FNR6020S4R7MT 产品概述
一、产品简介
FNR6020S4R7MT 是长江微电（cjiang）推出的一款磁胶屏蔽型功率电感，封装为 SMD，外形尺寸 6.0×6.0mm（6020 尺寸级）。标称电感值 4.7µH，公差 ±20%，额定直流电流 2.5A，饱和电流（Isat）3.6A，直流电阻（DCR）约 75mΩ。该器件针对开关电源、DC-DC 降压稳压器及各类电源滤波场合优化设计，兼顾磁屏蔽性与较高电流承载能力。
二、主要性能参数
- 电感值：4.7µH ±20%
- 额定电流（Ir）：2.5A（推荐连续工作电流）
- 饱和电流（Isat）：3.6A（电感量显著下降时的参考电流，具体以厂家曲线为准）
- 直流电阻（DCR）：≈75mΩ
- 封装：SMD，尺寸 6×6mm（6020）
- 类型：磁胶屏蔽功率电感
三、产品特点与优势
- 屏蔽结构：磁胶屏蔽设计减小磁通外泄，利于邻近元件布局与 EMI 控制。
- 高电流承载：2.5A 额定电流适合中功率降压转换器，饱和点 3.6A 提供瞬态裕量。
- 紧凑封装：6×6mm 尺寸在保证电感量的同时节省 PCB 面积，适合空间受限应用。
- 良好散热：较低封装热阻及合理的 DCR，使器件在额定电流下具有可接受的功耗表现。
四、典型应用
- 同步/异步降压转换器（Buck）
- 电源管理模块（PMIC）输入/输出滤波
- 工业与通信电源、网络设备电源模块
- 消费电子移动电源与充电器
五、使用建议与注意事项
- 电流与发热：按 I²·R 计算在额定电流 2.5A 时的损耗约为 0.47W（0.075Ω×2.5²），需考虑 PCB 散热与周围器件温升；瞬态达到 Isat 时电感量会下降，应留足裕量避免长期工作在饱和区。
- 布局要点：将电感靠近开关器件布置，尽量缩小电流回路面积；在器件下方和周围使用铜箔加大散热面积，并在地层或电源层打通多颗热/电流过孔以改善散热与降低寄生阻抗。
- EMI 考虑：虽为屏蔽型，但仍需与输入电容、输出电容配合，合理选择旁路电容和回路布局以抑制开关噪声。
- 环境与可靠性：遵循厂家推荐的回流焊温度轮廓，避免超出封装和材料允许的温度上限；大电流环境下注意长期热循环对焊点和器件性能的影响。
六、封装与可靠性
FNR6020S4R7MT 为标准 SMD 贴片件，适用于自动贴装与回流焊工艺。磁胶屏蔽结构在振动与机械应力下具有良好稳定性，常见通过潮湿、温度循环与振动测试。具体可靠性指标与典型电感-电流特性曲线请参考厂方数据手册以获得更准确的工程数据。
七、选型建议与订购信息
选择时优先按最大工作电流与电感衰减裕度评估：若系统有较大纹波电流或长时间高负载建议选择额定电流更高或更低 DCR 的型号。订购时请注明型号 FNR6020S4R7MT、数量与交货期，并向长江微电（cjiang）索取最新的规格书与样品测试数据以便验证。

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.
