FXL0530-4R7-M — 5A 4.7µH 一体成型功率电感（长江微电）
一、产品概述
FXL0530-4R7-M 为长江微电（cjiang）推出的一款表面贴装一体成型功率电感，标称电感值 4.7µH（±20%），额定电流 4.5A，饱和电流 Isat 5A，直流电阻（DCR）约 60mΩ。封装为 SMD，尺寸约 5.2 × 5.4 mm，适合中小功率开关电源与点位供电（POL）模块使用。
二、关键参数
- 电感值：4.7µH ±20%
- 额定电流：4.5A（连续工作）
- 饱和电流：5A（Isat，具体判定依据请参见厂方资料）
- 直流电阻：≈60mΩ（影响铜损与温升）
- 封装：SMD，一体成型，尺寸 5.2×5.4 mm
- 品牌：cjiang（长江微电）
三、性能要点与热管理
- DC偏置效应：随着直流偏置电流增加，电感值会下降，设计时应留有裕量。
- 损耗估算：在满载 4.5A 时，铜损约 I^2·R = 4.5^2 × 0.06 ≈ 1.22W，需注意温升与散热路径。
- 饱和特性：Isat=5A 表示在较大直流成分下仍能维持电感，但具体电感下降比和测量条件请以数据手册为准。
四、典型应用
- 同步/非同步降压转换器（DC-DC）
- 点位供电（POL）模块、母线滤波器
- LED 驱动、电源管理模块及工业控制电源
五、PCB 与焊接建议
- 使用厂方推荐的焊盘尺寸与焊接工艺，保证焊点完整与热流通道。
- 若工作电流靠近额定值，建议在焊盘下方或周围布置过孔并联通内层散热平面以降低温升。
- 推荐采用标准回流焊曲线（请参照元件资料），避免手工焊接反复加热。
六、选型与注意事项
- 运行电流应以额定电流为上限，若要求长期高可靠性和低温升，建议对额定电流进行降额（如70%~80%连续电流）。
- 若需更严格的电感精度、低 DCR 或高温特性，请对比同系列或其他型号并参考完整数据手册。
- 订购时确认封装尺寸、包装形式与批次，以便匹配自动贴装与生产需求。
如需我帮忙核对电感在特定工作点（如某输入/输出电压、开关频率和纹波电流下）的预计电感值、峰值电流损耗与温升估算，可提供工作条件，我可计算并给出具体建议。

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.
