FNR5040S502MT 磁胶屏蔽功率电感产品概述
一、产品基本定位与品牌背景
FNR5040S502MT是长江微电（cjjiang）推出的磁胶屏蔽贴片功率电感，属于该品牌FNR系列的小体积高电感产品。产品针对中低功率电路的紧凑化设计需求，平衡了电感量、电流承载能力与电磁干扰（EMI）控制，适用于消费电子、小型电源及物联网终端等场景，兼具成本优势与可靠性。
二、核心电气参数详细说明
各参数直接决定产品适用场景，关键指标如下：
- 电感值与精度：标称电感量为5mH（编码“502”，即5×10²μH），精度±20%。该范围满足大多数中低功率电源电路的电感量需求，无需额外高精度筛选成本。
- 电流承载能力：
- 额定电流（98mA）：电感在额定工作条件下（典型环境温度+25℃），电感量变化不超规格要求的最大工作电流；
- 饱和电流（Isat=130mA）：磁芯饱和时的最大电流（此时电感量下降≤30%，行业通用标准），比额定电流高32%，为电路过载提供安全裕量。
- 直流电阻（DCR）：43.16Ω。低直流电阻意味着电感直流偏置下损耗小、发热少，可提升电路整体效率，适合长期连续工作。
- 屏蔽特性：采用磁胶屏蔽结构，相比普通屏蔽电感，能更有效地抑制电磁辐射与传导干扰，降低对周边敏感电路的影响。
三、机械与封装特性
- 封装尺寸：SMD贴片封装，规格为5×5mm（典型5.0×5.0×4.0mm紧凑尺寸），适配高密度PCB布局，满足便携设备小型化需求。
- 焊接兼容性：支持标准回流焊工艺，引脚设计符合IPC标准，焊接可靠性高，适合自动化生产。
- 环境适应性：磁胶屏蔽电感具备宽温工作特性（典型-40℃~125℃），可适应不同场景温度变化；抗振动、抗冲击性能良好，适合移动设备或工业环境。
四、典型应用场景
结合参数与特性，FNR5040S502MT适用于以下场景：
- 消费电子便携设备：智能手环、手表、蓝牙耳机等可穿戴设备的电源管理电路（DC-DC转换），小体积与低损耗匹配便携需求。
- 小型电源模块：5V转3.3V、3.3V转1.8V等中低功率降压电路，电感量稳定保证输出电压精度。
- 物联网终端：小型传感器节点、低功耗路由器等设备，磁胶屏蔽减少设备间电磁干扰，提升通信稳定性。
- 小型家电与玩具：加湿器、台灯、儿童智能玩具的控制电路，性价比与可靠性满足批量应用。
五、产品核心优势总结
- EMI控制优异：磁胶屏蔽有效降低电磁干扰，无需额外滤波电路即可满足低干扰要求。
- 效率与可靠性平衡：低DCR减少发热损耗，饱和电流裕量充足，长期工作稳定性高。
- 小体积高电感：5×5mm封装实现5mH电感量，同类产品中体积优势明显，适配紧凑设计。
- 成本可控：长江微电成熟产品线，性价比高，适合中小批量及大规模应用。
该产品通过参数与结构设计，精准匹配中低功率紧凑电路的需求，是消费电子、物联网等领域的实用选择。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
