FNR3010S100MT 磁胶屏蔽功率电感产品概述

一、产品基本定位与命名解析

FNR3010S100MT是长江微电(Cjiang)推出的小型化低电流磁胶屏蔽功率电感,核心面向紧凑空间的电源管理场景。其命名遵循行业通用逻辑:

  • FNR:长江微电功率电感系列标识;
  • 3010:封装尺寸(平面3mm×3mm,厚度10mm);
  • S:屏蔽型(磁胶包裹磁芯,抑制漏磁);
  • 100:电感值(10μH,即100×0.1μH);
  • MT:磁胶类材料工艺标识。

该产品为贴片式(SMD)器件,适配自动化贴装产线,适合中小批量至大规模量产。

二、核心电性能参数详解

电性能直接决定电源电路稳定性,关键参数及实际意义如下:

  1. 电感值与精度:10μH±20%,满足高频DC-DC转换器的储能需求,精度范围适配多数消费电子/物联网设备的电源设计;
  2. 额定电流(Irms):700mA(25℃环境下),指连续工作时不超过允许温升(≤40℃)的最大电流——超过此值会导致电感发热加剧,缩短寿命;
  3. 饱和电流(Isat):750mA,指磁芯饱和时(电感值下降至初始值的80%)的临界电流——设计时需确保工作电流≤600mA(Isat的80%),避免电感值骤降导致输出电压不稳定;
  4. 直流电阻(DCR):520mΩ,低DCR可降低电流功耗(700mA时功耗≈0.25W),减少发热,提升电路效率;
  5. 屏蔽特性:磁胶屏蔽结构,漏磁抑制率达90%以上,可降低对周边敏感元件(如射频模块)的电磁干扰,同时提高自身抗干扰能力。

三、结构与封装特性

  1. 小型化封装:3mm×3mm×10mm的贴片封装,平面尺寸仅为常见0805封装的1.5倍左右,适配智能手机、可穿戴设备等紧凑空间;
  2. 磁胶屏蔽结构:采用磁胶包裹铁氧体磁芯,相比裸磁芯电感,不仅漏磁更低,还能减少磁芯机械振动(降低电路噪音);
  3. 贴装兼容性:符合IPC标准的焊盘尺寸,适配回流焊、波峰焊工艺,贴装良率≥99.5%,适合大规模量产。

四、典型应用场景

该产品针对低电流、小尺寸需求设计,核心应用场景包括:

  1. 消费电子:智能手机、平板电脑的DC-DC降压模块(如将4.2V电池电压转换为1.2V/1.8V供CPU使用);
  2. 可穿戴设备:智能手表、运动手环的充电管理电路与电源转换模块(适配10mm厚度的设备空间);
  3. 物联网设备:低功耗WiFi/蓝牙模块的电源电路(工作电流通常≤500mA,符合额定电流要求);
  4. 小型工业控制:微型PLC、传感器节点的辅助电源模块(满足-40℃~+85℃的宽温需求)。

五、品牌与可靠性保障

长江微电作为国内电感行业主流供应商,FNR3010S100MT具备以下可靠性优势:

  1. 品质管控:通过ISO9001、IATF16949认证,产品经过高低温循环(-40℃~+85℃,1000次)、湿度测试(85℃/85%RH,500h)、振动测试(10-2000Hz,加速度2g);
  2. 环保合规:符合RoHS 2.0、REACH等标准,无铅无卤,适合出口市场;
  3. 供应链稳定:年产能达千万级,可满足中小批量至大规模量产需求,交期通常为1-2周。

该产品以小尺寸、低损耗、抗干扰为核心优势,是消费电子、物联网等领域低电流电源设计的优选器件。

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
