We have developed a common mode choke coil at Seiwa Electric. By using a new nano-crystal material for the core, we can achieve higher effectiveness. By switching to the nano-crystal common mode choke coil, it is possible to reduce the capacitance of surrounding capacitors, allowing for space-saving designs. (Nano-Crystal Core) This alloy has an ultra-fine crystalline grain structure, high saturation magnetic flux density, and excellent soft magnetic properties, making it suitable for applications related to noise, power supply, and communications. (Main Applications) - Noise-related: Noise filters (common mode chokes), zero-phase reactors, bead cores - Communication-related: Pulse transformers for LAN - Power supply-related: Switching power supplies, smoothing chokes, choke coils for active filters, cut cores for inverter transformers - Sensor-related: Current sensors, zero-phase current transformers, leakage circuit breakers - Pulse power-related: High-voltage pulse transformers - Others: Inverter transformers for vehicles (Features) - High saturation magnetic flux density - High permeability - Low core loss - Low magnetostriction (zero magnetostriction is also possible) - Good temperature characteristics - Small aging changes - Good high-frequency characteristics
