Available Materials in 6H MnZn Ferrite Series

Standard materials: 6 H series

6H series are JSF's standard power material with low core loss and high saturation flux
density, and are suitable for wide range of transformers and choke coils for switching power
supply.6H20 is standard material with superior characteristics and high performance-cost
ratio. 6Hl O has higher permeability than 6H20 in room temperature, and is suitable for
switch-mode transformers and chokes with working frequency below 100kHz.

Additionally, HJS has developed new materials with lower core loss and higher magnetic
flux density, which satisfies latest requirements of digital and mobile electronics.Core loss of
new 6H40 material is around 25% lower than that of standard 6H20, and is suitable for
transfom记rs and choke coils for flat, low profile power supplies and AC/DC adaptors of
electronic equipments (such as notebook PC), which strictly require low temperature rise.

For transformers and choke coils of mobile electronic equipments, JSF has developed
6H41 material (bottom temperature of core loss curve 80°C) and 6H42(bottom
temperature 50°C), which enables low operation temperature of transformers while
reducing the volume of transformers and improving the efficiency of transformers.

What's more, 6H45 material with core loss 10% lower than that of 6H40 is also in lineup
of HJS.
