FNR5020S101MT 功率电感产品概述
一、产品简介
FNR5020S101MT 是 cjiang（长江微电）推出的一款磁胶屏蔽功率电感，封装为 SMD，外形尺寸约 5×5 mm，标称电感值 100 μH，精度 ±20%。该器件以磁胶屏蔽结构为主，适用于对体积和屏蔽性有一定要求的中低功率电源滤波与能量存储场合。
二、主要参数
- 电感值：100 μH（±20%）
- 额定电流：580 mA
- 饱和电流（Isat）：580 mA（在此电流下电感量明显下降）
- 直流电阻（DCR）：1.43 Ω
- 类型：磁胶屏蔽电感
- 封装：SMD，5×5 mm
- 品牌：cjiang（长江微电）
三、产品特性
- 小型化设计，适合 SMT 贴装与自动化生产流程。
- 磁胶屏蔽结构降低外泄磁场，便于与其他敏感元件并列布局。
- 标称电感值较大（100 μH），适用于低频滤波和能量存储。
- 注意 DCR 较高，在接近额定电流时会产生显著 I^2R 损耗并导致发热（在 580 mA 时损耗约 0.48 W），因此需关注热管理与实际电流余量。
四、典型应用
- 开关电源输入/输出滤波（尤其是需要较大电感量的低频段滤波）
- DC-DC 降压/升压电路的能量存储（中低功率）
- LED 驱动与电源噪声抑制
- 一般功率管理模块、汽车电子低速滤波（需评估温升与可靠性）
五、封装与安装建议
- 建议采用与元件尺寸对应的 PCB 焊盘与过孔布局，遵循 SMT 回流焊工艺。
- 回流焊峰值温度与时间以制造商推荐为准；若无明确数据，请按主流 SMD 器件回流曲线（IPC 标准）控制。
- 焊接后建议做外观与接触性检查，避免因焊接缺陷引起电阻或热阻异常。
六、使用与注意事项
- 由于 DCR 较高，长期在额定电流工作会产生较大热量，建议在设计中预留电流余量（例如额定电流的 50%~70% 范围内工作），以降低温升并延长寿命。
- 饱和电流与额定电流相同，接近或超过该电流时电感值会明显下降，电路需考虑饱和对性能的影响。
- 在高温或高湿环境下使用应注意可靠性测试，包括温升、振动与热冲击验证。
- 大电流脉冲场合需评估瞬态饱和与热冲击效应。
七、选型与质量保证
- 选型时除电感值与电流外，还应综合考虑 DCR、封装尺寸与温升要求；若需更低损耗的方案，可考虑 DCR 更小、体积更大的绕线电感或功率电感系列。
- 订购时请核对完整型号 FNR5020S101MT 与供应商出货资料（样片评估、批次一致性、可靠性测试报告等），并依据应用场景做必要的样机验证与老化测试。
如需我帮忙计算在特定工作电流下的损耗与温升估算，或提供与之参数相近但 DCR 更低的替代型号建议，可提供工作条件与电路信息，我将进一步分析。

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.
