Eaton recently launched its automotive-grade HCM1AV2 product line of high-current power inductors designed for the transportation market to address increased power conversion and filtering requirements.
The robust molded construction makes the HCM1AV2 suitable for high vibration and shock conditions, says Eaton. The HCM1AV2 offers 10 standard inductor sizes and printed-circuit-board (PCB) footprints from 4 to 22 mm, high current capability up to 100 A, low dc resistance (DCR), low electromagnetic interference (EMI), high-voltage isolation, lower core loss, soft saturation (roll-off), and good performance stability across its operating temperature range.
According to the company, the advanced construction and high-grade materials used in HCM1AV2 inductors are designed to withstand the effects of high-temperature, high-humidity environments in many automotive electronic systems. The power inductors feature high-current carrying capacity, high power density, low core losses, and magnetic shielding to reduce EMI effects on other devices in the automotive engine compartment.
"As the electronics content in vehicles continues to increase, so does the challenge to provide reliable power management with less space, more weight restrictions, and performance stability under extreme ambient conditions," says Steve Subiry, global product manager, Eaton. "The HCM1AV2 meets the stringent requirements of the automotive industry, enduring a wide temperature range, high humidity, EMI, and increased mechanical shock and vibrations, providing enhanced reliability."
The HCM1AV2 inductors are AEC-Q200 Automotive Grade 1 compliant, with a maximum operating temperature range of -55 to +155°C (ambient plus self-temperature rise) in which a component can be safely operated. The inductors are also tested beyond AEC-Q200 Grade 1 requirements for added reliability and confidence desired by most automotive engineers.
