Eaton has launched its automotive grade HCM1A product line of high current power inductors designed to meet electronic system power and thermal handling requirements of transportation manufacturers.

The alloy powder core material of the HCM1A inductors are designed to withstand stresses found in vehicle engine compartments and deliver reliability for DC-to-DC converters, voltage regulators, battery powered systems, multi-phase regulators and point of load modules.

“Vehicle engine compartments present environmental challenges and auto manufacturers want assurance the components they use are up to those demands,” said Eaton global product manager, Steve Subiry.

“The Automotive Electronics Council (AEC) Component Technical Committee specifies the Q200 standard to ensure electronic components used in vehicles are reliable and the HCM1A product line has been designed to comply with this standard.”

The supplier says materials used in the construction of HCM1A inductors are designed to withstand the effects of thermal ageing and protect against corrosion to provide dependable electronic systems.

HCM1A inductors are AEC-Q200 Automotive Grade 1 compliant, which specifies minus 40 degrees to 125 degrees Celsius as the minimum and maximum range of ambient temperatures in which a component can be safely operated.

The low core loss performance of the HCM1A product line is designed for input and output filtering applications used in engine compartments with more sophisticated digital control and direct current (DC) motors.

These motors generate noise in engine compartments which could adversely affect the performance of adjacent electronic systems. Filters with HCM1A conductors are designed to reduce this noise maintains the company.

The HCM1A product line offers surface mount packaging with a range of sizes and compact heights starting at 3mm.

 The line includes seven different part numbers to meet a variety of specifications and design requirements.
