1. Summary

As the development of modern electronics, more and more people have applied SiC / GaN power component in different specific field. Engineers will always need to measure the power circuit with above hundreds kHz of frequency and tens ampere of current. The traditional high frequency current probe (such as our HCP8000 series) containing iron core and shielding layer will suffer large loss and heating under high frequency current (Please refer to the current frequency derating curve from the HCP8000 series instruction manual.) As a result,the  expensive probe will be broken.

Coaxial Shunt is pure resistor structure and can remain low loss even under high frequency current , making it a very good choice for your high frequency current testing. Our coaxial shunt is divided into two types based on connection method:

1. Wire type: CSD***A/B series coaxial shunt is soldered onto the circuit board through two pins.

2. Bolt type: CSD***M series coaxial shunt is fixed on the circuit board with bolts and nuts.

Comparing with the wire type CSD***A/B series coaxial shunt, the bolt type CSD***M series can be assembled and disassembled easily. Users only need to plug it in the holes on a PCB and tighten a nut.

The bolt fixing mechanical structure of the CSD***M series adopts a new high reliability design, which can lower the possibility for the users to break the inner structure of the coaxial shunt by over tightening the bolt.
