Automotive-grade power inductors deliver the highest industry standards

Murata has expanded its line-up by releasing the DFE2MCPH_JL series of automotive-grade power inductors with values of 0.33µH and 0.47µH, specifically designed for automotive powertrain/safety equipment. Compared with existing products in the DFE2MCAH_J0 series, the 0.33µH part, for example, attains the highest standards in the industry with a reduction of 38% in DC resistance to 18mOhm along with a 31% increase in rated current to 5.1A for the same temperature rise. The rated current for a specified inductance drop is also 64% higher at 6.9A. In addition, this product realised 40V of withstand voltage, which is all in a 0806" size with an operating temperature range of -40C to +155C with current derating.

The metal alloy inductors leverage the company's material and manufacturing technology advances to attain high quality and performance. This makes the parts ideal for demanding automotive applications such as ADAS and IVI systems – a rapidly expanding market.

The series' high DC current rating and low power dissipation, complemented by a high impulse voltage rating, make it especially suited to low-loss filtering and energy storage in power converter applications. At the same time, the miniature package saves space and material usage.

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).
