The Encapsulated MOV Series is ideal for SMT 
processing and Pick and Place assembly.  Its low 
profile package offers space savings compared to 
leaded devices.  These encapsulated components 
can withstand higher surge energies (up to 1200A) 
than MLVs.  They are available in standard EIA sizes 
of 2825 and 4032 packages.  The construction is 
RoHS compliant and the coating is UL94-V0 rated. 
They are available with maximum continuous 
operating voltages (MCOV) ranging from 11VAC to 
680VAC. 
 

STYLE DESIGNATION 

The Maida Style Number is the typical means to 
identify our components when ordered. The style 
number identifies several parameters that are 
important for the characteristics of the device. An 
alternative ordering method, if known, is by our Item 
Number. 
The following example is the standard part 
numbering system when ordering our Encapsulated 
MOV Series components by the Maida Style Number:
