FNR6028S220MT 产品概述

一、产品概述

FNR6028S220MT 是长江微电(cjiang)推出的一款 SMD 功率电感,采用磁胶屏蔽结构,封装尺寸为 6×6 mm。标称电感值为 22 µH,公差 ±20%,面向开关电源滤波、电流滤波与能量储存等功率应用场景设计。器件体积小、安装方便,适用于对体积与性能有均衡要求的中小功率电源系统。

二、主要参数

  • 电感值:22 µH(±20%)
  • 额定电流:1.6 A(连续工作电流)
  • 饱和电流(Isat):1.8 A(电感下降到规定比例时)
  • 直流电阻(DCR):约 182 mΩ
  • 类型:磁胶屏蔽电感(屏蔽式功率电感)
  • 封装:SMD,尺寸 6 mm × 6 mm
  • 品牌:cjiang(长江微电)

三、核心特性

  • 高磁通容忍度:Isat 达到 1.8 A,能在短时冲击或峰值电流场景中保持稳定工作,不易饱和。
  • 低 DCR:182 mΩ 的直流电阻在其电流等级下提供较低的功率损耗,有利于提高转换效率并降低发热。
  • 屏蔽结构:磁胶屏蔽设计有效降低辐射磁场和互扰,便于与其他敏感元件共存,提高系统抗干扰能力。
  • SMD 组装:6×6 mm 的表贴封装适合自动贴片及回流焊工艺,利于产业化生产与成本控制。

四、典型应用

  • DC-DC 降压/升压转换器中的输出滤波或能量储存元件
  • 电源管理模块(PMIC)辅助电感
  • 工业控制、汽车电子(建议参照汽车级规范)及消费电子的电源滤波/去耦场合
  • EMI 抑制与开关节点滤波

五、使用与布局建议

  • 布局:将电感靠近开关管或稳压芯片的开关节点放置,缩短高频回路环路面积,以减少辐射和寄生感抗。
  • 散热与电流容限:在接近额定电流工作时注意 PCB 散热路径,合理加大铜箔以降低温升。
  • 焊接:遵循厂家推荐的回流温度曲线和焊盘尺寸,避免过度热循环导致机械应力或黏结失效。
  • 退耦与滤波:与输入/输出电容配合使用时注意电流谐波与容性负载引起的谐振,必要时加阻尼网络。

六、选型与可靠性注意事项

  • 电流裕量:在实际设计中建议以额定电流 1.6 A 为长期工作基准,为保证可靠性和降低温升,应预留 20% 以上余量或根据工作温度进行降额处理。
  • 饱和评价:若系统存在较大瞬时电流脉冲,应重点验证在脉冲条件下的电感下降与热性能,防止达不到预期的储能能力。
  • 温度与寿命:产品在高温或频繁热循环环境中性能会受到影响,关键应用建议与厂方确认温度等级与寿命测试数据。
  • 替代与兼容:选型时注意电感值、公差、DCR 与饱和电流的匹配,屏蔽形式与封装尺寸也会影响最终电磁兼容性能。

七、总结

FNR6028S220MT 以 22 µH 的电感值、1.6 A 的额定电流和 1.8 A 的饱和电流,结合磁胶屏蔽与 6×6 mm 的 SMD 封装,为中小功率电源设计提供了一种体积与性能均衡的选择。适用于需要屏蔽、稳定工作与自动化组装的场景。选用时应重点关注工作电流裕量、热管理与电磁兼容设计,以确保长期可靠运行。若需更详细的电气特性曲线或封装图纸,建议联系长江微电获取完整数据手册与推荐焊盘。

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
