Elimination of costly external suppression assemblies
The Amphenol ® MOV Connector offers the versatility of a
stan­dard connector, with transient protection for sensitive
circuits. Transients in electrical circuits caused by a sudden
release of stored energy can originate within or outside of
the circuit and may be repeatable or random.
Regardless of frequency or origin, transient caused failures
generated by load switching, lightning, electrostatic
discharge (ESD) and electromagnetic pulse (EMP) can
destroy unpro­tected IC components.
MOV
Compatible with present filter connector assembly
procedures, MOVs can be combined with existing filters.
Internal housing of the MOV offers weight and space savings
over other pro­tection methods available today, and
eliminates costly and bulky exterior suppression
mechanisms in appropriate situations. MOVs are presently
available in contact sizes 22, 20 and 16.
Transient protection can be provided in receptacle, plug or
adapter configuration. These connectors are intermateable
and intermountable with the following MIL-Specs:
•MIL-DTL-38999
•MIL-DTL-83723
•MIL-DTL-5015
•MIL-DTL-26482
•MIL-DTL-26500

output voltage of a typical MOV with 1000V, 5
nanosecond, 2.5A input pulse mounted in an
LJT 13–35P connector. Test was performed
without load.
