DLW21SN121SQ2L滤波器的共模扼流圈规格书PDF中文资料

DLW21SN121SQ2L属于滤波器的共模扼流圈。由村田制作所制造生产的DLW21SN121SQ2L共模扼流圈共模扼流圈是一种电气滤波器，能阻止两条或更多条数据或电源线共有的高频噪声，但允许期望的直流或低频信号通过。共模 (CM) 噪声电流通常来自无用的无线电信号、非屏蔽电子设备、逆变器和电机等来源。如果不加以过滤，这种噪声会在电子设备和电路中带来干扰问题。

1. DLW21S series realizes small size and low profile. 2.0x1.2x1.2mm

2. High common mode impedance at high frequency effects

excellent noise suppression performance.

3. Various common mode impedance items of 67 to 920 ohm

can be used, considering noise level and signal frequency.

4. DLW21S series enables noise suppression for differential

signal line without distortion in high speed signal

transmission due to its high coupling.

5. Small dimension enables higher density packaging.

Applications

1. USB lines of PC, Peripheral equipment

2. LVDS lines of Note-PCs, LCDs

3. USB lines of Small digital AV equipment such as

digital cameras
