FNR3015S680MT 磁胶屏蔽功率电感产品概述

FNR3015S680MT是长江微电(cjiang)推出的一款小体积磁胶屏蔽功率电感,针对便携电子、低功耗IoT终端等场景的电源管理需求优化,兼具小封装、低EMI、稳定电气性能等特点,是小型化电路设计的常用选型之一。

一、产品基本定位与核心特性

该电感属于SMD型磁胶屏蔽功率电感,核心定位为“小功率电源电路的高效储能元件”,核心特性包括:

  1. 高电磁屏蔽性:采用磁胶包裹结构,相比非屏蔽电感可显著降低对外电磁辐射(EMI),同时减少外界干扰对电感性能的影响,适配对EMI敏感的电子设备;
  2. 超小封装体积:3×3×1.5mm的紧凑尺寸,兼容自动化贴装工艺,满足智能穿戴、TWS耳机等便携设备的小型化设计需求;
  3. 稳定的电气性能:电感值精度控制在±20%范围内,额定电流与饱和电流匹配合理,可在低功耗场景下稳定工作。

二、关键电气参数详解

FNR3015S680MT的电气参数针对小功率应用做了针对性设计,核心参数需重点关注以下几点:

  • 电感值与精度:标称电感值68μH,精度±20%,适用于对电感值要求无极端苛刻的DC-DC降压/升压电路(如1-5V输入转3.3V输出的电源模块);
  • 电流特性:
    • 额定电流(Idc):310mA——指电感在环境温度25℃下,连续工作时电感温度上升不超过40℃的最大直流电流,是实际应用中的推荐最大工作电流;
    • 饱和电流(Isat):370mA——指电感值下降30%(厂家定义)时的临界电流,实际设计中需避免电流超过此值,否则会导致电感储能能力骤降,影响电路稳定性;
  • 直流电阻(DCR):2.7Ω——电感绕组的直流电阻,影响功率损耗(损耗公式:P=I²×DCR),310mA工作电流下损耗约0.26W,符合低功耗设备的能耗要求。

三、封装与物理特性

该电感采用SMD表面贴装封装,具体物理参数如下:

  • 封装尺寸:3×3×1.5mm(长×宽×高),对应行业内“3015”封装规格,适配常规贴片机的吸嘴尺寸,可实现高速批量贴装;
  • 磁胶屏蔽结构:绕组外围包裹高性能磁胶材料,既保证电感的储能效率,又通过磁屏蔽减少电磁干扰,适合与射频电路、传感器等敏感模块近距离布局;
  • 引脚设计:采用两端扁平引脚,焊接可靠性高,可承受常规回流焊工艺(如260℃峰值温度下10秒左右),适配无铅焊接要求。

四、典型应用场景

FNR3015S680MT的参数特性使其在以下场景中表现突出:

  1. 智能穿戴设备:如智能手环、智能手表的低功耗电源模块(DC-DC降压电路),小体积可节省内部空间,低EMI不干扰心率、运动传感器;
  2. TWS无线耳机:耳机本体及充电盒的电源管理电路,310mA额定电流满足耳机充电、音频解码等小功率需求;
  3. 物联网(IoT)终端:如温湿度传感器、智能门锁的低功耗模块,稳定的电感性能适配电池供电的长续航要求;
  4. 小型消费电子:如蓝牙音箱、便携式充电器的辅助电源电路,磁屏蔽特性减少对音频信号的干扰。

五、品牌与品质背书

该产品由国内知名电感制造商长江微电(cjiang) 生产,品牌在功率电感领域拥有成熟的研发与生产工艺:

  • 磁胶材料采用自主配方,兼顾屏蔽效果与电感效率,高温下(-40℃至+125℃)性能稳定;
  • 生产过程通过ISO9001质量体系认证,每批次电感均经过电感值、DCR、电流特性等全项测试,保证一致性;
  • 广泛应用于国内多家消费电子、IoT企业的量产项目,市场验证充分。

总结:FNR3015S680MT是一款专为小功率、小型化电子设备设计的磁胶屏蔽功率电感,平衡了体积、EMI性能与电气稳定性,是电源电路设计中的高性价比选型。

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
