C Core Product Description
Amorphous C core
Amorphous C core (Amorphous Cut Core) made from amorphous Fe-based alloys offer an interesting combination of high saturation flux density and low magnetization losses, therefore they are especially suitable for PFC (Power Factor Correction) or storage chokes
- High Saturate induction: Reducing Core Volume
- Rectangular Structure: Easy for coil assembling
- Core Cutting: Good for anti-DC-bias-saturation
- Low core loss: Anti-temperature-rising (1/5 ~ 1/10 compared to silicon steel)
- Good stability: Stable working from -50℃ to 130℃
- Reactor cores for PV inverter
- Filter reactor of high-frequency super switching power supply
- Mid-high frequency switching power supply
- Major transformer of UPS Power supply
Silicon Steel C Core
High-quality CRGO steels with characteristics of low iron-loss and high permeability in thickness of 0.05mm, 0.08mm, 0.1mm, 0.23mm, 0.27mm, 0.3mm, and 0.35mm.
A closed flux path with an open structure can be formed by combining the two halves together. The bobbin and core can be produced separately and then place the core in the bobbin, which can effectively reduce production time.
All cores, unless otherwise stated, are individually tested to guarantee that they quailfy national standards and specifications.
C-core comes in various specifications and is widely used in 50Hz and 400Hz transformers, current transformers, reactors, chokes, and other magnetic components of electronic equipment.
Nanocrystalline C core
Nanocrystalline C core is upgrade product of amorphous c core, with high saturation flux density, low coercivity, low core loss, low noise, higher frequency up to 20KHz, suitable for main power transformer, audio transformer, output inductor, boost PFC choke coil. Can replace ferrite cores, permalloy cores, silicon steel cores.
Characteristic
- High saturate induction - Reducing core volume
- Rectangular form - Easy to mount coils
- With air gap - Excellent anti-bias current ability
- Low core loss - Low temperature rise
- Good temperature stability
- Applied to solar inverters, wind power inverters
- Output filter or inductor cores in high frequency large power supplies
- Transformer cores in switch mode power supplies
