Description
The LA Varistor 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 Varistor Series are available in four model sizes: 7mm, 10mm, 14mm and 20mm; and have a VM(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.
Features
• Lead–free, HalogenFree and RoHS compliant.
• Energy absorption capability (WTM) up to 360J
• Wide operating voltage range VM(AC)RMS 130V to 1000V
• No derating up to 85ºC ambient
• Available in tape and reel or bulk pack
