Steady State Power Derating UL RECOGNITION* The entire series including the bidirectional CA suffix has Underwriters Laboratory Recognition for the classification of protectors (QVGQ2) under the UL standard for safety 497B and File #E128662 . Many competitors only have one or two devices recognized or have recognition in a non-protective category. Some competitors have no recognition at all. With the UL497B recognition, our parts successfully passed several tests including Strike Voltage Specifications subject to change without notice. (c) 2016 Littelfuse, Inc. September 19, 2016 - Rev. 13 Breakdown test, Endurance Conditioning, Temperature test, Dielectric Voltage-Withstand test, Discharge test and several more. Whereas, some competitors have only passed a flammability test for the package material, we have been recognized for much more to be included in their protector category. *Applies to SA5.0A - SA170A. 4 Publication Order Number: SA5.0A/D SA5.0A Series PACKAGE DIMENSIONS AXIAL LEAD CASE 59AA-01 ISSUE A NOTES: 1.
