FNR5040S100MT 产品概述 — cjiang(长江微电) 10µH 磁胶屏蔽功率电感

一、产品简介

FNR5040S100MT 是长江微电(cjiang)推出的一款表面贴装磁胶屏蔽功率电感,标称电感值 10µH,公差 ±20%。器件采用 5×5mm SMD 封装,结合磁性胶体与屏蔽结构,兼顾磁性能与抗干扰能力,适用于空间受限且要求抑制辐射与集成度较高的开关电源和电源滤波电路。

二、主要电气参数

  • 电感值:10 µH(±20%)
  • 额定电流(I rms):2.35 A(在允许温升和电感衰减控制范围内)
  • 饱和电流(Isat):2.7 A(在该电流下感量显著下降)
  • 直流电阻(DCR):约 83 mΩ
  • 类型:磁胶屏蔽电感(磁性胶体封装、屏蔽结构)
  • 封装:SMD,5×5 mm

三、产品特点与优势

  • 高电流承载:额定电流 2.35A,饱和电流 2.7A,适合中小功率降压/升压稳压器应用。
  • 较低直流电阻:83 mΩ 有助于降低导通损耗,提高转换效率。
  • 屏蔽设计:磁性屏蔽和胶体封装减少磁通泄漏,降低对邻近器件的干扰与串扰,有利于 EMI 控制。
  • SMD 封装:5×5mm 小型化封装,便于自动贴片与高密度 PCB 布局。

四、典型应用场景

  • DC-DC 降压/升压转换器(中低功率)
  • 手机、平板及便携设备的电源滤波与储能元件
  • 工业控制与网络设备的电源模块
  • EMI 抑制与输出滤波网络

五、选型与应用建议

  • 电流裕量:实际应用中建议按额定电流 2.35A 或更低选择,以避免长期接近饱和与过热;对于脉冲电流,应关注峰值与平均值并预留裕量。
  • 温升与散热:器件 DCR 会引起功耗(I^2·R),请结合 PCB 散热、铜箔面积与周围器件安排评估温升。
  • 饱和特性:若电路存在短时大电流脉冲,应确认在峰值电流下电感不会进入严重饱和状态(Isat = 2.7A 给出参考)。
  • 频率响应:根据工作频率测量或咨询厂方获取实际电感随频率的衰减与自谐频率(SRF),以保证在工作带宽内电感满足滤波要求。

六、封装与焊接注意事项

  • 建议按常规 SMD 回流焊工艺操作,并遵循 PCB 与焊膏厂商推荐的回流曲线;避免重复高温或超出器件承受温度。
  • 在布局时为该电感预留适当铜箔面积以改善散热,并注意靠近关键敏感信号的屏蔽与间距。
  • 存储与搬运避免受到强烈机械冲击或潮湿环境,必要时按常规电子元器件防潮处理。

七、验收与测试建议

  • 到货后建议进行外观检查、DCR 测量与标称电感值抽样检测;在目标电路中做温升与电流冲击测试,验证长期可靠性。
  • 若对 EMI 或高频性能有严格要求,建议测量器件在目标频段的阻抗与自谐频率曲线,或向供应商索取完整电感频响曲线。

总结:FNR5040S100MT(10µH,±20%,2.35A,Isat 2.7A,DCR 83mΩ,5×5mm 磁胶屏蔽 SMD)适合中小功率电源模块与对 EMI 有抑制要求的场合。合理预留电流与热裕量、并结合实际频响测试,可在高密度电源设计中取得良好表现。若需器件完整数据手册或频率特性曲线,可联系长江微电技术支持获得进一步资料。

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.

Replenishment inquiry Typical RFQ workflow
