signal protection
35.1 RJ11 Surge Protection Scheme
Advantages of the solution: Two-level protection is adopted, reliable operation, signal integrity is guaranteed, and the transmission frequency is 56KHZ .
Meet: IEC61000-4-2 , level 4 , contact discharge 8KV , air discharge 15KV ; IEC6100-4-5 10/700μs
6KV .
Tip: When the current is < 1A , the effect of using PPTC is better, and when the current is > 1A , use an inductance for decoupling.
