Murata has launched a series of power inductors specifically designed for automotive powertrain and safety equipment.

The DFE2MCPH_JL 40V automotive-grade metal alloy power inductor series has values of 0.33µH and 0.47µH in a 0806 surface mount package.

Compared with existing products in the Murata DFE2MCAH_J0 series, the 0.33µH part reduces the DC resistance by 38% to 18 mOhm along with a 31% increase in rated current to 5.1 A for the same temperature rise. The rated current for a specified inductance drop is also 64% higher at 6.9 A.

In addition, the power inductor has 40V of withstand voltage, and this is all in 0806-inch size with an operating temperature range of -40°C to +155°C with current derating.

The metal alloy inductors are aimed at demanding automotive applications such as ADAS and IVI systems.

The high DC current rating and low power dissipation of the DFE2MCPH_JL series, complemented by a high impulse voltage rating, make them particularly suitable for low-loss filtering and energy storage in power converter applications. At the same time, the miniature 0806 SMT package saves space and material usage.

Murata will continue to expand inductance value from 0.1 µH to 4.7µH in the future.

Further applications for these high current, high-grade inductors are in automotive infotainment/comfort systems and medical equipment GHTF Classes A, B and Class C (not implant).
