FNR6028S1R5MT — 长江微电 6.6A 功率屏蔽电感产品概述
一、产品简介
FNR6028S1R5MT 是长江微电（cjiang）推出的一款表面贴装功率电感，封装尺寸 6×6mm，电感量 1.5µH（公差 ±20%），额定电流 5A，饱和电流（Isat）6.6A，直流电阻（DCR）约 17mΩ，属磁胶屏蔽型结构。该器件针对中大电流开关电源与电源滤波场景设计，兼顾体积、导通损耗与抗饱和能力。
二、主要特性
- 电感值：1.5µH，公差 ±20%
- 额定电流：5A（连续载流能力）
- 饱和电流 Isat：6.6A（在此电流下电感降至初始值的特定比例）
- 直流电阻 DCR：约 17mΩ（低损耗设计，有利于提升转换效率）
- 封装：SMD，尺寸 6×6mm，便于自动贴装与高密度布局
- 结构：磁胶屏蔽，减少磁泄漏与对周围电路的干扰
三、典型应用场景
- 升/降压（Buck/Boost）转换器的储能电感
- 输入/输出滤波器与电源去耦（SMPS）
- LED 驱动电源、高功率电机驱动供电模块
- 通信设备、电源模块与汽车电子（在满足温度与符合性要求时）
四、设计与选型建议
- 电流裕量：实际工作电流应低于额定电流 5A，并考虑脉冲/峰值电流的影响；若存在长时间高负载或高环境温度，应适当选用更高额定电流的型号或加以散热设计。
- 饱和裕量：在可能出现短时高峰电流的应用，参考 Isat=6.6A，确保电路在峰值时仍维持足够电感量以避免性能退化。
- 损耗评估：DCR≈17mΩ，为评估 I^2R 损耗与发热提供依据；高效率设计中应把 DCR 纳入功耗预算。
- 温度与老化：磁性材料对温度敏感，长期高温会影响电感值与损耗，建议遵循器件的环境温度与回流焊工艺规范。
五、PCB 布局与焊接注意
- 采用短而宽的铜箔连接，减小寄生电阻与电感，提升散热。
- 将电感与开关管、二极管等热源保持合理距离，避免局部过热。
- 推荐使用符合回流焊温度曲线的焊接工艺，避免过度加热影响磁胶或封装应力。
- 对 EMI 敏感电路，可借助器件的屏蔽特性并配合布局、滤波网络优化。
六、包装与订购信息
- 封装形式：SMD 卷带盘装（具体包装形式与最小订货量请咨询供应商或经销商）。
- 型号完整标识：FNR6028S1R5MT，品牌：cjiang（长江微电）。下单时请确认数量、交期及是否需 RoHS/车规等特殊认证。
七、总结
FNR6028S1R5MT 以 6×6mm 的小体积实现 5A 连续电流与 6.6A 的较高饱和电流，DCR 约 17mΩ，适合中高功率密度的开关电源与滤波场合。选型时应综合考虑电流裕量、热管理及 PCB 布局，确保长期可靠运行。如需更详细的电气特性曲线、温升数据或封装图纸，可向长江微电索取器件数据手册与样品测试报告。

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.
