FNR3010S2R2NT — 2.2µH 1.5A 磁胶屏蔽电感产品概述
一、产品概述
FNR3010S2R2NT 是长江微电（cjiang）推出的一款小型磁胶屏蔽功率电感，封装为 SMD，外形约 3×3 mm，标称电感值 2.2µH（公差 ±30%），适用于空间受限的开关电源与电源滤波场合。该器件兼顾体积与大电流能力，额定电流 1.4A，饱和电流（Isat）可达 1.5A，适合中低功率点对点电源及电源滤波使用。
二、主要参数
- 电感值：2.2µH ±30%
- 类型：磁胶屏蔽电感（屏蔽式 SMD 功率电感）
- 额定电流（Ir）：1.4A
- 饱和电流（Isat）：1.5A（电感下降至额定值一定比例时测定）
- 直流电阻（DCR）：约 143mΩ
- 封装形式：SMD，尺寸约 3×3 mm
- 典型应用：DC-DC 降压模块、功率滤波器、输入/输出滤波、点对点供电
三、产品特点
- 体积小、轻量化：3×3 mm 封装适合高密度贴装板设计。
- 良好电流承载能力：1.4A 额定电流能满足常见移动及嵌入式电源需求。
- 屏蔽设计：减少电磁辐射与相互干扰，便于在噪声敏感电路中使用。
- 稳定性与可靠性：磁胶材料在常温工况下保持较好的电感稳定性和抗振动性。
四、典型应用领域
- 主流开关稳压器（降压型 DC-DC）中的输出或输入扼流圈。
- 模拟与数字混合电路的电源滤波与去耦。
- 手机、平板、可穿戴设备、通信模块及工业控制设备的点对点电源供给。
- EMI 抑制电路与电源噪声治理。
五、使用建议与注意事项
- 电流取用建议：为保证长期可靠性，设计时建议工作电流低于额定电流 1.4A，避免长时间在接近 Isat 的条件下工作以防止电感值显著下降。
- 温度与热管理：器件在高温、高负载下 DCR 与电感值可能随温升变化，布局时应预留散热路径并考虑必要的降额。
- 焊接工艺：适用于常规 SMD 回流焊流程，建议参照厂家回流曲线与 PCB 焊盘推荐，避免超出规范的重熔与长时间高温。
- 安装与布局：靠近电源芯片的走线应尽量短且宽，输入输出旁配合合适的电容以优化环路性能与减小纹波。
- 存储与搬运：避免受潮、强磁场及剧烈机械冲击，标准环境下密封保存以保证焊接与电气性能。
六、包装与采购
- 封装：SMD 卷带（常规供给方式，根据客户需求可按量包装）。
- 型号与品牌：FNR3010S2R2NT，品牌 cjiang（长江微电）。
- 选型提醒：在选型阶段请参考实际工作电流峰值、纹波要求与饱和裕度，必要时与供应商沟通样片测试电流-电感曲线资料。
如需样片、电气特性曲线（L vs I、频率响应）、回流焊曲线或 PCB 推荐焊盘，请联系供应商或长江微电技术支持获取更详尽的规格书与测试数据。

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.
