FNR8040S471MT 功率电感（470µH ±20%，600mA）
一、产品简介
FNR8040S471MT 是长江微电（cjiang）出品的一款磁胶屏蔽型贴片功率电感，外形尺寸约为 8×8mm，标称电感值 470µH，公差 ±20%。该器件为面贴式（SMD）封装，适用于对体积、屏蔽性和可靠性有要求的中低电流电源滤波与储能场合。
二、主要参数
- 电感值：470µH ±20%
- 额定电流：600mA（连续工作参考值）
- 饱和电流（Isat）：700mA（接近或超过时电感量将明显下降）
- 直流电阻（DCR）：1.625Ω
- 类型：磁胶屏蔽电感（SMD，8×8mm）
- 封装：表面贴装
三、性能与优势
- 屏蔽结构：磁胶屏蔽设计降低漏磁，便于在密集电路板上使用，减小对周围器件的干扰。
- 中低频滤波与能量储存：470µH 属于较大感值，适合做电源输出滤波、功率级储能元件或直流降压/升压电路的能量传递环节。
- 良好的温升与可靠性：在推荐工作电流范围内长期稳定工作。需注意其相对较高的DCR，在高电流场合会产生显著功耗。
四、功耗与热管理
根据 DCR=1.625Ω，在额定电流 600mA 条件下的直流功耗约为 I^2·R = 0.6^2×1.625 ≈ 0.585W。此功耗会导致器件温升，应在电路设计时考虑散热路径与周边元件耐温要求。建议在可能的情况下预留热扩散铜箔或采用更低DCR的器件以降低发热。
五、典型应用场景
- 开关电源（DC-DC 降压/升压）输出滤波与能量暂存
- 电池供电设备的电源滤波与纹波抑制
- 器件对磁干扰敏感的工业和消费类电子设备
- 需要表面贴装、体积受限的电源模块
六、封装与焊接建议
作为 SMD 元件，推荐采用常规无铅回流焊工艺，遵循焊接曲线与基板预热要求以防止热应力损伤。贴装时避免对封装施加过大机械力；回流后建议进行可靠性与电感值抽检。杜绝多次重复回流及长期高温存放。
七、选型与使用注意
- 饱和电流（700mA）为上限参考，设计时应留有裕量，避免长期在饱和区工作导致性能下降。
- 若工作电流接近额定值，需关注功耗与温升，必要时优化散热或选用额定电流更高、DCR 更低的型号。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
