FMK in an electronic parking brake

Isabellenhütte precision resistors monitor current profiles in electronic parking brakes

The latest trend in the automotive industry is downsizing. Smaller and more compact components save space, reduce weight and ultimately cut fuel consumption and carbon emissions. Despite the smaller size, the components still have to meet the customary standards; miniaturisation while maintaining comparable performance is the key.
Isabellenhütte Heusler GmbH & Co. KG specialises in active current sensing. A few years ago, it launched its FMx series in shunt form to cater to the demands of the market and plug a gap in its product range of low-ohm, compact resistors.
The FMx series covers resistance from 2 to 6 milliohms. Using the example of the electronic parking brake, a component that has become ubiquitous in all types of new car – right down to small family vehicles – as an example, this case report demonstrates what’s possible with this new range of shunt technology.
