FNR5040S8R2MT 产品概述

一、产品简介

FNR5040S8R2MT 是长江微电(cjiang)推出的一款表面贴装(SMD)磁胶屏蔽功率电感,外形尺寸约为5×5mm,额定用于中小功率开关电源滤波与储能。该器件以高电流承载和较低直流电阻为特点,适合在空间受限的电源模块中替代传统钳位和绕线电感。

二、主要规格

  • 电感值:8.2 μH,公差 ±20%
  • 额定电流(Ir):2.6 A(温升与环境有关)
  • 饱和电流(Isat):2.9 A(磁性材料开始饱和时测得)
  • 直流电阻(DCR):约 62 mΩ
  • 类型:磁胶屏蔽电感(shielded)
  • 封装:SMD,尺寸 5×5 mm

三、性能特性

该电感采用磁胶材料与屏蔽结构,降低了磁通外泄与电磁干扰(EMI)。较低的 DCR 有利于降低功耗与温升,提高转换效率。Isat 值表明在接近 3 A 的瞬态或脉冲条件下仍能维持一定的电感量,适合脉冲电流较大的开关节点。

四、典型应用

适用于降压(buck)、升压(boost)等开关稳压器的输出或能量存储环节;移动设备、工控电源、车载电子(非关键安全回路)、LED 驱动与通信设备的电源模块等场景。

五、封装与焊接

器件为 SMD 封装,推荐采用无铅回流焊工艺,回流曲线应参考厂商温度资料以避免过热导致磁性材料退磁或塑封件变形。PCB 焊盘布局应保证良好焊点和散热路径,焊盘尺寸与过孔设计按厂商封装图进行。

六、使用建议与注意事项

  • 在设计中应留有电流裕度,长期工作建议按额定电流以下运行以延长寿命。
  • 注意环境温度对电感值与饱和电流的影响,高温会降低额定电流能力。
  • 高频滤波时考虑电感频率响应和自谐频率,必要时与电容网络配合优化环路。
  • 存储避免高温潮湿,搬运时防止机械冲击或跌落。

七、样品与采购信息

标称型号 FNR5040S8R2MT,品牌 cjiang(长江微电)。批量采购前建议索取样品并在目标电路中做功耗、温升及电磁兼容测试,确认满足系统需求后再进行量产订购。若需详细封装图、回流曲线或电感频率特性,请联系供应商或查阅产品数据手册。

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
