Metal power inductors for in-vehicle applications
Metal power inductors for in-vehicle applications offer major improvements in Isat and RDC specifications
New DFE32CAH_R0 series of metal power inductors for high-temperature applications of up to 150°C from supplier Murata. Intended for use in DC/DC converters and power management circuitry for automotive applications, these components are supplied in 1210 inch size (3.2 mm × 2.5 mm) metal cores. These new products support large currents by optimizing the internal coil structure design and utilizing original metal materials.
Covering a wide inductance value range, the components are suitable for in-vehicle applications beyond infotainment systems to the powertrain and advanced driver assistance systems (ADAS).
Meeting demands for high currents and the downsizing of system designs, the DFE32CAH_R0 delivers a DC superimposed current rating (Isat) of 8.7 A in the world’s best for a 1210 inch size product with an inductance of 0.47 µH.
The DFE32CAHR47MR0L has a 0.47 µH inductance value, with an RDC of 14 mOhm (Max) and an Isat of 8.7 A (Max).
For the DFE32CAHR68MR0L, the main values are 0.68 µH for inductance, 17 mOhm (Max) for RDC and 7.0 A (Max) for Isat.
The 1.0 µH-rated DFE32CAH1R0MR0L and 1.5 µH-rated DFE32CAH1R5MR0L have respective RDC values of 22 mOhm and 30 mOhm, with Isat figures of 5.9 A and 4.8 A.
The DFE32CAH-2R2/3R3/4R7-MR0L inductors have respective inductance ratings of 2.2 µH, 3.3 µH, and 4.7 µH with RDC figures 43 mOhm, 67 mOhm and 101 mOhm and Isat values of 4.0 A, 3.3 A, and 2.8 A.
