NFA18SL137V1A45滤波器的EMI/RFI滤波器（LCRC网络）规格书PDF中文资料

NFA18SL137V1A45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NFA18SL137V1A45EMI/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. NFA18SL series is LC combined EMI filter whose

feature is compact size, steep and deep insertion

loss curve.

2. [Cutoff frequency 300Mz, 400MHz, 480MHz type]

Good nise suppression effect at frequency range over

800MHz, which are important to improve sensitivity

of mobile phones.This feature enables effective noise

suppression at LCD lines or camera module lines.

[Cutoff frequency 50Mz, 130MHz, 180MHz, 200MHz type]

This type also have good performance at UHF band

in addition to products mentioned above.

This feature is suitable to improve sensitivity

of digital TVs.

[Cutoff frequency 220MHz type]

This type is improved the performance at frequency

range from 800MHz to 3GHz in addition to products

mentioned above.

[Cutoff frequency 350MHz type]

Reduced capacitance to 4pF typ. This enables low

impact to signal waveform and high noise suppression

performance.

3. Various cutoff frequency has made to control rise

time and fall time of waveform.

4. 4 circuits are installed in compact shape of

1.6x0.8mm. Greatly reduces footprint.
