Power inductors feature high heat and vibration resistance

Panasonic Industry Europe is launching new highly reliable power inductors for automotive and other strenuous applications requiring high heat (up to +150°C including self-heating) and vibration resistance (up to 30G).

Benefiting from a shielded construction, low profile (only 3mm maximum height), excellent inductance and temperature stability over a broad temperature range, as well as low audible (buzz) noise, the components are ideal to be designed into high frequency switching systems over 2MHz.

Patrick Weigand, Product Marketing Manager at Panasonic comments: “Using a metal composite core our ETQ-P3MxxxHFx series power choke coils are AEC-Q200 compliant ensuring optimal quality and reliability for use applications like noise filters for drive circuitries, DC to DC converters, buck converters, boost converters, and LED driver applications especially for high frequency switching systems.”

Key features:

  • Reduce core loss in high frequency band (More than 2 MHz)

  • High heat resistance : Operation up to 150 °C including self-heating

  • Low profile : 3 mm max. height

  • SMD type

  • High-reliability : High vibration resistance as result of newly developed integral construction; under severe reliability conditions of automotive and other strenuous applications

  • High bias current : Excellent inductance stability using ferrous alloy magnetic material

  • Temp. stability : Excellent inductance stability over broad temp. range

  • Low audible (buzz) noise : New metal composite core technology

  • High efficiency : Low RDC of winding and low eddy-current loss of the core

  • Shielded construction

  • AEC-Q200 Automotive qualified

  • RoHS compliant

CPU choice for display based systems
Behind every display based system is the CPU which acts as the brain of the entire module creating the data that is presented as well as driving the I/O peripherals, display and touchscreen. There are many factors to consider when choosing the right CPU for your project, including whether you pick a complete Single Board Computer (SBC) or a stripped back core module (COM).
