubber Capacitors
Oil-Filled, Metallic Case for Snubber Applications
With a robust film/paper/extended foil construction,
Type SNU capacitors have low inductance and high
peak current ratings that make them ideal for power
snubber applications. The Type SNU may be used to
reduce voltage transients across semiconductor devices
such as SCRs.
