FNR6020S150MT 产品概述
一、产品简介
FNR6020S150MT 是长江微电（cjiang）出品的一款功率型磁胶屏蔽贴片电感，额定电感 15 μH，封装为 SMD 6×6 mm。该器件兼顾电感量与抗磁干扰性能，适用于开关电源滤波、能量储存与电磁兼容（EMC）抑制等场合。
二、主要技术参数
- 电感值：15 μH
- 精度：±20%
- 额定电流：1.5 A
- 饱和电流（Isat）：1.4 A（在此电流值下电感会明显下降）
- 直流电阻（DCR）：约 189 mΩ
- 类型：磁胶屏蔽电感（屏蔽结构，减小漏磁）
- 封装：SMD，外形参考 6×6 mm
三、特点与优势
- 屏蔽结构：有效减小对周围元器件的磁干扰，便于在高密度 PCB 布局中使用。
- 体积/电流平衡：6×6 mm 的体积在提供 15 μH 电感量的同时，能承受约 1.4–1.5 A 的工作电流，适合中低功率电源用途。
- 稳定性：磁胶材料与屏蔽设计使得器件在频率范围内的特性更稳定，利于滤波与能量传输。
四、应用场景
- 开关电源输入/输出滤波（DC-DC 升压/降压转换器）
- 电源管理与负载去耦
- 通信设备、电池管理系统（BMS）中的噪声抑制
- 工业与消费电子中需兼顾小体积与中等电流的场合
五、使用建议与注意事项
- 饱和与降额：Isat 为 1.4 A，接近或超过此值时电感量会显著下降；建议在设计中将直流偏置电流控制于 Isat 的 70%–85% 范围内（例如不超过约 1.0–1.2 A）以保证性能余量。
- 损耗与温升：按 P = I^2·DCR 估算，在额定电流 1.5 A 时损耗约 0.425 W，器件会产生明显温升，建议在热设计上预留散热通道或采用风冷/散热铜箔与过孔。
- 滤波效果：考虑电感 ±20% 公差对谐振频点的影响，若对截止频率敏感，请在电路仿真时包含公差范围。
- 并联/串联：如需降低 DCR 或提升电流能力，可考虑并联多只电感，但需注意寄生和共享磁通影响；串联可提高电感量但会增加 DCR 和损耗。
- 焊接工艺：按通用 SMD 回流焊工艺（参考 IPC/JEDEC 规范）进行，避免超过器件允许的热循环次数并注意温度剖面以防材料性能退化。
六、封装与 PCB 安装建议
- 外形体积小，推荐在焊盘设计中使用与器件相匹配的焊盘尺寸与丝印定位，并在焊盘下方或周边布局热沉铜箔与必要的过孔以改善散热。
- 做好机械支撑：在有较强振动或热循环的应用中，建议在器件周围增加阻焊或粘接增强，以提高抗振性能。
- EMC 考量：尽量缩短与关键信号线路的距离，使用屏蔽和地平面配合可以进一步降低辐射和耦合噪声。
总结：FNR6020S150MT 为一款适用于中低功率电源滤波与抑噪的屏蔽型 SMD 功率电感，适合在体积受限但需一定电流承载与良好 EMI 表现的场合使用。设计时应重视直流偏置对电感的影响与 DCR 导致的功耗和温升，做好热和 PCB 布局优化。

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.
