Murata Manufacturing Co., Ltd.: World’s Smallest Ferrite Beads / Noise Filter – 5 G Communications · IoT Equipment
~ Compact and high performance IoT and wearable equipment –
Background of development
Noise filter: required for power supply circuit and signal circuit of electronic equipment
Approximately 100 pieces are used for smartphones with miniaturization and higher performance
Further reduction in size is required for space reduction
In IoT equipment, which is expected to expand next generation communication (5G), circuits are incorporated in various small devices.
In other words, it is expected that the need for ultra compact noise filters will increase.
Due to miniaturization of internal coils and laminated parts, this product realized miniaturization of about 50% compared with the conventional base area.
