Application
Electronic Power Steering
As a safety-relevant element in the vehicle, electronic steering is one of the classic applications for shunt-based current measurement.

Precise current measurement in vehicles
As current measurement using a shunt resistor requires direct integration in the measuring section and thus guarantees a highly accurate measurement result, the shunt is preferred by car manufacturers in this application.
Market-leading shunt solutions
Due to the specific challenge (lack of space, high technical requirements and use of DCB substrates), Isabellenhütte's 2- and 4-terminal shunt solutions have established themselves as market leaders in the automotive industry. This means that our electron beam welded shunts for high rated currents and contact point temperatures can be used on both standard FR4 boards and DCB boards.

We recommend the following shunt resistors (mainly 0.5 mOhm) for this application:
With regard to the temperature cycles that occur with DCB ceramics, the BVB and BVN shunts are preferred and recommended by manufacturers due to their increased design. You also benefit from an improved TCR value with the 4-terminal shunt technology.
Low thermoelectric voltage
By using optimal material combinations and high-precision alloys, very low thermal stresses can be achieved, minimizing measurement error.
Lowest error susceptibility
Our products impress with the lowest failure rate and therefore a high level of safety for the end user.
High load
capacity
Experience and simulation as part of the development process ensure that our shunts are highly durable.
