FXL0650-3R3-M — 3.3µH 一体成型功率电感 产品概述

一、产品简介

FXL0650-3R3-M 是长江微电(cjiang)出品的一款表面贴装功率电感,额定电流 8.5A,饱和电流(Isat)10A,标称电感值 3.3µH,容差 ±20%。产品为一体成型(molded)结构,外形尺寸 7.0 × 6.6 × 4.8 mm(SMD),直流电阻(DCR)约 22 mΩ,适用于中高电流密度的开关电源与电源模块场合。

二、主要规格(关键参数)

  • 品牌:cjiang(长江微电)
  • 型号:FXL0650-3R3-M
  • 电感值:3.3 µH ±20%
  • 额定电流(Irated):8.5 A(在规定温升和环境条件下的连续载流能力)
  • 饱和电流(Isat):10 A(电感明显降值时的参考点)
  • 直流电阻(DCR):22 mΩ(典型)
  • 封装与尺寸:SMD,7.0 × 6.6 × 4.8 mm
  • 结构类型:一体成型(高可靠性、良好机械强度)

三、产品特点与优势

  • 高电流能力:额定 8.5A、饱和 10A,适合大电流输出的降压型(buck)转换器与电源滤波。
  • 低 DCR:约 22 mΩ,降低导通损耗,提高效率,适合要求较高转换效率的应用。
  • 一体成型封装:结构稳固、耐振动、适合自动贴装与回流焊工艺,便于大批量生产。
  • 紧凑体积:7×6.6×4.8 mm 小尺寸,有利于PCB面积受限的设计。
  • 通用兼容:适用于多种开关频率和拓扑,只需在电路中配合合适的电容和磁芯损耗考虑即可。

四、典型应用场景

  • DC-DC 降压(Buck)转换器、同步整流电源模块
  • 电源管理模块(PMIC)和多相电源电路
  • 汽车电子、工业电源、通信设备电源前端
  • LED 驱动与电池供电系统(大电流输出)
  • 电脑周边与存储设备的电源滤波

五、使用与设计建议

  • 电流余量与降额:为了控制温升与确保长期可靠性,建议连续工作电流按额定电流的 70%–85% 选型,即优先考虑 ≤8.5A 的适度余量。峰值或短时脉冲可接近或达到 Isat,但应避免长时间处于饱和区域。
  • 布局要点:将电感与开关器件、输入/输出电容尽量靠近,缩小开关回路面积;引脚与走线尽量加宽、短化以降低寄生电阻与发热。需要时采用多过孔(vias)加大散热通道。
  • 温升与散热:功率损耗主要来自 DCR 与磁芯损耗,注意实际工作频率、纹波电流对温升的影响。若应用在高环境温度或高频下,应评估热阻并做好热管理。
  • 焊接工艺:支持常规回流焊(遵循无铅回流曲线),为保证焊接质量与性能稳定,请遵循厂商推荐的回流温度曲线与PCB清洗流程。
  • 饱和与磁芯损耗:Isat 为电感进入饱和的参考值,接近或超过该电流时电感值会显著下降,可能影响环路稳定性和输出纹波,应在设计中避免长期运行在饱和区。

六、封装与采购注意

  • 封装尺寸:7.0 × 6.6 × 4.8 mm(SMD)——实际贴装时请参考厂商提供的尺寸图和焊盘推荐,确保焊点可靠与良好散热。
  • 型号与品牌:FXL0650-3R3-M,品牌 cjiang(长江微电)。采购时请核对完整型号与规格书,确认供货批次和包装形式(卷装/盘装)以满足生产需要。
  • 替代与比较:在需更低损耗或更小尺寸时,可比较其他同类 3.3µH 功率电感的 DCR、Isat 与散热性能,选择最符合系统效率与尺寸约束的器件。

七、总结

FXL0650-3R3-M 为一款面向中高电流应用的紧凑型一体成型功率电感,具有较低 DCR 与良好饱和电流特性,适合用于开关电源与电源滤波场合。在实际设计中,合理的电流降额、良好的 PCB 布局与热管理是发挥该器件性能与保证长期可靠性的关键。欲获得更详细的电磁特性曲线、焊接规范与机械图纸,请参阅长江微电官方数据手册或直接联系供应商。

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
