To order, add X1347 to end of part number (Example: V230LA20APX1347). For additional information please refer to the section labeled "Phenolic Coating Option" on the third page of this document under the "Electrical Characteristics" table. Crimped leads are standard on LA Series varistors supplied in tape and reel, denoted with "LT ." For crimped leads without trimming and any varitions other than that described above, please contact Littelfuse. For standard parts, use the BASE PART designator only. For parts with non-standard options (such as additional form, packaging and lead space options), use BASE PART + OPTION CODE. OPTION CODE items are subject to availability and minimum order requirements. Please contact a Littelfuse products representative for additional information or questions BASE PART CODES: OPTION CODES: Standard Model Order As V130LA20AP V130LA20AP X2855 X10: 10mm lead spacing option -- For 10 (-/+1) mm lead spacing (available on 20mm diameter models only), append standard model BASE PART number with "X10." Example: X2855: Nickel Barrier coated wire option -- All standard parts use Tin–coated Copper wire. Nickel Barrier coated wire is available as an option, consisting of Copper wire with a flashing of Nickel followed by a top coating of Tin. To order append standard model BASE PART number with "X2855." Example:Littelfuse LA Series varistors are shipped standard in bulk pack with straight leads and lead spacing outlined in the Package Dimensions section of this data sheet. Contact your Littelfuse sales representative to discuss non-standard options.
