DLW21SN121HQ2滤波器的共模扼流圈规格书PDF中文资料

DLW21SN121HQ2属于滤波器的共模扼流圈。由村田制作所制造生产的DLW21SN121HQ2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. Small size: 2.0x1.2x1.2mm

2. Common mode impedance items of 67, 90 and 120 ohm,

and they can be used for various differential

signal lines, DLW21SN_HQ/DLW21SZ_HQ/DLW21SR_HQ series

matches line impedance of 100 ohm line.

3. This series can suppress noise for the

high-speed differential signal lines which are

used in digital AV interfaces, such as HDMI and DVI,

without damage to the signal wave.

4. DLW21SR670HQ2 is designed to correct line impedance

when ESD protection device is also used.

Applications

Common mode noise suppression of high speed

differential signal lines for HDMI, DVI, USB2.0,

IEEE1394, LVDS.

1. DVD Recorders

2. LCD TVs, LCD monitors

3. PCs

DLW21SR_HQ Series is suitable for receiver side of

HDMI interface line.
