Automotive Grade Coiltronics HCMA Series High Current Power Inductors

Automotive Grade Coiltronics HCMA Series High Current Power Inductors

Power management company Eaton an-nounced the launch of its automotive grade Coiltronics® HCMA Series of high current power inductors to meet and exceed the Automotive Electronics Council’s (AEC) Q200 Grade 3 standard with a maximum total temperature operation range from minus 55 degrees to 125 degrees Celsius (C). The inductors are designed to withstand tempera-ture and shock stresses found in automotive applications to support greater reliability in electronics for Advanced Drive Assistance Systems (ADAS), vehicle control, body control, lighting, infotainment, cluster controls, heating and air conditioning, chassis and safety systems. 

Eaton designed, manufactured and tested the entire inductor series that includes HCMA0503, HCMA0703, HCMA1104, HCMA1305, and HCMA1707 to ensure compliance with AEC-Q200 Grade 3 standard. The AEC Component Technical Committee’s definition of common electrical qualifications in automotive environments requires induc-tors to operatereliably in temperatures ranging from minus 40 degrees to 85 degrees (C). AEC-Q200 testing stresses devices beyond typical commercial reliability tests for temperature cycling duration and thermal shock. This reliability is required for DC-to-DC converters, voltage regulation modules, battery powered systems, multi-phase regulators and point-of-load modules used in vehicle electronic systems.
