Product Description
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.
