FMx & WAx APPLICATIONS
Isabellenhütte is offering an expanded line of precision resistors to help support these booming markets.
For innovators in the drone and e-cycle spaces, size and weight characteristic of key BMS components are important factors, along with an ability to reliably source precision resistors
in the 2 to 6 mOhm range.
The FMx Shunt Family
Makers of e-scooters, e-bikes, and all types of drones (UAVs) are turning to Isabellenhütte for components such as our full-metal, direct-solder shunts, the FMx Shunt Family.
By incorporating FMx into their aircraft and cycles, designers allow for automated inspection of soldering points—a huge factor in quality control and ease of manufacturing.
Despite the reduction in complexity, the FMx range still offers the same high performance quality as our existing high-ohmic products. This is supported by the high-grade, massive resistance materials—our propriety alloys—which supply very good long-term stability, low temperature coefficients and low thermoelectric voltages.
The WAx Series of Roll-Clad Resistors
Initially custom developed as a 0.5 mOhm resistor for EV-inverter power modules, we’ve adapted the original design to leverage the functionality of today’s amplifiers—which can help minimize generated power loss, and measure higher currents in smaller footprints.
The WAx Series are our first roll cladding resistors, and encompass resistance ranges from 0.5 mOhm to 1 mOhm.
New amplifiers make it possible to use low resistance values to measure current in many applications. This has two effects; one is to minimize the generated power loss and the second is to measure a higher current with space-saving parts.
A reliable supplier—ready for the coming wave
As drone, bike, and scooter manufacturers move into aggressive growth mode, another critical aspect of supplier relationships is reliability of supply. Here, Isabellenhütte is able to point to our proven global access to materials and labor that has provided a reliable hedge for our customers. We have had no significant supply-chain disruptions due to the pandemic or logistics bottlenecks.
