FNR3015S100MT 产品概述
一、概述
FNR3015S100MT 是长江微电（cjiang）推出的一款表贴磁胶屏蔽功率电感，封装尺寸为 3.0 × 3.0 mm（常见标注 3015）。该器件设计用于开关电源、DC-DC 降压模块、滤波和电流旁路等场景，针对小尺寸、高可靠性和中等电流传输要求进行了优化。典型电感值为 10 µH，公差 ±20%，在空间受限的移动电源、通信和工业电子应用中具有良好适配性。
二、主要参数
- 型号：FNR3015S100MT
- 品牌：cjiang（长江微电）
- 电感值：10 µH ±20%
- 额定电流（Irms）：900 mA
- 饱和电流（Isat，规范电感降至初始值的 30% 时）：920 mA
- 直流电阻（DCR）：325 mΩ（典型）
- 类型：磁胶屏蔽电感（屏蔽式功率电感）
- 封装：SMD，3 × 3 mm
三、特点与优势
- 小型化：3015 小封装便于高密度 PCB 布局。
- 屏蔽结构：磁屏蔽设计降低对周围元件的电磁干扰（EMI），有利于信号完整性。
- 容错能力：±20% 公差适用于一般功率滤波用途，允许一定工差用于成本与性能折衷。
- 可靠的电流承载：900 mA 的额定电流可满足一般中小功率转换器的需求；920 mA 的饱和电流说明在接近额定工况下仍能维持工作。
四、典型应用
- 手机充电器、移动电源 DC-DC 模块
- 工业和通信设备的输入/输出滤波
- 电源管理子系统中的能量储存与滤波环节
- 低功率电机驱动及传感器电源滤波
五、设计与选型注意事项
- 电流余量：建议在实际应用中对额定电流进行 20% 以上的余量设计，避免长期工作在饱和临界区导致电感值下降与发热。
- 温升与散热：高 DCR（325 mΩ）会在大电流下产生显著损耗（P≈I²·DCR），需评估 PCB 的散热能力并考虑铺铜或加热沉。
- 饱和特性：当工作电流接近 Isat 时电感会明显下降，应避免长期在该区域工作以免影响电路稳定性。
- PCB 布局：输入/输出环路尽量短且宽，电感与开关器件（MOSFET、肖特基）放置紧凑以减少寄生电感和辐射。
- 回流焊兼容性：遵循常规无铅回流温度曲线，避免超过元件厂商对温度循环或峰值温度的限制。
六、可靠性与封装
磁胶屏蔽结构提高了机械强度与抗震性能，适用于常温到较高温度范围的商业和工业级应用。SMD 封装方便自动贴片与回流焊接，出厂前通常经过焊接热冲击与机械冲击测试；实际使用时建议参考长江微电的具体可靠性报告与焊接规范。
七、订购与参考
型号：FNR3015S100MT；如需批量采购或获取完整数据手册（包括电感频率响应、饱和曲线、温度特性及回流焊工艺参数），请联系长江微电授权经销或技术支持，获取最新的样片与测试数据以保证设计一致性与可靠性。

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.
