3.00 * 0.35 mm Rectangular Enameled Copper Wire
3.00x0.35mm rectangular enameled copper wire
Meet design requirement of lower height, smaller size, lighter and more power.The wire is widely used in electronice, military electronic, spaceflight.
Bigger surface area than round wire at the same cross section, reducce skin effect effectively, decrease current loss, that/s better to adpat high frequency transduction.
High space factor and fill in ratio, greatly reduce resistance, pass bigger current, get higher Q value that is better to adapt high current load.
The product that use rectangular wire has such features: simple in structures, good heat dissipation ,stable performance, stablegood consistency. Maintain stable temperature rise current and saturation current in high frequency and high temperature environment anti EMI, small vibration, low noise and install in high density.
APPLICATIONS
- Small type motor ( Electric household appliance, Toys & etc. )
- Transformer for measuring instrument
- For communication : High frequency coil for transformer, Coil for power source transformer
- Coil-small transformer, TV, speaker & etc.
