FXL0518-4R7-M 产品概述
一、产品概述
FXL0518-4R7-M 是长江微电（cjiang）推出的一款一体成型功率电感，标称电感值为 4.7µH、允许误差 ±20%。该器件为表面贴装（SMD）封装，外形尺寸为 5.2 × 5.4 mm，专为开关电源和功率滤波电路设计，兼顾高电流能力与较小的占板面积。
二、主要性能参数
- 电感值：4.7 µH（±20%）
- 额定电流（Irated）：3.5 A
- 饱和电流（Isat）：4.0 A
- 直流电阻（DCR）：约 85 mΩ
- 封装形式：SMD，一体成型
- 外形尺寸：5.2 × 5.4 mm 品牌：cjiang（长江微电） 型号：FXL0518-4R7-M
三、性能特点与优势
该功率电感采用一体成型结构，具有良好的磁屏蔽性和机械强度，能在连续运行下提供稳定的电感值与低热损耗。较高的额定电流（3.5A）和较高的饱和电流（4A）使其适合中小功率电源回路。DCR 约 85 mΩ，在权衡电感值与损耗方面表现均衡，适合对效率与热管理有一定要求的应用。
四、应用场景
- DC-DC 降压/升压转换器（同步/非同步）
- 电源模块输入/输出滤波
- 汽车电子、工业控制、通讯设备的中功率电源
- 电池供电设备的能量滤波与去耦
五、布局与使用建议
为保证散热和电流承载能力，推荐接近热源或功率器件布置，并采用较短的电流回路走线以降低寄生阻抗。焊盘形状与推荐尺寸请参考厂家 PCB 布局建议，回流焊工艺应控制升温曲线以避免封装应力。若工作环境温度较高，需注意电流降额以避免饱和或过热。
六、选型与注意事项
在选型时，应综合考虑峰值电流、纹波电流、允许温升及系统效率需求。若电路有较大启动浪涌或瞬态电流，建议留有饱和裕量（Isat > 峰值电流）。对于对效率极为苛刻的设计，可考虑更低 DCR 或更大尺寸的替代型号。
七、质量与采购
FXL0518-4R7-M 由 cjiang（长江微电）生产，适配量产检测试验流程，支持常温电气测试与外观检验。采购时请确认批号与规格表（Datasheet），并在样品验证阶段测试实际电感、DCR 及在目标应用中的温升与饱和特性。若需更多技术资料或 PCB 推荐布局，请联系供应商索取 Datasheet 与应用笔记。

Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
