YNR6045-221M 产品概述

一、产品简介

YNR6045-221M(品牌:YJYCOIN / 益嘉源)是一款面向电源应用的磁胶屏蔽功率电感,封装为SMD,外形尺寸6.0 × 6.0 × 4.5 mm。主要电气参数为额定电感值220 µH(±20%),额定电流590 mA,饱和电流Isat 700 mA,直流电阻(DCR)834 mΩ。该器件以磁屏蔽结构为特点,适合空间受限且对磁干扰有一定要求的开关电源、电源滤波与能量储存场合。

二、主要电气特性

  • 电感值:220 µH,公差 ±20%(适合较大电感量需求的低频或低开关频率设计)。
  • 额定电流(Irated):590 mA(器件在该电流下长期工作温升与性能保持的参考值)。
  • 饱和电流(Isat):700 mA(在接近该电流时电感量会明显下降,影响储能能力)。
  • 直流电阻(DCR):834 mΩ(直流损耗与效率的重要指标)。
  • 封装与结构:SMD 贴片,尺寸 6×6×4.5 mm,磁胶屏蔽结构减小外泄磁场并降低对周围器件的干扰。

提示:电感在施加直流偏置电流时会出现电感量下降(直流偏置效应),在设计时需评估工作电流下的实际电感值及其对系统性能的影响。

三、功耗与热管理(示例计算)

DCR 导致的铜损(近似)为 P = I^2 × DCR。

  • 在额定电流 0.59 A 时:P ≈ 0.59^2 × 0.834 Ω ≈ 0.29 W。
  • 在饱和电流 0.70 A 时:P ≈ 0.70^2 × 0.834 Ω ≈ 0.41 W。

由此可见,在接近或超过额定电流时器件损耗显著,应考虑散热路径与周围温度对额定电流的影响。建议在布局中留出散热铜面积并避免把发热器件密集堆放。

四、封装与 PCB 布局建议

  • 封装:SMD,6×6×4.5 mm,高度 4.5 mm。适合自动贴装与回流焊工艺。
  • 布局:将电感置于开关器件与输出电容之间、靠近开关节点以最小化回路面积。输入侧与输出侧走线尽量短、粗,减少串联电阻与寄生电感。
  • 接地与屏蔽:虽然器件为磁屏蔽结构,但仍建议在敏感模拟电路或高速数字电路附近留出合理隔离距离。
  • 焊盘与焊量:按照厂方推荐焊盘及回流曲线进行焊接,若无具体焊盘图,按常规SMD功率电感的焊盘加大铜箔有利于散热。

五、典型应用场景

  • 低频 DC-DC 降压/升压转换器(尤其开关频率不太高、需要较大储能的场合)
  • 电源输出 LC 滤波器、反向抑制与电流滤波
  • LED 驱动电源、便携设备电源模块
  • 工业控制与通信设备中对 EMI 有一定抑制需求的电源段

六、选型与设计注意事项

  • 根据工作频率与允许的电流纹波来选择电感值与电流等级:较高的电感值可减小纹波电流,但会增大体积与直流损耗。
  • 检查在最大峰值电流条件下是否接近 Isat,避免进入饱和区域导致电感量骤降与电流冲击。
  • 考虑效率与温升时,应权衡 DCR 与体积,若效率要求高可选用更低 DCR 的型号或并联/替代方案。
  • 若对 EMI 要求高,可利用磁屏蔽版本的优势,但仍需配合良好的布局与滤波设计。

七、可靠性与封装注意

  • 推荐采用标准无铅回流焊工艺(依据供应商回流曲线)。若长期暴露在高温/高湿环境,应参考厂家的存储与焊接建议(如干燥箱保存、MSL 等级确认)。
  • 在大电流长时间使用下,温升应通过实际测试确认不超过设计温限。

八、订购信息

  • 型号:YNR6045-221M
  • 品牌:YJYCOIN(益嘉源)
  • 封装:SMD 6×6×4.5 mm
  • 规格摘要:220 µH ±20%,额定电流 590 mA,Isat 700 mA,DCR 834 mΩ

如需更详细的磁性曲线(电感随直流电流的变化)、温升曲线或推荐焊盘设计图,建议向供应商或器件数据手册索取完整规格书与推荐实物图样进行验证。

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
