LA series varistors for Hi-Temperature operating conditions:
• Phenolic Coated LA Series devices are available with improved maxi-
mum operating maximum temperature 125°C.
• These devices also have improved temperature cycling performance
capability.
• To order this crimped and trimmed lead style, standard radial type
model numbers are changed by replacing the model letter “A” with “C”.
• Ratings and Specifications are as per standard LA Series except Hi-Pot
encapsulation Isolation Voltage Capability = 500V.
• To order: add X1347 to part number (e.g. V230LA20AX1347)
• Marked identifier will contain 'P' to denote Phenolic.
• These devices are not UL, CSA, VDE or CECC certified.
• Contact factory for further details.
Example:
For crimped leads without trimming and any variations to the above,
contact Littelfuse.
Ordering Information
LA series Varistors are shipped standard in bulk pack with straight leads
and lead spacing outlined in the package dimensions on page 4-13.
Contact your Littelfuse sales representative to discuss the non-standard
options outlined below.
• For 10/±1mm lead spacing on 20mm diameter models only; append
standard model numbers by adding “X10”.
Example:
For Lead-free and RoHS compliant parts add the letter ‘P’ after the base
part number and before any option as shown in the ordering example
below.
