(1/1) Ferrite for EMI Suppression High Permeability Material HF90 This ferrite material has high magnetic permeability and a peak impedance at a lower frequency band than conventional materials. It also has good noise absorption characteristics in the AM band (100kHz to 1.6MHz). FEATURES • Good noise absorption characteristics in the frequency band from 100kHz to 1.6MHz. • Replacing metal ferrite with this material can reduce cost. • Effective noise suppression for devices with inverters. • Compatible with various shapes and sizes for different use conditions.
