BLA31BD221SN4D滤波器的铁氧体磁珠芯片规格书PDF中文资料

BLA31BD221SN4D属于滤波器的铁氧体磁珠芯片。由村田制作所制造生产的BLA31BD221SN4D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）。

1. BLA31A/B have 4 circuits in 3.2×1.6mm body with

0.8mm pitch.

2. Provides attenuation across a broad frequency

range. Two types of impedance are available

which meets general signal line and high speed

signal line.

3. Original inner electrode structure enables extra

low crosstalk.

4. The nickel barrier structure of the extermal

electrodes provides excellent solder heat

resistance. Both flow and reflow soldering

methods can employed.
