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
鈥?Good noise absorption characteristics in the frequency band
from 100kHz to 1.6MHz.
鈥?Replacing metal ferrite with this material can reduce cost.
鈥?Effective noise suppression for devices with inverters.
鈥?Compatible with various shapes and sizes for different use
conditions.
APPLICATIONS
鈥?Air conditioners, microwave ovens, refrigerators, and other
electrical home appliances.
鈥?Industrial equipment with inverters.
