- All specifications are subject to change without notice. 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.
APPLICATIONS
Air conditioners, microwave ovens, refrigerators, and other electrical home appliances. Industrial equipment with inverters.
