FNR4018S1R5MT 产品概述

一、产品简介

FNR4018S1R5MT 是长江微电(cjiang)推出的一款表面贴装功率电感,额定电流3.2A,饱和电流4A,标称电感值1.5uH(±20%)。器件采用磁胶屏蔽结构,尺寸约4×4mm,适用于中小功率开关电源和电源滤波场合,兼顾高电流承载与较低电阻损耗。

二、主要电气参数

  • 电感值:1.5 µH,公差 ±20%
  • 额定电流(Ir):3.2 A(连续)
  • 饱和电流(Isat):4 A(典型)
  • 直流电阻(DCR):约 39 mΩ
  • 类型:磁胶屏蔽电感(功率电感,SMD)

三、结构与封装特点

磁胶屏蔽设计有效抑制外泄磁场,减少对邻近元件的干扰;SMD 封装便于自动化贴装,尺寸小巧(4×4mm)有利于高密度布局。线圈与磁芯采用优化工艺以兼顾饱和性能与温升控制。

四、典型应用场景

  • 同步降压/升压转换器的储能电感
  • DC-DC 模块输出滤波与纹波抑制
  • 通信设备、工控与车载电子中小功率电源
  • 高密度电源管理板卡

五、选型与使用建议

为确保长期可靠性,建议在设计中对电感进行电流余量考虑:连续工况下尽量让实际工作电流低于额定电流(留有热余量);避免长期接近饱和电流以免电感量下降。推荐将电感置于靠近开关管与电容的位置,减小走线环路面积;为改善散热可在封装下方增加过孔或铜箔散热路径。并配合低ESR输出电容与合理的布局布线,以获得最佳转换效率和低纹波。

六、采购与质量提示

选购时请确认型号与封装一致并索取样片及规格书(Datasheet)进行温升与电流下的测试验证。同时关注供应方的批次一致性与可靠性认证,便于在量产中保持性能稳定。

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
