Portable devices are also susceptible to electromagnetic interference (EMI), such as interference from strong sources of interference such as 2G/3G handsets, WLAN or Bluetooth. Therefore, it is necessary for portable devices to install EMI filters to suppress interference frequencies and achieve trouble-free operation. It should be noted that the interference frequency is not necessarily generated by the mobile device itself. If the mobile phone and other mobile devices are put together, the mobile phone will also generate interference frequency.
At present, NXP has introduced an ultra-thin leadless package, which is a solution that combines ESD protection and EMI filtering. The solution is highly integrated, simplifying cabling and making design easier. The high integration of the solution will greatly expand the application range of the product, not only reduce the board space, simplify the design, shorten the design cycle, but also reduce the hidden cost of the discrete solution in the production inspection, such as production line injection, feeding Check the cost.
The ESD protection solution for ambient temperature is tested against the IEC61000-4-2 standard. According to the IEC61000-4-2 standard, NXP's ESD protection solution has a maximum contact discharge protection voltage of up to 30kV, exceeding the highest level 4 protection voltage (8kV contact discharge) in the standard. The NXP solution also filters EMI emissions from 800MHz-3GHz handset frequencies with a maximum insertion loss of 30dB.
NXP's leadless package solutions use an industry-standard 0.4mmPin pitch and a thickness of no more than 0.5mm, which is in line with the trend toward lighter to thinner portable electronics. NXP offers 1/2/4/6/8 channel filters. All NXP solutions are based on the "DarkGreen" standard and are further halogen-free and flawless on the basis of RoHS compliance.

First, what is the classification of industrial routers?
Industrial Router (a communication device that can be divided into 2G routers, 2.5G routers, 3G routers and 4G routers according to network standards.
For users, you can communicate with the Internet by setting a default gateway on your PC or network device. In fact, the default gateway configured for network devices is the packet export for network devices. After the packet is sent to the Ethernet port of the router, the router performs the next job, so the router is an Internet relay.
Second, how do industrial routers work
So how does the router forward the packet? Just like getting somewhere, you need to place a route. This route is a routing table. This routing table contains all the destination network addresses owned by the router, as well as the best path to reach those networks through the router. This is because there is a routing table, so the router can forward packets according to the routing table. That's how routers work.
Understand what is an industrial router and how it works, it is not difficult to understand the advantages and disadvantages of the router. Here we focus on the advantages and disadvantages of 4G industrial routers.
Third, the advantages of 4G industrial routers
For networks interconnected via single-protocol industrial-grade wireless routers, the same or different protocols can be used at layers 1-2. Layer 3 uses the same routable protocol and requires the same or compatible protocols at layer 4 and beyond.
Industrial routers can perform complex routing calculations and are suitable for connecting three or more large networks with complex network topologies.
Industrial-grade routers can isolate broadcast storm information in the source network, thereby reducing and mitigating the impact of broadcast storms.
Multiprotocol industrial wireless routers can be used as network interconnection platforms using different communication protocols because they can connect to the network using different communication protocols.
The entire network router can also be used as a bridge to handle non-routable protocols.
Industrial 4G routers enable you to isolate unnecessary communications so that the interconnected network maintains its own area of independent management and control, thereby improving network security performance. Therefore, industrial-grade 4G routers are commonly used as firewalls to restrict access to the internal and external networks (Internet) of the LAN, as well as the internal areas of the LAN, and act as network masking.
It can provide reliable transport and prioritization services, and industrial LTE routers do not need to maintain a persistent connection between networks that communicate with each other.
Complete Netcom router network segmentation improves network performance and reduces host load.
Third, the advantages of 4G industrial routers
High price
When installing an industrial LTE router, it is difficult to install and maintain due to the large number of initial configurations
If you spend more time processing, the transmission performance of the entire network of the industrial router will decrease.
Unlike Bridges, routers across industrial networks are protocol-related. Each advanced protocol used for network connectivity must be configured separately, and an industrial-grade network-grade router with a separate protocol for each protocol must be provided.
Industrial Netcom routers do not support non-routed protocols, so when interconnecting multiple networks, there are restrictions on the protocols used by the connected networks.

Portable devices can be used in a variety of environments, so products need to be rugged. Electrostatic discharge (ESD) refers to the situation in which stored static electricity is released to surrounding electronic equipment through invisible lines. Electrostatic discharge can occur at any time when the device is touched, and is exposed to dry air such as cold air or in an air-conditioned environment.
