High-current power inductors

4 November 2015 Passive Components

Eaton announced the launch of its automotive grade Coiltronics HCMA series of high-current power inductors to meet and exceed the AEC Q200 Grade 3 standard with a maximum total temperature operation range from -55°C to 125°C. The inductors are designed to withstand temperature 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 the above standard. Each inductor in the series is made of powder iron core material, and is magnetically shielded for low electromagnetic interference (EMI). The HCMA0503 has a frequency range up to 1 MHz while the HCMA0703, HCMA1104, HCMA1305 and HCMA1707 operate up to 5 MHz. Each component also features high current carrying capacity and low core losses.

The HCMA series is provided in surface mount packaging with a range of compact heights beginning at 3 mm and extending up to 7 mm. The series also covers a wide range of inductance values, starting from 0,10 H all the way up to 68,0 H. Current ranges for the series start at 1,8 A and extend up to 118 A.
