FNR6020S470MT 产品概述
一、产品简介
FNR6020S470MT 是长江微电（cjiang）推出的一款磁胶屏蔽功率电感，标称电感值 47 μH，公差 ±20%，为表面贴装（SMD）封装，外形尺寸约 6 × 6 mm。该器件面向小型化电源滤波与能量储存场合设计，兼顾体积、成本与磁屏蔽性能，适用于中低电流的 DC-DC 降压/升压、输入滤波与 EMI 抑制等电路。
二、主要参数
- 电感值：47 μH ±20%
- 额定电流（Ir）：900 mA
- 饱和电流（Isat）：900 mA（电感显著下降点）
- 直流电阻（DCR）：559 mΩ
- 类型：磁胶屏蔽电感（屏蔽结构）
- 封装：SMD，尺寸约 6 mm × 6 mm
- 品牌：cjiang（长江微电）
三、特性与优势
- 小型化：6×6mm SMD 封装便于高密度布局，适合空间受限的电源模块。
- 屏蔽性能：磁胶屏蔽结构减少对周边元件的磁干扰，利于缩减系统 EMI。
- 成本与可得性：面向批量应用，适合中低成本设计需求。
- 结构稳健：适配常规回流焊工艺，可靠性良好。
四、典型应用场景
- 小功率 DC-DC 降压/升压转换器的储能电感与输入/输出滤波；
- 电源滤波器（PI、LC 网络）用于去耦与抑制开关噪声；
- 工业控制、通信模块、消费电子等要求磁屏蔽与中低电流的场合。
五、使用与设计注意事项
- 电流与发热：按 DCR=559 mΩ，在额定电流 0.9 A 条件下的直流损耗约为 I^2·R ≈ 0.45 W，器件温升不可忽视。建议在持续导通场合对电流进行降额设计（常建议连续电流按 60%–80% 的 Isat 取值），并考虑散热与周围布板。
- 饱和影响：Isat=900 mA 时电感将开始显著下降，若电路对电感值稳定性敏感，工作电流应低于此值以避免性能变化。
- 焊接与组装：推荐按 PCB 制造与组装行业标准（如 IPC/JEDEC）进行回流焊；在回流及波峰焊过程遵循相应温度曲线以避免过热。
- 布局建议：输入/输出电感应配合足够的旁路电容，尽量缩短高频回路回路面积，减少 EMI。屏蔽虽然能抑制外泄磁场，但仍应留意敏感器件间距。
六、封装与订购信息
- 型号：FNR6020S470MT
- 封装形式：SMD（6×6 mm）
- 品牌：cjiang（长江微电）
- 适用于 SMT 贴装流程，出货通常为卷带或盘装，订购时请确认包装规格与最小起订量。
七、可靠性与测试建议
- 可靠性验证：建议在设计验证阶段进行温升测试、振动测试及湿热循环测试，重点关注长期高温或高纹波电流下的电阻与电感漂移。
- 评估方法：在目标系统条件（最大纹波、电流、环境温度）下测量实际电感和损耗，评估温升与寿命是否满足需求。
备注：本文档基于器件主要参数给出应用建议，具体电气特性（如频率响应、阻抗曲线等）应以厂方详细数据手册与样片测试为准。

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.
