FNR6045S300MT 产品概述

一、产品简介

FNR6045S300MT 是长江微电(cjiang)推出的一款磁胶屏蔽功率贴片电感,额定电感值为 30 µH,公差 ±20%。器件采用 SMD 封装,外形尺寸为 6×6 mm,针对中小电流电源前端、滤波与能量储存应用优化设计,兼顾体积、磁屏蔽和机械强度。

二、主要电气参数

  • 电感值:30 µH(±20%)
  • 额定电流(Ir):1.6 A(连续工作电流建议按此值或更低使用)
  • 饱和电流(Isat):1.8 A(磁通密度接近饱和时测得)
  • 直流电阻(DCR):约 172 mΩ
  • 类型:磁胶屏蔽电感(磁芯采用粘合/注胶工艺,增强屏蔽与抗振动性能)
  • 封装:SMD,6×6 mm

三、特点与优势

  • 高性价比:在小体积平台上提供 30 µH 的电感储能能力,适合成本敏感型设计。
  • 良好屏蔽性:磁胶屏蔽结构降低外泄磁场,对周边敏感器件干扰更小,利于高密度布板。
  • 稳定性与可靠性:粘合工艺提高机械强度,抗震动、抗热循环性能优于无胶结构。
  • 易于贴片加工:标准 SMD 封装兼容常规回流焊工艺和自动贴装流程。

四、典型应用场景

  • 低功耗 DC-DC 降压/升压稳压电路(中小电流档位)
  • 电源滤波与输出滤波(尤其在空间受限的电源模块)
  • LED 驱动与便携设备供电管理
  • 物联网终端、工控模块、电池管理系统的电磁兼容(EMC)设计中

五、设计与选型建议

  • 电感衰减:在接近额定电流时,实际电感会因磁饱和而下降,设计时需考虑直流偏置对电感值的影响,必要时留有裕量或选择额定电流更高的型号。
  • 损耗与效率:DCR 为 172 mΩ,电流较大时会产生显著 I²R 损耗,影响温升和效率。若对效率要求高,应评估热量与散热措施或选用 DCR 更低的型号。
  • 耐热与回流:遵循器件的回流焊温度曲线和PCB焊盘设计规范,避免超温影响封装与胶体性能。
  • 布局:为充分利用屏蔽特性,应注意电感与敏感信号线或高频放大器的隔离;输出滤波时配合合适的电容和布局可降低辐射与环路阻抗。

六、可靠性与测试要点

  • 在样机验证阶段,应进行电流-电感特性测试(L vs Id)、温升测试以及长期功率循环试验,确认在目标工作点下稳定性。
  • 做电磁兼容(EMC)和浪涌试验,验证屏蔽效果及在突发脉冲下的行为。
  • 注意在潮湿或高温环境下胶体长期可靠性,必要时进行环境应力筛选(HAST、Thermal Cycling)测试。

七、采购与替代方案

  • 选型时请确认具体封装尺寸、包装方式(卷带/托盘)与最小订购量。样品评估建议先索取小批量样品验证。
  • 若需更高电流承载或更低 DCR,可考虑同类尺寸下额定电流更高或采用多匝更粗导线的功率电感;若要求更高感值稳定性,可考虑磁芯材料或结构不同的无胶或叠片电感。

总结:FNR6045S300MT 以 30 µH、1.6 A 的额定能力和 6×6 mm 的紧凑封装,适合空间受限且需良好屏蔽与机械强度的中小功率电源滤波应用。选用时应重点考虑直流偏置下电感衰减、DCR 导致的损耗与散热,以及回流焊与环境可靠性验证。若需更详细的电气图表或设计资料,可提供进一步参数与测试数据以便评估。

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
