Murata - Filters guarantee reduced noise specification for Wi-Fi applications

Murata Manufacturing has released the BLF03VK series of ultra-compact noise filters, which are specifically created for the 5GHz band, which is one of the frequency ranges used for Wi-Fi (Wireless LAN) communications. This filter is called the first filter in the world with a specified and guaranteed impedance value at 5GHz. The company's new series of noise filters can suppress noise in the 5GHz band, which can block Wi-Fi signals, thereby enhancing data processing capabilities and speeding up data transmission. For companies that design Wi-Fi-enabled wireless communication equipment and companies that provide 5G equipment (such as base stations, Wi-Fi modules, smartphones, tablets, etc.), this product series includes two models: BLF03VK221SNG, the specified impedance is When 220Ohms is at 5GHz and rated current is 0.8A, BLV03VK600SNL is at 5GHz and 60Ω at 1.2A rated current. The impedance frequency characteristics of the device are controlled to minimize noise in the 5GHz band, emphasize low DC resistance and save space, and the compact size is 0.6mm x 0.3mm. This series of noise filters supporting the 5GHz band also improves the communication sensitivity of smartphones and other devices in Wi-Fi environments.
