Title:
POWER FUSE AND FABRICATION METHODS WITH ENHANCED ARC MITIGATION AND THERMAL MANAGEMENT
Document Type and Number:
WIPO Patent Application WO/2016/133574
Kind Code:
A3
Abstract:
Power fuses having filler material including hydrated zeolite material (170) and quartz sand (172) facilitates increasing power density of electrical fuses in reduced package sizes. The hydrated zeolite material releases water to cool and suppress electrical arcing conditions experienced in higher power circuitry. The fuse element (158) is formed as a planar strip (160) with apertures (162) defining areas (162) of reduced cross-section which act as weak spots to faciliate arc division.
