FXL0630-R47-M — 20A 功率一体成型电感 产品概述
一、概述
FXL0630-R47-M 为 cjiang（长江微电）推出的一款高电流 SMD 一体成型功率电感，标称电感值 470 nH，适用于要求高电流、低损耗和良好抗饱和特性的开关电源及电源滤波场合。器件采用模块化成型工艺，尺寸紧凑（6.6 × 7 mm），便于自动贴装与回流焊加工。
二、主要参数
- 电感值：470 nH（±20%）
- 额定电流：18 A（连续工作建议不超过此值）
- 饱和电流（Isat）：20 A（接近饱和时电感显著下降）
- 直流电阻（DCR）：约 4.1 mΩ（低 DCR 有利于降低铜损）
- 封装形式：SMD 一体成型，尺寸 6.6 × 7 mm
- 品牌：cjiang（长江微电）
三、产品特点
- 高电流承载：额定 18 A，短时可承受至 20 A 的饱和极限，适合大电流点对点电源应用。
- 低直流电阻：4.1 mΩ 的低 DCR 有效减少导通损耗，提升转换效率与热稳定性。
- 抗饱和设计：成型磁芯与绕制工艺优化，在高直流偏置下仍能维持较好的电感保持率。
- 封装可靠：一体成型结构增强机械强度与抗振性，适合自动化生产与复杂环境使用。
四、典型应用
- 同步降压（buck）转换器和点对点电源模块（POL）
- 服务器、通信设备与电信电源滤波器
- LED 驱动和电池供电系统的电源管理
- 工业与汽车电子（非声称车规级产品前请确认额外可靠性要求）
五、使用建议与注意事项
- 电感随直流偏置电流下降明显，设计时应以额定电流 18 A 为长期工作上限，并留有裕量以避免过早进入饱和区。
- 散热：在高电流应用中建议增大焊盘铜厚、使用多孔过孔导通底层铜箔或散热铜箔，以降低温升。
- PCB 布局：输入/输出回路尽量缩短环路、增大充裕铜面积并靠近电感布置以减少寄生阻抗与 EMI。
- 制程：推荐采用标准无铅回流焊工艺，遵循器件供应商的回流温度曲线以确保可靠焊接。
六、封装与可靠性
FXL0630-R47-M 封装紧凑、适配表面贴装工艺，成型封装提高了机械与环境适应性。对于关键或高可靠性项目，建议与供应商确认温度循环、湿热以及振动寿命等试验结果，并在实际应用中完成必要的验证测试。
七、总结
FXL0630-R47-M 以其 470 nH、电流能力 18–20 A 的组合，适合在大电流 DC-DC 变换与电源滤波场景中替代传统线绕电感，兼顾低损耗与良好机械可靠性。设计时应注意电流裕量与散热管理，以发挥器件最佳性能。如需更详细的频率响应、温升曲线或封装图纸，请联系供应商获取完整数据手册与样品验证资料。

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.
