BLM18BD252SN1D滤波器的铁氧体磁珠芯片规格书PDF中文资料

BLM18BD252SN1D属于滤波器的铁氧体磁珠芯片。由村田制作所制造生产的BLM18BD252SN1D铁氧体磁珠和芯片铁氧体磁芯是旨在防止高频噪声或 EMI（电磁干扰）的设备。这些铁氧体磁芯用于放置在电路内。关键特征包括滤波器类型（差分、信号或电源）、线路数、最大额定电流、阻抗和指定频率，以及安装类型（自由悬挂、表面贴装或通孔）。

The chip ferrite beads BLM series is designed to

work nearly as a resistor at noise frequencies,

which greatly reduces the possibility of resonance and

leaves signal wave forms undistorted.

BLM series is effective in circuits without stable

ground lines because BLM series does not need a

connection to ground.

BLM_B series can minimize attenuation of the

signal waveform due to its sharp impedance

characteristics. Various impedances are available to

match signal frequency.

The nickel barrier structure of the external

electrodes provides excellent solder heat resistance.
