SFI has developed the SHV series of multi-functional overvoltage protectors dedicated to LED lighting. SHV provides "Small Size SMD Chip" packaging, which is currently the world's smallest SMD package with high collapse voltage and high flow capacity, high nonlinear curve, high temperature and humidity resistance, low inhibition and anti-aging Excellent performance, can withstand multiple surge current impacts, and subvert traditional plug-in packaging, SMD products improve production yield, shorten working hours and solve space height restrictions, size covers 0603 to 3220, passed UL and TUV certification and have been used by multiple LED manufacturers both domestically and internationally.
1.SMD package (0806~3220).
2.Specially designed for LED lighting (DOB).
3.Smallest size with high collapse voltage and high flow capacity.
4.High non-linear index α Reaching (above 25).
5.The response speed is faster than the plug-in MOV (<1ns).
6.Passed IEC61000-4-5 testing.
7.Passed IEC61000-4-12 testing.
