Technical FAQ
EP coil formers are winding bodies for enclosed pot core geometries. They are used for compact transformers with high inductance, low stray fields and space-saving PCB integration.
EP cores have a closed magnetic structure. This supports low stray fields and compact transformer designs with favorable electromagnetic behavior.
NORWE EP coil formers use glass-fibre reinforced PET rtg natural with RTI +155°C. Special materials and radiation cross-linked versions are available on request.
Depending on configuration, EP coil formers support short-term soldering temperatures up to +350°C for up to 2 seconds.
SB-EP clamping brackets are steel components used to connect EP ferrite core halves. One clamping bracket is required per core set and coil former.
Radiation cross-linking can help preserve mechanical properties under short, high thermal peak loads during high-temperature soldering processes and may reduce breakage risk.
