With the improvement of the integration of electronic products, processor speed, switch rate and interface rate rising, the importance of technology in electronic systems has become increasingly prominent compatible ESD protection, lightning protection, surge protection and EMI/EMC protection circuit and electromagnetic overcurrent protection and overvoltage protection device selection and application of electromagnetic interference and electromagnetic radiation, conduction disturbance to eliminate the problem, EMC test environment and solving method have become the difficulties and challenges in the process of design engineer.

Circuit protection technology upgrades electronic component selection challenges
Circuit protection is the basic discipline of circuit design, is the most prone to problems, but also easy to be ignored. ESD protection, lightning protection design, over-current protection and other puzzles almost every circuit design engineer. In fact, in communications, consumer, military, aerospace and other fields, ESD is often caused by the culprit circuit failure. Recognizing the ESD, overvoltage, surge, overheating and other phenomena of great harm, the protection device manufacturers are constantly introducing new products to meet design needs. In addition to attention to volt ampere characteristics, protection levels and other factors, the latest circuit protection devices also need to consider more other issues. For example, electronic devices increasingly thin, in order to limit the size and in a smaller area for circuit protection, protection device manufacturers need to develop smaller components, which requires manufacturers to continuously improve the components of the energy density; at the same time, the interface rate continues to improve, in order to ensure signal integrity must be considered to protect the size of the capacitor device, the protection scheme must follow the trend of the development of the interface, ensure the stability of the interface; in addition, the impact resistant protection components and the number of the earthquake, also need to consider the characteristics of moisture.

Circuit protection components usually include overvoltage protection devices and over-current protection devices two. Overvoltage protection device TG from electronic R & D and production of TVS transient suppression diode, MOV varistor, MLV SMD varistors, GDT SPG glass ceramic gas discharge tube, gas discharge tube, TSS semiconductor solid discharge tube, ESD static diode; overcurrent protection devices including the PTC self recovery fuse. Engineers need to choose the characteristics of various components and different types of applications.

In order to meet the needs of engineers for circuit protection design, component selection, over flow voltage protection and EMC design and test technology. To provide free samples for electronic engineers test, welcome to consult!
