SPM4020T-4R7M-LR电感器线圈扼流圈的固定电感器规格书PDF中文资料

SPM4020T-4R7M-LR属于电感器线圈扼流圈的固定电感器。由东电化（中国）投资有限公司制造生产的SPM4020T-4R7M-LR固定电感器电感器也称为线圈、扼流圈或电抗器，是一种无源双端电子元件；当电流流过其中时，它会在磁场中储存能量。当电流变化时，磁场会在导体中感应出电压。感应电压的极性与产生它的电流变化相反。电感的单位是亨利 (H)。安装选项包括表面、通孔和底座。

Inductors for Power Circuits Wound Metal

Overview of SPM4020-LR Type

FEATURES

○ Magnetic shield type wound inductor for power circuits using a metallic magnetic material.

○ Low-profile product.

○ Compared to ferrite wound type inductors, it is possible to achieve large current, low Rdc, and compactness.

○ Low inductance variance in high-temperature environments with good DC superimposition characteristics.

○ Metallic magnetic material is used, and the structure has an integrated molded coil, so hum noise is lower than with core adhesive coils.

APPLICATION

Tablet terminals, note PCs, HDDs, servers, VRMs, compact power supply modules, other
