FNR3015S151MT 磁胶屏蔽功率电感产品概述

一、产品基本定位

FNR3015S151MT是长江微电(cjiang)推出的SMD磁胶屏蔽功率电感,针对紧凑空间、低功耗场景设计,属于微型封装电感系列。型号命名遵循行业规则:FNR为系列标识,3015对应封装尺寸(长×宽×高:3.0mm×3.0mm×1.5mm),151表示电感值150μH(15×10¹μH),MT为磁胶屏蔽工艺标识。该产品兼具低EMI(电磁干扰)与高稳定性,是便携式设备、小型通信模块的核心电感方案。

二、核心电气参数解析

需结合应用场景重点关注以下参数,避免选型偏差:

  1. 电感值与精度:150μH±20%,满足常规储能/滤波需求(精度范围适用于电源纹波抑制、DC-DC输出滤波等场景;若需高精度滤波,需选择±10%型号);
  2. 电流特性:
    • 额定电流(I_rms)230mA:工作电流不超过此值时,电感值变化率<10%,保证电路性能稳定;
    • 饱和电流(I_sat)220mA:电流超过此值时,磁芯饱和导致电感值骤降(如降至原值的50%以下),直接影响DC-DC转换效率;
  3. 直流电阻(DCR):4.94Ω,反映绕组铜损,小电流(<200mA)下铜损可忽略,适合低功耗电路;
  4. 屏蔽特性:磁胶屏蔽结构,相比非屏蔽电感EMI辐射降低约30%,可减少对射频模块、传感器等敏感元件的干扰。

三、封装与物理特性

  1. 封装形式:SMD(表面贴装),适配回流焊工艺,焊接可靠性符合IPC-A-610标准;
  2. 尺寸规格:3.0mm×3.0mm×1.5mm(微型封装),可节省PCB空间60%以上,适配高密度电路布局(如智能手环、蓝牙模块);
  3. 工作温度范围:-40℃+125℃(典型值),满足工业级(-40+85℃)与消费级(0~+70℃)设备的温度要求;
  4. 材料特性:铁氧体磁芯+漆包铜线绕组,磁胶屏蔽层耐温性好,长期工作无老化、脱落问题。

四、典型应用场景

结合参数特点,该电感主要应用于:

  1. 低功耗DC-DC转换器:如智能手环、蓝牙耳机的5V转3.3V/1.8V降压电路(输出电流<200mA),电感值稳定,纹波抑制效果佳;
  2. 小型无线通信模块:蓝牙5.0、WiFi 4、LoRa等低功耗模块的电源滤波电路,磁胶屏蔽减少射频干扰,提升通信稳定性;
  3. 小功率LED驱动:微型LED背光源、指示灯的恒流驱动电路,电感储能满足小电流LED(<100mA)的工作需求;
  4. 物联网终端:传感器节点、智能穿戴设备的电源管理单元,紧凑封装适配设备小型化设计。

五、选型与使用注意事项

  1. 电流余量控制:实际工作电流需低于额定电流230mA,峰值电流不超过饱和电流220mA(避免磁芯饱和导致电路效率下降);
  2. PCB焊盘设计:需匹配3x3mm封装的焊盘尺寸(建议焊盘长1.5mm×宽1.0mm),避免虚焊、假焊;
  3. 散热考虑:长期工作在额定电流附近时,可在焊盘附近增加散热铜箔(面积≥10mm²),降低绕组温度;
  4. 精度匹配:±20%精度不适用于医疗设备、高精度仪表等对电感值要求苛刻的场景。

六、品牌与可靠性说明

长江微电(cjiang)是国内专注电感研发的厂商,产品通过RoHS、REACH环保认证,FNR3015S151MT采用成熟磁胶屏蔽工艺,批量生产一致性好(电感值偏差控制在±20%以内),焊接合格率>99.5%,适合工业级与消费级产品的批量应用。

该产品凭借微型封装、低EMI与稳定性能,成为低功耗电路电感选型的优先方案之一。

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
