Power inductors provide protection for automotive applications
Additions to the DFE series of power inductors developed specifically for use within in-vehicle applications such as advanced driver assistance systems (ADAS), automotive infotainment systems and power-train components, have been announced by Murata. Offering the industry’s highest levels of electrostatic discharge (ESD) surge voltage protection, the compact AEC-Q200 compliant devices provide high insulation and ESD characteristics.
The DFE2HCAH series measures 2.5x2.0x1.2mm and provides 1kV protection, and the DFE2MCAH series measures 2.0x1.6x1.2mm and is rated at 500V ESD protection. Both series are fabricated using Murata’s metal alloy material and accommodate the automotive operating temperature range from -40 to +150°C.
In addition to the high ESD protection features the compact dimensions of the new power inductors ensure the minimum of PCB space is required, aiding designers to accommodate today’s space-constrained applications. Inductance values available are in the range of 0.33 to 2.2µH with a value-dependent maximum current rating of 5.8A.
