贴片电感怎么选型?
贴片电感的选型需要考虑以下几个因素:
1. 电感值:根据电路需求选择合适的电感值,电感值一般在几微亨到几毫亨之间。
2. 额定电流:根据电路的最大工作电流选择合适的贴片电感。贴片电感的额定电流一般在几百毫安到几安之间。
3. 相关尺寸:根据电路的空间限制选择合适的贴片电感,包括长度、宽度、高度等尺寸。
4. 频率特性:根据电路的工作频率选择合适的贴片电感,一般需要注意电感的自谐振频率和串、并联谐振频率等。
此外,还需要考虑以下性能参数:
电感量:是电感的标称感值,由于磁导率和分布电容的存在,感量会随频率的变化而变化。电感的精度一般为M(±20%) 档或者N(±30%) 档。
直流电阻:指产品电极之间所用漆包线的总的直流电阻。
直流重叠电流:指电感在连续通直流电流的情况下,电感的电感量会下降,一般按照下降30%的时候的电流值来设定规格。
温升许容电流:指电感在连续通直流电流的情况下,电感的表面的温度会上升,一般按照上升40℃的时候的电流值来设定规格。
自谐频率:由于电感及电感本身分布电容的相互作用,使电感在某频率下达到谐振,该谐振频率就是电感的自谐频率,贴片电感要求使用在自谐频率以下。

【产品】高电流、低直流电阻的紧凑型绕线式贴片电感WSA系列
WSA系列电感是AiT推出的一款绕线式贴片电感,具有可通过电流大,直流电阻低,效率高,可靠性高,外形紧凑而薄占用空间少,高耐热性适合回流焊。主要应用于手机、电脑、硬盘驱动器和其他电子设备等。
贴片电感的额定电流分享
贴片电感的额定电流有“基于自我温度上升的额定电流”和“基于电感值的变化率的额定电流”两种决定方法,分别具有重要的意义。“基于自我温度上升的额度电流”是以元件的发热量为指标的额定电流规定,超出该范围使用时可能的会导致元件破损及组件故障。
【产品】感值范围0.68μH~1000μH的贴片电感NR6045系列,额定电流范围为11A~0.32A
