Murata introduces metal power inductors for automotive applications

Murata has announced that it is making available the DFE32CAH_R0 series of metal power inductors for high-temperature applications of up to 150 °C.

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. Covering a wide inductance value range, they are suitable for in-vehicle applications beyond infotainment systems to the powertrain and advanced driver assistance systems (ADAS).

The DFE32CAHR47MR0L has a 0.47 µH inductance value, with an RDC of 14mOhm (Max) and an Isat of 8.7 A (Max). For the DFE32CAHR68MR0L, the main values are 0.68 µH for inductance, 17mOhm (Max) for RDC and 7.0A (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 4.8A. 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 43mOhm, 67mOhm and 101mOhm and Isat values of 4.0 A, 3.3 A, and 2.8 A.

These products have been designed to support large currents by optimising the internal coil structure design and utilising original metal materials and are suitable for a diverse range of automotive applications that require support for temperatures up to 150°C and demand large current flows.
