Murata has recently commercialized specialized type Ferrite Beads for EMI filtering. The BLF series is designed for suppressing specific unwanted noise for LTE band, Wi-Fi, and 5G Sub6. The BLE series has greatly improved DC saturation characteristics, when compared to the standard BLM-P series. This improved feature maintains its filtering performance even when high levels of current flow through the product. The last is the NFZ series. This EMI filter is designed to minimize any sound distortion when used on the audio signal line while still suppressing high frequency noise.
