On March 19th, Murata Manufacturing Co., Ltd. commercialized the sheet-like ferrite bead BLM21SP series for the 0805 size (2.0 x 1.25mm) power supply for automotive power transmission and safety applications. The product achieves a rated current of 6A, the industry's ultra-high impedance of 70ohm, is expected to have a higher noise suppression effect. The BLM21SP series is used on noise-prone power lines to contribute to the definition of noise standards such as CISPR25. The product will begin mass production in March 2018. In recent years, with the electrification of various functions such as hybrid vehicles and electric vehicles, more and more electronic devices have been mounted. The resulting conduction noise and radiation noise also increase, and the necessity of using noise suppression measures is increased. In particular, a power supply line through which a large current passes is prone to noise problems, and a countermeasure against noise is required. However, it is difficult to design a high-rated current and high-impedance noise suppression component for a power supply line. The company has improved the structural design by introducing a new internal electrode forming technology. Get the efficiency of the impedance. The company's existing power supply products BLM21PG series is 6A, 22Ω@100MHz, and with this technology, the same size achieves 6A, 2 times more than 70Ω@100MHz. In addition, the rated current is increased to 1.5 times or more in comparison with the same impedance value. Characteristics Support automotive power transmission, safety Meets AEC-Q200 standards Small (2.0 x 1.25mm), supporting up to 6A high current High current and high impedance product lineup (70ohm/6A, 110ohm/5A, 180ohm/4A) The name of wireless router can be separated out of two keywords: wireless and routing. Understand the technical principle behind these two words, you understand the wireless router.

Wireless is also what we often call Wi-Fi. Wireless routers can convert home broadband from wired to wireless signals, and all devices can happily surf the Internet as long as they connect to their own Wi-Fi. In addition, these devices also form a wireless local area network, where local data is exchanged at high speed and is not limited by the bandwidth of home broadband.
For example, many people have smart speakers in their homes that can be used to control various smart appliances. When you say small X small X, turn on the TV, the speaker actually finds the TV through the LAN and sends instructions, and does not need to connect to the Internet; And if you let it broadcast news, you have to get data through the Internet.
The Local Area Network we talked about earlier, also known as the Intranet, is represented by the Local Area Network (LAN) on the router, so the Wi-Fi signal is also called WLAN(Wireless LAN); The Internet we want to access, also known as the extranet, is represented on the router by the WAN(Wide Area Network).
On the Intranet, the IP address of each device is different, which is called a private address. All devices on the Internet share the same public address, which is assigned by broadband operators such as China Telecom Unicom.
The router is the bridge between the Intranet and the external network. The above mentioned IP address translation, packet forwarding, is the router routing function.
In other words, the router is the hub of the home network, and the data of all the devices must be forwarded through it to access each other or reach the external network, which means that one husband is the key and ten thousand men are not open, so the comprehensive router is also called "home gateway".
