Unlike conventional ferrite types, Panasonic's ETQP power inductors use a metal composite material that offers significant advantages in current carrying capacity, saturation behavior and thermal stability: while ferrite inductors saturate quickly at high currents, the magnetization of the ETQP power inductor remains linear and temperature-stable up to 170 °C. At the same time, the material design enables more compact designs and lower power losses, which not only improves the overall efficiency of DC / DC converters but also reduces costs at the PCB level. The inductors also impress under mechanical stress: thanks to their robust construction, they can withstand vibrations of up to 50 G, making them ideal for use in safety-critical vehicle environments.
The ETQP power inductor is pin-compatible with many competing products, which facilitates integration into existing designs and ensures multi-source capability. Panasonic is the global market leader in metal composite inductors for automotive applications. With production facilities in Japan, Singapore and Indonesia, the company ensures high delivery availability and business continuity. In addition, the components score highly with zero field failures and have already been qualified by numerous global OEMs.
