FNR3015S120MT 产品概述
一、产品简介
FNR3015S120MT 是长江微电（cjiang）推出的一款表面贴装功率电感，规格为 12 μH±20%，额定电流 890 mA，饱和电流（Isat）900 mA，直流电阻（DCR）约 416 mΩ。器件采用磁胶屏蔽结构，封装为 SMD，外形尺寸近似 3×3 mm，专为空间受限的降压转换器与电源滤波场合设计。
二、主要特性
- 电感值：12 μH，公差 ±20%；
- 额定电流：890 mA，饱和电流：900 mA（注意额定与饱和值接近，应留安全裕量）；
- 直流电阻：约 416 mΩ，适合中低功率传输；
- 结构：磁胶屏蔽，降低电磁干扰（EMI）和相互耦合；
- 封装：SMD 贴片，适配自动化贴装与回流焊工艺。
三、典型应用场景
- 手机、平板等便携设备的降压转换器（Buck）输出侧滤波；
- 工业与消费类电子的电源管理模块；
- EMI 抑制与信号完整性改善的电源滤波环节；
- 小功率 LED 驱动与电池供电系统。
四、设计与选型建议
- 电流裕量：由于 Isat 与额定电流接近，推荐在实际设计中保留 20% 以上裕量，避免因大电流时电感饱和导致电感值显著下降；
- 温升与功耗：DCR 较高时在高电流下会产生较大功率损耗，应考虑热管理与散热路径设计；
- 降压拓扑：适用于开关频率较低或中频应用；若工作于高频应验证电感的交流特性与自谐频率；
- PCB 布局：电感与功率开关元件尽量靠近，减小回流环路；采大面积焊盘以降低接触电阻和助于散热。
五、可靠性与工艺
- 建议采用标准回流焊流程进行贴装，遵循厂商焊接温度曲线；
- 存储与处理时避免机械冲击与强磁场干扰；
- 出货包装适配自动化贴片机，便于量产使用。
六、选型注意事项
在选择 FNR3015S120MT 时，应综合考虑负载电流峰值、占空比与环境温度对电感值与 DCR 的影响；若系统存在较高峰值电流或要求更低损耗，可考虑 DCR 更低或 Isat 更高的替代型号。若需进一步技术参数（如自谐频率、温度系数、封装详图和焊盘推荐），建议联系供应商获取详细数据手册与样品验证。

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.
