Import Tips
• Include EMI attenuation test reports (>40dB at 150kHz) proving suppression transformer application
• Specify nanocrystalline ribbon thickness and mu value for material verification against steel cores
• Register for transformer parts drawback programs if re-exported in finished assemblies
