AEM Components introduces a new line of high-current, high-power density solid body fuses. The new CMF Series is available in both commercial and automotive grade versions, each with part numbers with ratings from 20A to 100A@125 VDC. All models in this series are offered in the same 2822 surface-mount package. This standardized footprint for all models is a great benefit in platform design. The CMF Series also boasts industry-leading volumetric efficiency (178 mm3) and safe power density (548 VA/mm3@100A).
The CMF Series offer the best-in-class DCR ratings (1.85 mOhms@20A and 0.41 mOhms@100A) which limits excessive overheating due to temperature rise; high interrupt ratings (1500A@60Vdc / 250A@125Vdc) and clearing time characteristics (250% < 60s) to support exceptional inrush withstand capability and a wide operating temperature (-55C to 125C).
“The two major concerns with high current SMD fuses are the diversity of package sizes and safe power density,” reports Dr. Liwu Wang, AEM Components’ Director of Business Development. “AEM’s new CMF Series commercial and automotive grade fuses address both of these issues with performance that sets a new standard.”
The CMF Series builds on AEM Components advanced manufacturing technology. The solid, robust structure of these fuses assures reliable operation in environments where temperature cycling and high mechanical vibration are present. The devices singular fuse link/terminal construction eliminates problems that occur with traditional ceramic tube interconnection techniques.
Sample quantities of the competitively-priced CMF Series are now available. Full production of the commercial grade series is scheduled for early 2019. Automotive grade versions are currently undergoing qualification testing to AEC-Q200 and production quantities are expected to be available in 3Q2019.
