FXL0630-R68-M — 17A 一体成型功率电感(680nH ±20%)

一、产品概述

FXL0630-R68-M 是长江微电(cjiang)推出的一款表面贴装功率电感,标称电感值为 680 nH,公差为 ±20%。该器件为一体成型(molded)结构,尺寸约为 6.6 × 7 mm,专为高电流、低损耗的开关电源与功率模块设计。额定电流为 16 A,饱和电流(Isat)17 A,直流电阻(DCR)仅 5.3 mΩ,适合要求高效率与高电流承载的场合。

二、主要电气参数与特性

  • 电感值:680 nH ±20%
  • 额定电流:16 A
  • 饱和电流(Isat):17 A(通常定义为电感下降至初始值的某一百分比,详情参考厂方测量标准)
  • 直流电阻(DCR):5.3 mΩ(典型值,低 DCR 有利于减小 I²R 损耗)
  • 封装形式:SMD,一体成型
  • 尺寸:约 6.6 × 7 mm
  • 品牌:cjiang(长江微电)

这些参数使本型号在高电流密度应用中能保持较小能量损耗与较低温升,同时在开关瞬态下具备良好抗饱和能力。

三、性能优势

  • 低 DCR:5.3 mΩ 的直流电阻可显著降低导通损耗,提高系统效率,尤其适用于高电流路径。
  • 高额定/饱和电流:16 A / 17 A 的电流等级保证在大电流工作时仍有足够余量,避免在临时过载或启动冲击时发生磁饱和。
  • 一体成型结构:机械强度高,适应波峰或回流焊高温工艺;封装紧凑,便于自动化贴片生产。
  • 体积与功率密度平衡:6.6×7 mm 级别在占板空间与散热能力之间取得良好折中,利于高功率密度电源设计。

四、典型应用场景

  • 同步降压(Buck)和升压(Boost)DC-DC 转换器
  • 服务器与通信设备的电源模块(VRM、POL)
  • 电动工具、无人机等电源管理
  • LED 驱动、电池管理系统(BMS)
  • 工业控制与汽车电子(需根据实际认证与温度评级确认)

五、使用建议与电路布局要点

  • 布局:电感应尽量靠近开关 MOSFET 与电容,缩短高频回路环路面积;输入/输出走宽铜皮并多过孔过底层以利散热。
  • 散热:高电流工作会造成温升,建议评估实际工况下的温度升高并留有电流余量,必要时采用散热铜箔或散热片。
  • 饱和与纹波电流:选择器件时应考虑交流纹波电流及峰值电流,保证在最大纹波与过载时电感不会进入不利饱和区。
  • 焊接:遵循无铅回流温度曲线的通用建议,避免超出制造商给出的最大温度与时间限制;回流后建议进行目视与电性能抽检。

六、选型与注意事项

  • 温度与频率依赖:电感值、损耗与饱和特性会随温度与直流偏置电流变化,设计时请参考厂方完整数据表与频率特性曲线。
  • 封装机械约束:安装时注意不要在器件上施加过大机械力,以免造成内部线圈或封装裂纹。
  • 可靠性与认证:若用于汽车或工业严苛环境,请向供应商确认相关认证(如AEC-Q 或更高等级)与长期可靠性试验数据。
  • 备货与替代:在量产前建议进行样品评估并与供应商确认交期、最小起订量与替代型号(若需要不同电感值或更高温度等级)。

如需更详细的频率特性曲线、热阻数据、典型电路测试波形或封装尺寸图(PCB footprint),建议向长江微电获取 FXL0630-R68-M 的完整产品数据手册与机械图纸,以便在实际电源设计中做精确仿真与布局优化。

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
