New ETQ-P4M100YFP Power Inductor for Automotive Applications

Panasonic, a worldwide leader in Inductor Products, announces the new ETQ-P4M100YFP Power Inductor, part of the High Performance Type -ETQP*M**Y** Series of Power Choke Coils.  This new Inductor provides exceptional large current support, high heat resistance, and high vibration resistance. At 5.0x5.5mm, this Surface Mount Power Inductor is part of the industry’s smallest class of SMT Inductors and meets the market demands for smaller automotive ECU’s (Electronic Control Unit) enabling them to be directly mounted on engines while achieving excellent heat and vibration resistance.

The compact and highly reliable surface mount ETQ-P4M100YFP improves the reliability of power circuits while contributing to the reduction of environmental impact by saving space in power circuit mounting areas. Panasonic’s ETQ-P4M100YFP Power Choke Coil offers large current support 3.0A, DC current which causes a temperature rise of 40K.  Parts are soldered by reflow on multilayer PWB with high heat dissipation performance.  

Note: Heat radiation constant is approx. 48K/W measured. The ETQ-P4M100YFP Power Inductor provides high heat resistance of 150°C/2000 hours and vibration resistance of 5 Hz to 2 kHz/10 G, making it compatible with mechatronics.
