FXL0650-220-M 产品概述

FXL0650-220-M 是长江微电(cjiang)推出的一款表面贴装功率型一体成型电感,额定电流 2.6A,电感值 22µH(±20%),饱和电流 Isat 3.5A,直流电阻(DCR)约 140mΩ,封装尺寸为 SMD 6.6 × 7.0 mm。该器件面向开关电源、功率滤波与电磁兼容抑制等需要中等电感值与较高直流电流承载能力的应用场景,具有体积小、结构稳固、适合集成化设计的特点。

一、主要参数概览

  • 型号:FXL0650-220-M
  • 品牌:cjiang(长江微电)
  • 类型:一体成型功率电感(SMD)
  • 尺寸:6.6 × 7.0 mm(表面贴装)
  • 电感值:22 µH ±20%
  • 额定电流(Irated):2.6 A
  • 饱和电流(Isat):3.5 A
  • 直流电阻(DCR):约 140 mΩ
  • 适用领域:DC-DC 转换器、输入/输出滤波、功率滤波及电流隔离等

二、性能特点与优势

  • 一体成型结构:机械强度高,抗振动性能优良,适合自动贴装与回流焊工艺,可靠性好。
  • 中等电感与较高承载电流:22µH 在许多降压/升压转换器的功率回路或滤波电路中能提供有效的能量存储与纹波抑制;2.6A 的额定电流适用于中等功率负载场景。
  • 较低 DCR:约 140mΩ 的直流电阻有助于降低铜损,提高效率,尤其在连续导通模式(CCM)应用中表现明显。
  • 饱和裕量:Isat 3.5A 表示在较高电流下仍能维持一定的磁性能,能在瞬态或冲击电流情况下保持稳定工作(具体饱和定义请参照厂方 Datasheet)。

三、典型应用场景

  • 开关电源(DC-DC)中作为能量储存元件或输出滤波电感
  • 电源输入滤波器与去耦,抑制输入电源纹波和高频干扰
  • 电动工具、便携设备、模块化电源等中等功率模块的功率回路
  • 电磁兼容(EMC)滤波单元,与陶瓷电容配合改善系统 EMI 性能
  • LED 驱动、电池管理模块(BMS)等对体积与电流承载有一定要求的应用

四、布局与焊接建议

  • 焊盘匹配:请按厂方推荐封装与焊盘尺寸设计 PCB,保证焊接可靠性与热传导性,避免焊盘过小导致焊点疲劳或虚焊。
  • 热管理:虽然本器件为一体成型,但在高电流应用中仍会产生热量。建议在器件下方和附近留有足够的铜厚与散热路径,必要时采用多层过孔(thermal vias)引导热量到内层或底层散热层。
  • 布局靠近电路:将电感放置在开关管和输出大电容之间的回路中,尽量缩短高 di/dt 路径的走线长度以降低 EMI 与寄生电感。
  • 回流焊工艺:兼容常见的无铅回流焊工艺。为避免应力与热损伤,建议遵循元件制造商的回流曲线与焊接温度限制。

五、选型与使用注意事项

  • 电感容差较宽:±20% 容差意味着电路设计需考虑电感变化对谐振频率、输出纹波和瞬态响应的影响,关键电路建议评估最差偏差下的性能。
  • 电流裕量和降额:额定电流 2.6A 为长期连续工作参考,Isat 3.5A 表示饱和点附近的极限值。建议在设计时留有一定降额空间以提高可靠性并降低温升。
  • 温升与效率:在高电流和高占空比条件下,DCR 产生的功耗(I^2·DCR)可能成为效率和温度上升的主要原因,应在热仿真和样机测试中验证温度分布。
  • 高频特性:作为功率电感,其交流特性(磁芯损耗、频响)会随频率变化,若用于高频开关环境,请参考详细频率特性曲线以评估损耗和效率。

六、采购与技术支持

  • 建议在批量采购前索取官方 Datasheet 和样品进行评估,并确认包装形式、出货期与质量认证(如需要 RoHS 等资料)。
  • 对于特殊环境(高温、汽车级、军工级)或关键可靠性要求,请与供应商/厂家沟通是否有符合相应等级的替代型号或测试报告。

总结:FXL0650-220-M 是一款面向中等功率应用的表面贴装一体成型电感,以 22µH 的电感值、较低 DCR 与可观的电流承载能力为设计者在 DC-DC 转换及滤波电路中提供可靠的电磁与热性能保障。定稿设计前,请结合厂方完整 Datasheet 与样品测试结果进行最终确认。

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
