FNR4030S1R5MT 磁胶屏蔽功率电感产品概述

一、产品基本定位与品牌背景

FNR4030S1R5MT是长江微电(cjiang) 推出的一款中小功率磁胶屏蔽贴片电感,主打小型化、低EMI(电磁干扰)与高效能,适配消费电子、小型工业设备的电源管理场景。长江微电作为国内电感领域的成熟厂商,该产品延续了品牌对可靠性、性价比的追求,工艺稳定性经批量验证,适合中低端至中端电子设备的电源设计需求。

二、核心参数与性能指标

产品参数直接决定应用边界,关键指标及意义如下:

  • 电感值:1.5μH ±20%,覆盖DC-DC转换、滤波电路的常规储能需求,精度满足大多数电源设计的误差要求(无需额外高精度补偿);
  • 电流能力:
    • 额定电流(Irms)3.6A:连续工作时电感温升不超规格(通常≤40℃),保证长期稳定;
    • 饱和电流(Isat)5.3A:电感值下降30%时的峰值耐受电流,可应对短暂负载波动;
  • 直流电阻(DCR):26mΩ,低电阻设计减少铜损(功率损耗=I²×DCR),提升电源转换效率,降低设备发热;
  • 屏蔽类型:磁胶屏蔽,通过磁胶包裹磁芯抑制漏磁,减少对周边射频电路(WiFi、蓝牙)的干扰;
  • 封装尺寸:SMD 4030(实测4mm×4mm×3mm),贴片式适配自动化生产,支持PCB高密度布局。

三、结构设计与工艺特点

  1. 磁胶屏蔽结构:区别于传统金属屏蔽,磁胶包裹铁氧体磁芯更轻薄,漏磁抑制更均匀,EMI性能优于普通非屏蔽电感;
  2. 绕组工艺:采用高导电率铜线绕制,优化绕线密度,在保证电感值的同时控制DCR,平衡储能与损耗;
  3. 封装可靠性:SMD封装符合回流焊规范(支持260℃峰值温度),焊接后机械强度可靠,适应-40℃至+125℃宽温环境;
  4. 磁芯材料:低损耗铁氧体磁芯,减少磁损(磁芯发热),进一步降低整体功率损耗。

四、典型应用场景

结合参数特性,该产品适配以下场景:

  • 消费电子:智能手机/平板的CPU/GPU降压电路、智能音箱/路由器的电源滤波、TWS耳机充电盒的电源管理;
  • 小型工业:小型PLC、传感器节点、工业遥控器的电源单元,低功率电机驱动的滤波;
  • 智能家居:智能门锁、智能灯光控制器的电源转换模块;
  • 车载低功率:行车记录仪、车载充电器的电源电路(需确认符合车载温湿度标准)。

五、产品优势与市场价值

  1. 低EMI适配敏感设备:磁胶屏蔽有效降低电磁辐射,避免干扰射频模块,适合对EMI要求严格的消费电子;
  2. 小型化降本:4×4mm封装缩小PCB占用面积,适配设备轻薄化趋势,同时减少PCB布线成本;
  3. 高效能省功耗:26mΩ低DCR可降低约1.5%的电源损耗,减少设备发热,延长电池续航(针对便携设备);
  4. 性价比突出:长江微电的成熟工艺保证供货稳定,成本控制合理,适合批量应用(如中低端智能手机量产)。

六、选型与使用注意事项

  1. 电流匹配:连续工作电流≤3.6A,峰值电流≤5.3A(超饱和会导致电感值骤降,影响电路稳压);
  2. 精度需求:±20%精度满足常规设计,若需±10%高精度(如医疗设备),需选同系列其他型号;
  3. 焊接规范:遵循IPC-A-610标准,避免多次回流焊(≤2次),防止磁芯性能衰减;
  4. 环境规避:远离强磁场(如扬声器、电机),避免磁芯饱和或性能漂移。

该产品凭借平衡的参数与成本优势,成为中小功率电源设计的高性价比选择,尤其适合对EMI、小型化有要求的批量应用场景。

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
