YNR4030-150M — 15µH 磁胶屏蔽功率电感产品概述

一、概述

YNR4030-150M（品牌：YJYCOIN / 益嘉源）是一款表面贴装（SMD）磁胶屏蔽功率电感，封装尺寸为4.0×4.0×3.0 mm。额定电感值为15 µH（±20%），专为开关电源和电源滤波场合设计，兼顾体积小、抑制电磁辐射和大电流承载能力。

二、主要参数

电感值：15 µH ±20%
额定电流（Ir）：1.11 A（温升控制下持续工作电流）
饱和电流（Isat）：1.65 A（电感下降10%时的参考饱和点）
直流电阻（DCR）：约190 mΩ
类型：磁胶屏蔽电感（屏蔽良好，外泄磁场小）
封装：SMD，4×4×3 mm

三、产品特性

低矮型结构，适合高密度贴装与轻薄设备
磁胶屏蔽设计降低互扰，利于 EMI 控制
较高的饱和电流保证在开关瞬态下电感稳定性
标准化封装便于自动贴片与回流焊工艺

四、典型应用

降压/升压/SEPIC 开关调压模块的电感元件
电源滤波、输入/输出电感卷积（LC 滤波）
便携式电子、智能终端、物联网节点、LED 驱动与通信设备的功率管理板

五、选型与布局建议

关注实际工作电流与额定电流差距，尽量留有余量以控制温升和损耗；若工作电流接近或超过 1 A，应校核 I^2·DCR 损耗（DCR=190 mΩ）与效率影响。
对于脉冲大且频繁的应用，参考饱和电流 1.65 A 以避免电感值显著下降。
PCB 布局应缩短电感与开关管、整流二极管之间的回流路径，减小寄生环路面积；必要时加热散热铜箔或散热过孔。
使用推荐的回流焊曲线与制造商提供的温度限制参数，避免过热导致磁芯或胶体性能退化。

本型号适合在空间受限且要求良好电磁兼容与中等电流能力的电源设计中使用，如需更高电流或更低 DCR，可咨询供应商提供同系列更高规格型号。
