FXL0624-4R7-M — 一体成型功率电感产品概述
一、主要规格概览
- 品牌：cjiang（长江微电）
- 型号：FXL0624-4R7-M
- 电感值：4.7 μH（±20%）
- 额定电流：5 A
- 饱和电流（Isat）：7.5 A（规格点指示磁芯开始明显降磁）
- 直流电阻（DCR）：50 mΩ
- 封装：SMD，一体成型，尺寸约 6.6 × 7 mm
二、主要特性
- 一体成型结构，机械强度高，适合波峰/回流焊自动化生产。
- 低成本功率电感，强调大电流承载能力与体积比。
- DCR 50 mΩ 表明对大电流环境有一定损耗，需关注温升与散热设计。
- ±20% 容差适用于电源滤波与能量储存场景，对精密滤波要求较低。
三、典型应用场景
- DC-DC 降压转换器（buck）输出滤波或能量储存。
- 电源管理模块、车载电子电源、工业控制电源。
- LED 驱动、电机驱动前端滤波与输入整流滤波。
四、电气与热特性说明
- 在额定电流 5 A 下，功耗约 P = I^2·DCR = 25 × 0.05 ≈ 1.25 W，需评估器件及周边温升。
- 饱和电流 7.5 A 为磁芯开始明显降感的参考值，连续工作建议以额定电流为上限并留有余量。
- 对于高占空比或高纹波电流的场合，应计算峰值磁通与电感降额，避免进入饱和区导致感值急剧下降。
五、PCB 布局与安装建议
- 两端电流回路应尽量短、宽，降低串联寄生电阻与电感。
- 器件附近添加散热铜箔或多层铜通孔以改善热传导。
- 对于高频开关电源，输入输出电容应靠近器件和开关管布局，减小环路面积。
- 建议按供应商数据手册提供的焊盘尺寸与回流温度曲线进行焊接。
六、可靠性与焊接工艺
- 适用于常规回流焊工艺；焊接温度曲线请参考原厂规范以避免过热导致焊点或封装损伤。
- 对于长期高电流工作，需评估振动、热循环及长期热阻变化对 DCR 和感值的影响。
七、选型要点与注意事项
- 若要求更低损耗或更低 DCR，应考虑更大截面铜线或不同材料的电感型号。
- 设计时建议遵循电流裕量原则：连续工作电流不宜长期接近 Isat，以保证感值稳定与温升可控。
- 在关键应用（如车规、医疗）前应确认完整规格书及环境/认证信息。
八、订购信息与技术支持
- 型号：FXL0624-4R7-M，品牌：cjiang（长江微电），通常以卷带（Tape & Reel）方式供应。
- 采购与大批量使用前建议向厂家索取完整数据手册、纹波电流曲线、温升曲线及可靠性测试报告。
如需更详细的 PCB 焊盘建议、频率响应或基于具体电源拓扑的选型计算，可提供电路参数以便给出更精确的工程建议。

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.
