Series 875, 877 Pigtail Fuses

First Real 3.6mm x 10mm Single Pigtail Fuse on the Market!

Littelfuse Buy Littelfuse Series 875 and 877 Pigtail Fuses Littelfuse Series 875 and 877 are the first real 3.6mm x 10mm fuses on the market. The more compact footprint was made possible by doing away with conventional over-capping (single pigtail) while achieving higher I 2 T values for the majority ampere ratings relative to the existing offerings in the market. These axial lead, Slo - Blo ®, Pigtail Fuses are ideal for electronic circuit designers who would like to optimize PCB board space and for electronic manufacturing purchasing agents and existing customers who are looking for alternative circuit protection solutions. Applications for the space saving fuses are lighting, power supply, and adapter applications.
