WAx Series – New Product Made from Roll Cladding Pre-Material
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. We recognized a growing demand for such components; small, very low values and relatively high rated power.
Isabellenhütte has closed a gap in our portfolio with this type of resistor in package sizes 1213, 2010 and 1206. This will be an extension to ISA-WELD® products and the new FMX series in terms of small size with lower values.
Why parts from a new manufacturing process? It started with a new requirement for an EV-Inverter power module where our customer needed a 0.5 mOhm part in addition to BVF-V-R001-1.0 (size 1213). The new pre-material is well suited for these types of resistors, so we took this opportunity and introduced the first roll cladding resistor called WAF-Z-R0005-1.0 as a solution. Additional resistance ranges of the 1213 (WAF) and 1206 (WAK) and 2010 (WAP) are in the planning stage.
