NFA18SD187X1A45L滤波器的EMI/RFI滤波器（LCRC网络）规格书PDF中文资料

NFA18SD187X1A45L属于滤波器的EMI/RFI滤波器（LCRC网络）。由村田制作所制造生产的NFA18SD187X1A45LEMI/RFI 滤波器（LC，RC 网络）该系列产品将几种无源元器件集成到单个装置中，可用于产生电流的频率依赖性阻抗。尽管有其他类型，但大多数都是用于抑制不必要高频信号传输的低通型，否则可能会导致干扰或意外操作。

1. NFA18SD series is LC combined noise suppression

filter whose noise suppression curve is

very steep and deep in spite of its small shape.

2. This product has additional function as common mode

choke coil. It works as a common mode choke coil at

low frequency range, also works as a LC filter at

high frequency range. This combination results good

noise suppression effect without the affection to

differential signal waveform.

3. This product has good noise suppression effect from

470MHz (for digital TV) to 2GHz. (for mobile phone)

This function improves the sensibility of digital

TVs or mobile phones.

4. Four circuits are built in 1.6x0.8mm chip size,

it saves the large amount of mounting space.
