1 Applications correction, kind inductance coil, brand ESMT, Model 64 * 40 * 20, package plug-inductance, winding form between single wound, nature guide magnet core, core shape ring, operating frequency of the high frequency, Installation horizontal non-sealing, the plastic matrix material, the quality factor Q 10, inductance 5mH, tolerance + -25%, the inductive reactance XL 5K (Ω), distributed capacitance 0 (F), the nominal voltage of 0.3 (V), Rated current 40000 (mA 2. Nanocrystalline Alloy common mode inductance of magnetic saturation flux density Bs (T) 1.25 Initial permeability μi (Gs / Oe)> 8 × 104 maximum permeability μm (Gs / Oe)> 20 × 104 coercive force Hc (A / m) <2 Curie temperature Tc (℃) 560 crystallization temperature Tx (℃) 500 saturation magnetostriction coefficient λs <2 × 10-6 <2 continuous working temperature ℃ -50 130 residual magnetic flux density Br (T) 0.5 ~ 0.8 iron loss P (20kHz, 0.5T), (W / kg) <25 iron loss P (100kHz, 0.2T), (W / kg) <70 iron loss change rate ΔP (-50 ~ 125 ℃) <15% amorphous alloy material is a new advent in the 1970s, it is adopting international advanced super-quenching technology of liquid metal with 1 × 106 ℃ / s cooling rate of direct cooling having a thickness of 0.02 mm ~ 0.04mm solid strip to give an amorphous alloy having a short-range order, long-range disorder characterized by a combination of the atomic arrangement, does not have the crystal structure of a conventional metallic materials, so it has a different traditional materials The performance characteristics, such as excellent soft magnetic properties, corrosion resistance, abrasion resistance, high hardness, high strength, high resistivity, etc. Due to its excellent performance, simple production process, since the 1980s, as domestic and foreign materials science the focus of research and development and application of community, not only developed a soft material for the electronics industry, but also to develop an alloy material for other purposes, such as brazing materials, catalysts, construction materials, etc. of the late 1980s, scholars and material in developed on the basis of amorphous and nanocrystalline soft magnetic alloy material, the material has more excellent soft magnetic properties of amorphous common mode inductance characteristics: EMC common mode inductors filter with nanocrystalline (Nanocrystalline) Production EMC common mode inductors filter core, having a high saturation magnetic induction, high permeability, high inductance, good frequency characteristics and good temperature stability (long-term use in the temperature range of -50 ~ 130 ℃), etc. Applications: Common mode inductance choke is an important part of the switching power supply, inverter, UPS power supply and other equipment it works: When the operating current flow through the two coils wound to the contrary, the two cancel each other out to produce a magnetic field H1, H2, this Work damping coil current is mainly a small ohmic resistance and leakage inductance can be ignored without an operating frequency meter
