SPM4020T-3R3M-LR電感器線圈扼流圈的固定電感器規(guī)格書PDF中文資料

SPM4020T-3R3M-LR屬于電感器線圈扼流圈的固定電感器。由東電化（中國）投資有限公司制造生產(chǎn)的SPM4020T-3R3M-LR固定電感器電感器也稱為線圈、扼流圈或電抗器，是一種無源雙端電子元件；當電流流過其中時，它會在磁場中儲存能量。當電流變化時，磁場會在導體中感應出電壓。感應電壓的極性與產(chǎn)生它的電流變化相反。電感的單位是亨利 (H)。安裝選項包括表面、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
