Technical FAQ
M-EI-UI is a modular system of coil former elements, frames and housings for laminated core transformer applications. It supports M, EJ and UJ geometries and protection class transformer designs.
Frames and housings support creepage and clearance distance requirements, mechanical fixation and insulation between primary and secondary windings and between windings and laminated cores.
Protection class designs A, B and C describe different system configurations using coil former elements, frames and housings to meet insulation, creepage and clearance requirements.
The components are typically made from glass-fibre reinforced PA66 p6g with RTI +125°C. Special materials such as radiation cross-linked versions are available on request.
Depending on configuration, solderable M-EI-UI components can support short-term soldering temperatures up to +350°C for up to 2 seconds.
Yes. The modular construction allows primary and secondary areas to be wound in separate process steps depending on the selected component system.
