SHA Series Datasheet

Precision manganin copper alloy shunt

Shunt Sha product image

 

The Ohmite SHA series shunts can support up to 1KA of rated current. Due to its special alloy material, the SHA series has good long-term stability and can withstand pulse current several times higher than the rated current. The special heat treatment process of the SHA series enables a low current coefficient providing stability in high current applications. The SHA series has thermal potential of less than 0.5pV/°C to copper, and has little effect on the voltage output of the millivolt level. The flat structure of the SHA series makes the inductance less than 3nH creating a shunt compatible with high  frequency applications.
