FNR6045S100MT 产品概述

一、产品简介

FNR6045S100MT 是长江微电(cjiang)推出的一款功率级磁胶屏蔽贴片电感,标称电感值 10 μH(±20%)。器件采用 SMD 封装,外形尺寸为 6×6 mm,针对中低频开关电源和电流较高的滤波场合进行了优化设计,具备较好的屏蔽特性与机械强度,适合集成度较高的电源模块与工业类应用。

二、主要技术参数

  • 电感值:10 μH,公差 ±20%
  • 额定电流(Ir):2.7 A(连续额定)
  • 饱和电流(Isat):3.5 A(典型值)
  • 直流电阻(DCR):62 mΩ(典型值)
  • 类型:磁胶屏蔽电感(屏蔽、环氧封装)
  • 封装:SMD,6×6 mm
  • 品牌:cjiang(长江微电)
  • 型号:FNR6045S100MT

三、性能特点

  • 抗饱和设计:较高的饱和电流(3.5 A)可在短时脉冲或启动瞬态下保持较稳定电感,降低电感值突降风险。
  • 良好屏蔽性:磁胶屏蔽结构可有效抑制外泄磁通,减少对周边敏感电路的干扰,利于高密度布局。
  • 稳定的温升与机械可靠性:SMD 环氧封装提高振动与冲击耐受性,适合自动化贴装生产。
  • 适度功耗:DCR 为 62 mΩ,连续工作在额定电流下的铜损约为 0.45 W(P = I^2·R),设计时需考虑散热与温升。

四、典型应用场景

  • DC-DC 降压(Buck)及升压(Boost)开关电源输出或输入滤波
  • 电源模块的输入滤波与能量储存单元
  • LED 驱动电源、车载电子(非高温高冲击关键部位)
  • 工业电源与通信设备中的 EMI 抑制与电能传输

五、封装与 PCB 布局建议

  • 尽量缩短电感与功率管、整流器之间的连接走线,减小环路面积以降低 EMI。
  • 在电感两端增加足够宽的焊盘并考虑多过孔导热(若板厚允许),帮助散热。
  • 避免在电感下方布置敏感模拟信号线或高阻电阻,利用器件自身屏蔽特性同时保持合理间距。
  • 推荐在靠近的输入/输出端放置适当的旁路电容以稳定工作点并抑制纹波。

六、选型与使用注意事项

  • 持续电流应以内定额定电流(2.7 A)为基准,并根据环境温度、通风与封装热阻适当降额;对有较大脉冲或峰值电流的应用,应以饱和电流(3.5 A)作为短时承受极限并保留裕量。
  • 由于 DCR 相对较高,若应用对效率敏感或需要更低损耗,应考虑更低 DCR 的同类型号或并联设计(需谨慎评估磁耦合与均流)。
  • 对电感值精度要求高的场合(±20% 较大)应在电路中预留补偿空间或选择更精密型号。

七、测试与可靠性建议

  • 建议在目标工作温度与调制条件下进行温升测试,确认在额定电流下的温度峰值不超出器件及周边元件限制。
  • 对于有高频开关或快速电流转换的系统,应测试实际电感随直流偏置与交流频率的变化(L vs I, L vs f),以验证滤波与能量传输性能。
  • 进行振动与焊接热循环测试以评估长期可靠性,尤其在车载或工业环境中。

总结:FNR6045S100MT 以 10 μH、2.7 A 连续电流与 3.5 A 饱和电流为主要性能点,适合中等功率密度的开关电源与滤波应用。设计时需关注 DCR 导致的功耗与温升,并对峰值电流、布线和散热做出相应安排,以确保长期稳定运行。若需更低损耗或更紧的电感公差,可考虑同品牌或其他厂商的替代型号。

Buyer sourcing scenarios

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.
