FNR5040S3R6MT 功率电感产品概述
一、产品基本定位
FNR5040S3R6MT是长江微电（cjiang）推出的一款磁胶屏蔽贴片式（SMD）功率电感，核心用于电子设备的功率转换、滤波及储能电路。凭借小型化封装、低损耗及稳定的电磁性能，适配对空间紧凑性和电磁兼容性（EMC）要求较高的通用场景，是中等功率电路的优选电感元件。
二、核心电气参数解析
该电感的关键性能参数明确，覆盖多数功率电路的设计需求：
- 电感值与精度：标称电感值为3.6μH，精度±20%，无需额外高精度匹配即可满足DC-DC转换器、滤波电路的电感量要求；
- 电流承载能力：额定连续电流（Iₐᵣₐₜₑₐ）为3.7A（长期稳定工作的最大连续电流，超此值会加剧损耗发热）；饱和电流（Iₛₐₜ）为4.4A（磁芯饱和临界电流，此时电感值显著下降，设计需避免电流峰值超过）；
- 直流损耗：直流电阻（DCR）仅34mΩ，低DCR意味着直流路径损耗小，可有效降低功率电路发热，提升整体效率；
- 屏蔽特性：磁胶屏蔽结构大幅减少电感对外电磁辐射，同时降低外部磁场对自身电感值的干扰，符合EMC规范。
三、物理特性与封装
- 封装规格：采用表面贴装（SMD）封装，尺寸为5×5mm（典型5040封装，长度5.0mm、宽度5.0mm），高度适配小型化设计，节省PCB空间；
- 结构特点：磁胶屏蔽不仅优化EMI性能，还增强抗振动、抗冲击能力，适合便携式设备或工业级应用的环境要求；
- 焊接兼容性：支持回流焊、波峰焊等常规SMT工艺，适配自动化生产，降低组装成本。
四、典型应用场景
该电感的性能参数匹配以下场景：
- 便携式电子设备：笔记本电脑、平板电脑、智能手表的DC-DC降压/升压模块（如CPU供电、电池充电电路），小型化封装节省内部空间；
- 电源模块：小型开关电源、LED驱动电源（低功率LED照明、显示屏背光），低DCR提升电源效率，降低发热；
- 通信设备：路由器、交换机的电源滤波电路，磁胶屏蔽减少电磁干扰，保证信号传输稳定；
- 工业控制：小型PLC、传感器模块的电源电路，稳定的电流承载能力适配中等功率负载。
五、产品优势总结
- EMC性能优异：磁胶屏蔽抑制电磁辐射，无需额外屏蔽措施，简化电路设计；
- 效率与发热平衡：34mΩ低DCR减少直流损耗，3.7A额定电流下发热可控，提升设备可靠性；
- 空间利用率高：5×5mm封装适配高密度PCB布局，满足小型化产品需求；
- 性能稳定可靠：长江微电工艺保证参数一致性，4.4A饱和电流较额定电流高18.9%，降低过流风险；
- 成本可控：±20%精度适合通用场景，平衡性能与成本，适合批量应用。
六、品牌与可靠性保障
长江微电作为国内专注于磁性元器件的制造商，产品经过温度循环、耐焊接热、振动等可靠性测试，符合RoHS环保标准，可满足不同行业质量要求，为批量生产提供稳定供应。

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.
