YNR8040-101M 产品概述

一产品简介

YNR8040-101M 是益嘉源（YJYCOIN）出品的一款磁胶屏蔽功率电感，封装为SMD，外形尺寸8×8×4.2mm，标称电感值100µH，公差±20%。本型号针对开关电源和滤波电路优化，兼顾高感量与体积小型化的工程应用。

二主要特性

电感值：100µH ±20%
额定电流：1.0A（持续载流能力）
饱和电流（Isat）：1.15A（磁性开始明显饱和）
直流电阻（DCR）：290mΩ
结构：磁胶屏蔽，降低漏磁和外部干扰
封装：SMD，尺寸8×8×4.2mm，适合自动化贴装

三电气与热性能说明

在额定电流1A下，铜损约为P = I^2·DCR ≈ 0.29W，器件在连续工作时应考虑散热与温升。饱和电流1.15A为电感显著下降的门槛，建议在设计中对峰值电流留有裕量，避免工作于或超过Isat以免影响滤波性能。

四机械与工艺建议

器件为标准SMD封装，适用回流焊接。建议采用制造商推荐的回流曲线与温度档，焊盘设计预留足够的铜量以利于散热与机械强度。焊接后进行常规外观与X光检查。

五应用场景

适用于DC-DC转换器输入/输出滤波、EMI 抑制、电源线上滤波及小功率供电模块。因尺寸和电流等级适合便携设备、通信设备和工业控制低功率子模块。

六选型与替代注意

选择时关注峰值电流、占空比与温度环境。若系统存在较大突发电流或更低DCR要求，可考虑较高额定电流或更低DCR的型号。比对参数时重点看Isat、DCR与封装兼容性。

七可靠性与包装

建议按厂商提供的储存与潮湿敏感等级（MSL）储存，贴片前回流烘箱处理以去除吸湿。常规出货为托盘或卷带包装，便于SMT贴装与备件管理。

如需样品或更详细的典型电流-电感曲线、温升测试报告与回流焊工艺建议，可联系供应商获取完整数据手册和应用资料。
