RJ-45 Ethernet surge protection

I have earlier written about Lightning protection and ADSL overvoltages and protection in this blog. And I have published several surge protection documents at ePanorama.net documents section. What about Ethernet line surge protection? Ethernet ports as they are are pretty well protected as they are compared to many other computer ports: Ethernet ports are transformer

Finding faults in coaxial cables

Coaxial cables are essential transmission lines in many RF/microwave applications. Coaxial cables are usually reliable, but sometimes coaxial cables can develop unseen faults that may be anywhere in their length. Finding those faults can often be challenging, typically requiring the use of time-domain reflectometry (TDR) which operates much like a radar system. Analysis of the reflected

SSR teardown

A solid state relay (SSR) is an industrial component used for interfacing low voltage control signals to high current mains voltage loads. The SSR may be designed to switch either AC or DC to the load. It serves the same function as an electromechanical relay, but has no moving parts. You can control SSRs easily

Perf+ prototyping board

Stripboard is the generic name (also known as Veroboard) for a widely used type of electronics prototyping board characterized by a 0.1 inch (2.54 mm) regular (rectangular) grid of holes, with wide parallel strips of copper cladding running in one direction all the way across one side of the board. Stripboard is available from many vendors. Stripboards
