Murata BLF03VK series compact noise filters

Murata has released  the BLF03VK Series of compact (0.6 x 0.3mm) noise filters specifically designed for the 5GHz band, one of the frequency ranges used in Wi-Fi (wireless LAN) communications, for the first time in the world*.
* Based on an internal study as of July 2019

The 5GHz band for Wi-Fi is known as high-speed transportation band.  However, when a device itself generates noise in this frequency band, this interferes with the signals received, resulting in lower data processing performance and slower transmission. Murata's new BLF03VK series of noise filters suppress noise in the 5GHz band that interferes with W-Fi signals, thereby contributing to improved data processing capability and faster data transmission. These products are the first noise filters that provide a guaranteed impedance value at 5GHz band.  Murata has begun mass production of the series.
