application background
1 Global warming, more thunders↕₹βtorms.
2 Network equipment ∑← is easily damaged by lightning, wh→™ich is extremely harmfu™↑∏l.
3 The maintenance cost of↓ network equipment after b×αeing damaged by lightn•'ing is high
4 Network equipment wδ€♥₽ith high surge protectioββn capability has become an ↓∑ industry trend
Program description and precaution✔δ"÷s
1 In this solution, G✔∞DT is used for common-mode (eight-wir<e) surge protection at the front ≥€×end of the transformer €.
2 The low-junction capacitance ★ε↕TVS removes the differential mo×λde energy at the back end of th ☆<e transformer, while TVS iα≥s used for electrostatic protecti≥±on, and the response time i><s fast
3 Complies with 802.11 electrical st←∑andards.
4 Satisfy IEC61000-4-5♣ $, GBT17626.5 and other surge te¥₩st standards.
5 Meet static test standards such ×↕≤as IEC61000-4-2 and GBT17626.2.
