Standard circuit design for POE outdoor lightning protection solution

In today's world, where the vast majority of end-use electronic devices (for consumer electronics, transportation, communications, and industrial) are connected to each other through some form of communication network, the Ethernet protocol is used in many common applications we encounter every day. 1. Industry pain points: limitations of traditional network transformers In the fields of industrial automation, smart cars, and 5G devices, Ethernet transformers are the core components that ensure signal integrity. However, traditional toroidal transformers face three major challenges: 1. Manual

With the rapid development of smart manufacturing and the Industrial Internet of Things (IIoT), industrial communications are moving towards high-speed and intelligent technologies. Industrial automation equipment requires real-time, efficient transmission of large amounts of data to achieve precise control and collaborative operations. Industrial Ethernet fieldbus, with its high speed, high reliability, and strong compatibility, has become the mainstream choice for industrial communications and is widely used in smart manufacturing, smart factories, industrial automation, and other fields. T

In today's era of increasingly sophisticated and complex electronic devices, electromagnetic compatibility (EMC) has become a critical threshold for product reliability and market competitiveness. Both weak signals in high-speed transmission and the energy lifeline of stable power supply are constantly threatened by ubiquitous common mode noise. Such noise can, at best, cause data errors and audio-visual distortion; at worst, it may lead to system crashes or even endanger safety. As the "noise filter" of electronic systems, common mode chokes play an indispensable role. However, many engineer
