V05E11P Datasheet, PDF (2/2 Pages) Littelfuse – Superior Peak Surge Current Ratings in Small Disc Sizes

LV UltraMOV^™ Series Varistor
LV UltraMOV provides 4X greater surge protection
for low DC voltage applications in the smallest package
Epoxy Coated
Phenolic Coated
Features
• Breakthrough in low voltage
varistor design provides 4X
greater surge protection
• Reduced footprint and volume
required for surge protection
• High energy absorption capability
• High resistance to temperature cycling
• Optional phenolic coating
• Lead-free, halogen-free, and
RoHS compliant
Benefits
• Increased long-term reliability due to the ability to
handle higher surges over the end product’s lifetime
• More board space is available for higher value
functional components
• Lower weight and cost for end product from use
of a smaller disc
• Higher surge handling density in critical surge
protection device module solutions
• Higher operating temperature range—up to 125ºC
• Environmentally friendly product
How does LV UltraMOV
reduce varistor disc size?
The LV UltraMOV delivers
the same peak surge rating
in a disc that’s half the size
of other technologies on
the market.

Higher surge rating for the same size disc
LV UltraMOV improves the
reliability of the varistor by
enhancing the surge with-
standing capability of the
varistor device. For example,
a 5mm LV UltraMOV varistor
can withstand 100 times as
many 100A 8x20μs surges
as other 5mm varistors
currently available.

LV UltraMOV reduces counts for design engineers
LV UltraMOV can help circuit designers reduce counts based
on the total surge level, thereby reducing the footprint and
volume required for surge protection.
