BL01RN1A1D2屬于濾波器的鐵氧體磁珠芯片。由村田制作所制造生產(chǎn)的BL01RN1A1D2鐵氧體磁珠和芯片鐵氧體磁芯是旨在防止高頻噪聲或 EMI（電磁干擾）的設(shè)備。這些鐵氧體磁芯用于放置在電路內(nèi)。關(guān)鍵特征包括濾波器類型（差分、信號或電源）、線路數(shù)、最大額定電流、阻抗和指定頻率，以及安裝類型（自由懸掛、表面貼裝或通孔）。

BL01/02/03 series are ferrite beads with lead wires to

produce a high frequency loss for suppression of

noise. Simple construction and easy-to-use, effective

for low impedance circuits such as power supplies and

grounds. Effective also for preventing overshoot and

undershoot of digital signal in clocks or the like,

and suppressing the higher harmonic wave. Suitable for

prevention of abnormal oscillation at high frequency

amplifying circuit.
