LA Varistor Series  
Description  
The LA Series of transient voltage surge suppressors are  
radial leaded varistors (MOVs) that are designed to be  
operated continuously across AC power lines. These UL  
recognized varistors require very little mounting space,  
and are offered in various standard lead form options.  
The LA Series varistors are available in four model  
sizes: 7mm, 10mm, 14mm and 20mm; and have a  
V
M(AC)RMS voltage range from 130V to 1000V, and an  
energy absorption capability up to 360J. Some LA Series  
model numbers are available with clamping voltage  
selections, designated by a model number suffix of  
either A or B. The 'A' selection is the standard model;  
the 'B' selection provides a lower clamping voltage.  
See LA Series Device Ratings and Specifications  
Table for part number and brand information.

at high temperatures as shown above. Because varistors  
only dissipate a relatively small amount of average power  
they are not suitable for repetitive applications that involve  
substantial amounts of average power dissipation.  
Should transients occur in rapid succession, the average
