How to Connect a Littelfuse Varistor
Transient suppressors can be exposed to high currents for
short durations in the nanoseconds to millisecond time
frame.
Littelfuse Varistors are connected in parallel to the load, and
any voltage drop in the leads to the varistor will reduce its
effectiveness. Best results are obtained by using short
leads that are close together to reduce induced voltages
and a low ohmic resistance to reduce I • R drops.
