The new power inductors will address the growing safety requirements in the automotive industry, such as advanced driver assistance systems (ADAS), steering control, and braking systems. They also target automotive powertrain applications, including motor generators, transmission system controllers, and electronic battery management control units.
Panasonic's new ETQP*M* series is half the size of conventional ferrite technology inductors and 15% to 30% smaller than iron-core magnetic technology inductors. Their compact size and sleek design facilitate integration to meet the current and power requirements of even the most demanding applications. Furthermore, a single inductor can often cover a wide range of power, current, and mechanical requirements that would normally require many different components. The high-performance ETQP*M* series can also help improve efficiency in manufacturing and industrial systems through easy integration into factory automation applications and collaborative robot (cobot) designs.
Two market-leading products from the ETQP*M* series are now available for fast delivery from Farnell: ETQ-P5M470YFK and ETQ-P4M3R3YFN.
These are some of its main features:
High heat resistance: Operating temperature from -40°C to 150°C (up to 180°C for short periods), including self-heating.
High reliability: As a result of the integral construction of each product, they offer high vibration resistance, designed to withstand the demanding reliability conditions of automotive and other strenuous applications
. High bias current: Excellent inductance stability using ferrous alloy magnetic material.
Temperature stability: A varied inductance range from 0.33 μH to 100 μH and excellent inductance stability.
Low audible noise (hum): The ETQP*M* series incorporates Panasonic Industry's new metal composite core technology, suitable for filters and step-down/step-up circuits for DC/DC converters.
High efficiency: The AEC-Q200 compliant and RoHS-compliant ETQP*M* series offers low winding DC resistance and low core eddy current losses.
Simon Meadmore, Vice President of Product and Supplier Management at Farnell, comments: “Automotive design is witnessing a near-dizzying pace in the transition to electrification. There is a clear trend toward more compact components that can save space, improve efficiency, and reduce the weight of critical applications. Consequently, the demand for passive components, such as choke coils, that can reliably withstand the harsh conditions of the automotive industry is greater than ever, and it’s not just about their robust construction and heat resistance. Panasonic’s new ETQP*M* series meets all these essential requirements for high-quality power inductors.”
