FXL0630-4R7-M 产品概述

一、产品简介

FXL0630-4R7-M 是长江微电(cjiang)推出的一体成型功率电感,标称电感值 4.7µH,公差 ±20%,额定电流 6A,饱和电流(Isat)9A,直流电阻(DCR)约 33mΩ。封装为 SMD,尺寸 6.6×7.0 mm,结构为一体成型(molded)设计,适合表面贴装自动化生产与高密度电源模块应用。

主要参数:

  • 电感值:4.7 µH(±20%)
  • 额定电流:6 A
  • 饱和电流(Isat):9 A
  • 直流电阻:33 mΩ
  • 封装尺寸:6.6 × 7.0 mm(SMD)
  • 类型:一体成型功率电感

二、主要特性

  • 高电流承载能力:6A 连续工作,短时冲击可达 9A,适用于中高电流开关电源。
  • 低直流电阻:33mΩ 有利于降低传导损耗,提升转换效率。
  • 一体成型结构:机械强度高,抗振动性好,适合工业和汽车类环境(需按具体认证确认)。
  • 小尺寸设计:6.6×7 mm 封装兼顾功率与占板面积,便于模块化设计与高密度布局。

三、电气性能与选型建议

  • 额定电流与功耗:在额定电流 6A 下,近似铜损 P = I^2·DCR ≈ 6^2×0.033 ≈ 1.19 W,设计时应考虑散热与温升。长期工作建议留有余量,避免持续在接近 Isat 区域运行。
  • 饱和特性:当电流接近或超过 Isat(9A)时,电感量会显著下降,可能导致输出纹波和控制环路不稳定。选型时应以最大工作电流远低于 Isat 为宜。
  • 辅助参数:考虑开关频率、纹波电流与电流波形对有效电感值的影响,必要时联系厂商获取频率特性与热阻数据。

四、封装与 PCB 布局建议

  • 布局:将电感尽量靠近功率开关器件(MOSFET/同步整流器)和输出电容,缩短信号环路以降低 EMI。
  • 走线:使用宽厚铜箔或多层过孔(thermal vias)以降低寄生电阻并利于散热。
  • 固定与回流焊:遵循焊膏与回流曲线规范,避免过热或机械应力集中;一体成型封装对焊接可靠性友好,但需按厂家回流参数操作。

五、典型应用

  • 同步降压(Buck)转换器的输出滤波电感
  • 工业电源模块、电动设备驱动电源
  • 通信、服务器电源和消费类电子的功率管理
  • 电池供电系统与充电器等需中高电流滤波场合

六、选购与可靠性注意事项

  • 工作温度与热容:在高温环境下 DCR 上升、额定电流需降额,设计时留有温升裕量。
  • 测试与验证:在最终系统中进行热成像、长时间老化测试及电感饱和测试,以确认在典型负载下的性能。
  • 物料一致性:批次间参数可能存在小幅波动(尤其在 ±20% 公差下),大批量项目建议冻结首批样品并建立来料检验标准。

总结:FXL0630-4R7-M 以紧凑封装和良好电流承载能力为特点,适合要求中高电流、占板面积受限的电源设计场景。合理的选型与 PCB 热管理能充分发挥其效率与可靠性优势。如需更详细的频率特性、热阻及寿命数据,可向长江微电索取完整规格书。

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
