FXL0630-470-M 产品概述

一、产品简介

FXL0630-470-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 47 µH(±20%)。该器件采用 SMD 封装,外形尺寸约 6.6 × 7.0 mm,针对中小功率开关电源和 EMI 抑制场景进行了优化设计。器件结构紧凑、机械强度好,适合自动贴装与回流焊工艺。

二、主要参数

  • 品牌:cjiang(长江微电)
  • 型号:FXL0630-470-M
  • 电感值:47 µH,公差 ±20%
  • 额定电流(Irated):1.5 A(连续)
  • 饱和电流(Isat):2 A(典型,磁性材料进入饱和时电感显著下降)
  • 直流电阻(DCR):约 385 mΩ
  • 类型:一体成型功率电感(封装式)
  • 封装:SMD,尺寸 6.6 × 7 mm

三、产品特点与优势

  • 体积小、磁芯封装一体化,便于高密度 PCB 布局。
  • 额定电流 1.5 A,可胜任小功率至中等功率的降压输出滤波与能量存储任务。
  • 饱和电流 2 A,短时允许过载能力较好,适合瞬态较大的负载环境。
  • 结构稳固、抗振动性能良好,适应自动化贴装和后续回流焊流程。
  • 适用于对成本和体积敏感、但对电感值要求中等的应用场景。

需要注意的是本型号 DCR 较大(≈385 mΩ),在较高直流电流下会产生明显的 I^2R 损耗和温升,设计时应权衡效率与体积/成本。

四、典型应用场景

  • 1–2 A 级别的降压(Buck)转换器输出电感。
  • 开关电源的输入/输出滤波与能量存储。
  • EMI 抑制网络和电源噪声滤波。
  • 工业控制设备、通信终端、便携式设备和 LED 驱动等对体积和成本敏感的电源模块。

五、使用建议与设计注意事项

  • 建议在连续工作电流下留有裕量(例如高于工作电流 15–30%),以降低温升与磁饱和风险。
  • 由于 DCR 较高,若系统对效率敏感(如电池供电、需控温),建议评估功耗并必要时选用低 DCR 的替代型号。
  • 请在最终设计中参考厂商提供的电感随直流偏置(L vs IDC)和温度特性曲线,以评估在工作点的实际电感值及损耗。
  • 若需符合特定可靠性或环境规范(如汽车级、AEC-Q、RoHS 等),请向厂家确认相关出厂认证与测试报告。

六、封装与贴装建议

  • FXL0630-470-M 为 SMD 封装,适配自动贴装与回流焊工艺。推荐在 PCB 布局时为其留足焊盘尺寸和热散路径,并在附近留出适当间距以利散热。
  • 回流焊参数请遵循供应商的焊接说明书;如无特殊说明,可采用行业通用回流曲线,但避免超过器件最大允许温度。
  • 储存与搬运时避免强烈冲击或弯曲应力,以防封装损伤或电性漂移。

七、质量与可靠性

长江微电为中小功率电感提供常规的出厂检验与电气参数测试。为保证长期稳定性,建议在设计验证阶段进行温升测试、湿热循环和振动测试,尤其是在高温或高湿环境下的应用场景。

备注:本文为产品概述与应用建议,具体电性能、L-Idc 曲线、温升与回流工艺参数请以厂家最新数据表为准。若需替代型号或更低 DCR/更高电流规格的建议,可提供系统工作点以便匹配。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
