Nanocrystalline tape wound cores made of NANOPERM®

Our tape wound cores are based on nanocrystalline softmagnetic material NANOPERM® which provide a unique combination of high permeability and low losses at high frequencies. This is why they are suitable for many applications, such as

• Common Mode Filter Chokes
• Absorber Cores for suppression of Motor bearing currents
• SMPS transformers
• Push-Pull-Transformers for Power Transistors
• HF Current transformators
• High precision Energy Meters
• Current Sensors
• Spike Killer Cores for dI/dt limitation

Standard designs for Core finishing:

• Plastic box (material UL listed, QMFZ2 E41871 (OBJS2 E209169) and QMFZ2 E41938)
• Epoxy coating (material UL listed, QMFZ2 E343402)
• Optional: Additional edge protection for Epoxy coated Cores by foil bandage (material UL listed, QMFZ2 E53895) ('epoxy+').

Note:
In case of wire winding we recommend not to wound the wire directly on the epoxy surface, but to cover the core with foil first!
