BLM15AG221SN1滤波器的铁氧体磁珠芯片规格书PDF中文资料

BLM15AG221SN1属于滤波器的铁氧体磁珠芯片。由村田制作所制造生产的BLM15AG221SN1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

function 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.

The nickel barrier structure of the external

electrodes provides excellent solder heat resistance.

BLM_A series generates an impedance from the

relatively low frequencies. Therefore BLM_A series is

effective in noise suppression in a wide frequency

range (30MHz to several hundred MHz).
