FXL0530-3R3-M 产品概述

一、产品简介

FXL0530-3R3-M 是长江微电(cjiang)推出的一款一体成型功率电感,标称电感量为 3.3 μH,公差 ±20%。器件为贴片封装(SMD),外形尺寸 5.2 × 5.4 mm,专为开关电源与点(POL)电源模块等高电流场合设计。额定电流 5.5 A,饱和电流(Isat)6 A,直流电阻(DCR)约 38 mΩ,适合中高电流、低损耗滤波与储能应用。

二、主要参数(关键信息)

  • 型号:FXL0530-3R3-M
  • 品牌:cjiang(长江微电)
  • 电感值:3.3 μH ±20%
  • 额定电流:5.5 A
  • 饱和电流(Isat):6 A
  • 直流电阻(DCR):38 mΩ(典型)
  • 封装:SMD,尺寸 5.2 × 5.4 mm
  • 类型:一体成型功率电感

三、产品特性与优势

  • 高电流承载:5.5 A 的额定电流与 6 A 的饱和电流为开关稳压器提供充足的储能与电流通道,能承受较大的纹波电流与瞬态冲击。
  • 低 DCR 损耗:38 mΩ 的低直流电阻有助于降低铜损和温升,提升转换效率。
  • 一体成型结构:机械强度高,适配自动贴装与回流焊工艺,可靠性好。
  • 紧凑封装:5.2 × 5.4 mm 的体积在保证电感量的同时节约 PCB 面积,利于模块化设计。

四、典型应用场景

  • DC–DC 降压(Buck)转换器、电源模块(POL)
  • 移动电源、车载电源与通信设备的输入/输出滤波
  • LED 驱动、电机驱动中的电流储能与滤波
  • 对 EMI/噪声抑制有要求的电源前端滤波

五、选型与使用建议

  • 电流裕量:建议在稳态工况下工作电流不超过额定电流的 80% 左右,峰值或短时冲击应低于 Isat,以避免电感饱和导致工作点失稳。
  • 损耗考虑:在高频或高纹波电流下,应重点关注 DCR 引起的铜损与温升,根据系统允许的温升选择合适散热措施。
  • 封装与布局:紧靠开关器件与输入/输出电容布局,缩短电感与电容之间回路长度以减小寄生电感与 EMI。
  • 焊接工艺:建议采用推荐回流曲线焊接,避免超温或过长加热时间导致性能退化。

六、可靠性与测试要点

  • 建议进行实际系统环境下的温升测试与长期老化验证,关注在最大纹波电流与环境温度下的电感变化与 DCR 上升。
  • 对于汽车或工业级应用,应与供应商确认温度范围、机械振动与湿热可靠性数据及相关认证信息。

FXL0530-3R3-M 以其高电流能力、低 DCR 与小型化封装,适合在对效率、体积和可靠性有较高要求的电源设计中使用。在最终设计中请结合实际工作电流、纹波以及热环境进行验证,以确保长期稳定运行。

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
