SFI has developed the SHN series of multi-functional overvoltage protectors dedicated to the Netcom cloud. SHN itself has a large capacitance, which can provide better filtering effect for IEEE820.3af requirements. At the same time, SHN provides "ultra-small size SMD chip" packaging, and has "excellent high temperature characteristics" and "passed 10*700us test standard", Compared with the current "disadvantages" of "conduction freewheeling" and "poor packaging air leakage" when using GDT in the market, SHN is the best choice for overvoltage components applied in the network cloud.
1.SMD package (0806~1812).
2.Specially designed for lightning protection of network ports (RJ45).
3.Common mode test (L-G 1kV~8KV).
4.Extremely low leakage current (<10μA).
5.The response speed is faster than the plug-in MOV (<1ns).
6.High non-linear index α Reaching (above 25).
7.Passed IEC61000-4-5 (10*700us) testing.
8.Good impact ability exceeding 100 times.
9.Compliant with RoHS requirements and lead-free tin furnace.
10.Non polar bidirectional action.
11.Extremely wide operating temperature -55°C
to +125°C.
12.Avoid GDT freewheeling performance attenuation.
13.Space saving and competitive advantage.
1.Large size of plug-in packaging (5 Å~14 Å).
2.High suppression voltage.
3.Large leakage current (<50μA).
4.Slow reaction speed (>100ns).
5.Severe deterioration phenomenon.
6.Failure modes may lead to combustion phenomena.
1.The static and dynamic overload capacity is poor, and it is easy to be misconducted by interference.
2.Suppression voltage is lower than SHA.
3.Less resistant to continuous impact.
4.Fast reaction speed (<1ns).
5.SMD package is larger than SHN.
