FNR3015S1R5MT 产品概述
一、产品简介
FNR3015S1R5MT 是长江微电（cjiang）推出的一款功率型磁胶屏蔽电感，封装为表贴（SMD），外形尺寸 3.0 × 3.0 mm，适用于空间受限的中低功率开关电源与滤波场合。器件采用磁性封装工艺，既保证了较高的电流处理能力，又降低了磁场泄露，便于密集布板设计。
二、主要特性
- 标称电感值：1.5 μH，公差 ±20%
- 额定电流（Ir）：2.2 A（长期允许通过的稳态电流）
- 饱和电流（Isat）：2.7 A（电感降到额定值一定比例时的参考）
- 直流电阻（DCR）：约 65 mΩ
- 类型：磁胶屏蔽功率电感，SMD 封装，3×3 mm 外形
三、电气与热性能点评
- DCR 为 65 mΩ，按照 I^2·R 计算，在额定电流 2.2A 下的铜损约 0.31 W，选型时需考虑热升与周围散热条件。
- 饱和电流 2.7A 指示在冲击或短时过载情况下电感值会明显下降，长期工作电流建议低于额定电流以保证电感稳定。
- ±20% 的电感公差适合功率滤波与能量传输应用，但对高精度滤波回路需留余量。
四、典型应用场景
- DC–DC 降压/升压模块中的储能与输出滤波电感
- 电源输入滤波与电磁干扰抑制（EMI 滤波器）
- 手持设备、网络设备及工业控制中中低功率电源模组
- LED 驱动及其他需要较高峰值电流承受能力的场合
五、封装与安装建议
- 以 3×3 mm 尺寸为基准，焊盘应提供足够的散热铜箔，尽量缩短与输入/输出电容之间的走线以降低寄生阻抗。
- 焊接工艺按一般 SMD 规范执行，推荐回流焊温度曲线并避免长时间高温以防磁性材料性能变化。
- 布局时注意将电感与敏感信号线保持一定间距，虽为屏蔽结构但仍建议合理走线以降低耦合。
六、选型与使用注意事项
- 若系统可能出现恒定高电流或较大脉冲电流，建议留有 20–30% 的电流裕量，避免进入饱和区。
- 对于要求低损耗或高效率的设计，可通过计算 I^2·R 损耗并评估器件温升，必要时选择更低 DCR 或更大封装的产品。
- 在高频应用中关注电感的频率特性与磁芯损耗，若工作频率接近 MHz 级别，需核实厂方提供的频率响应曲线。
七、可靠性与包装
长江微电的功率电感通常提供标准的卷盘式 SMD 包装，便于自动贴装与批量生产；产品通过常见的电气与环境可靠性试验（如温循环、湿热、振动等），建议在采购时索取完整的规格书与可靠性报告以满足特殊行业要求。
总结：FNR3015S1R5MT 以 3×3 mm 小型化封装提供 1.5 μH 的能量存储与较好的电流承载能力，适合空间受限且需承担 1–2A 级别负载的电源与滤波场合。选型时重点关注实际工作电流、损耗与散热条件，以确保长期稳定运行。

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.
