1、 体积更小；Miniature volume.
2、 漏磁小，不产生耦合，可靠性高；
No cross
coupling between inductors due to
low magnetic
shield
and high reliability.
3、无引线，不产生跟踪性，适合高密度表面贴装；
No lead, ideal for high density SMT installation, with no
directionality.
4、优良的可焊性及耐热冲击性，适合波峰焊及回流焊。
Superior solder ability and resistance to soldering heat, ldeal for
wave or reflow soldering.

1、在同样的尺寸下较插装磁珠可产生较高的阻抗值；
Under the same size，the multilayer chip beads produce higher
impedance than plug-in beads.
2、与传统的磁珠不同，片式磁珠无引线，只要简单的安
装到PCB板上就可抑制EMI和RFI；
These chip beads have substantial EMI.RFI suppression by simply
mounting them onto PCB.
3、 磁珠的形状和尺寸都符合EIA标准，可以利用SMT设
备进行自动贴装。
No lead, ideal for high density SMT installation, with no
directionality.
4、优良的可焊性及耐热冲击性，适合波峰焊及回流焊。
Superior solder ability and resistance to soldering heat, ldeal for
