FNR6045S2R7NT — 6.3A 2.7µH 磁胶屏蔽功率电感产品概述
一、产品简介
FNR6045S2R7NT 为长江微电（cjiang）推出的一款表面贴装磁胶屏蔽功率电感，封装尺寸约 6×6 mm。该器件面向高电流开关电源与电源管理场景，兼顾小体积与较高电流承载能力，适合用于降压转换器、负载滤波及各类开关电源模块。
二、主要规格
- 电感值：2.7 µH（公差 ±30%）
- 额定电流（Ir）：4.7 A（连续载流能力）
- 饱和电流（Isat）：6.3 A（电感下降显著的临界点）
- 直流电阻（DCR）：20 mΩ（典型值）
- 类型：磁胶屏蔽电感（SMD）
- 封装：表面贴装，尺寸约 6×6 mm
- 品牌：cjiang（长江微电）
（以上数据用于选型与设计验证，具体器件标注请以厂家出厂数据为准。）
三、性能特点
- 高电流承载：4.7 A 连续额定电流，短时可承受 6.3 A 饱和电流，适合中高功率密度设计。
- 低 DCR 损耗：20 mΩ 级别直流电阻，减小导通损耗，提高系统效率。
- 磁胶屏蔽：良好的磁屏蔽设计，减小对周围敏感器件的磁干扰，利于密集布板。
- SMD 封装，便于自动化贴装与回流焊工艺。
四、典型应用场景
- DC-DC 降压（Buck）转换器电感
- 服务器、电源模块与通信设备的输出滤波
- 工业控制、仪器仪表的电源管理
- 无人机、电动工具、便携设备的高能量密度电源系统
五、使用建议与注意事项
- 布局：尽量将电感靠近开关管与输出电容，减小环路面积；输入与输出走线短而粗，降低寄生阻抗。
- 热管理：在高电流与高纹波条件下电感会发热，应留意周围器件耐热限值并确保良好散热路径。
- 饱和裕量：设计时应保证工作电流低于 Ir，并考虑纹波电流与瞬态冲击，避免长期运行接近 Isat。
- 焊接工艺：兼容标准 SMT 回流焊温度曲线（请参照厂家推荐焊接资料），避免超温或重复回流。
- 储存包装：防潮、防尘，避免长期在高温高湿环境中存放以保持性能稳定。
六、选型与验证建议
- 若系统纹波电流较大或有较强瞬态负载，优先选择额定电流与饱和电流有更大裕量的型号。
- 在样机阶段进行热升测试、直流损耗及在工作频率下的实际电感值测量，确认满足系统效率与稳定性要求。
- 如需更低 DCR 或更紧凑尺寸，可与长江微电询价其它系列或定制方案。
如需器件样片、封装尺寸图或更详细的电气特性曲线（温度系数、频率特性、纹波电流引起的电感下降曲线等），建议直接联系长江微电技术支持获取原始数据表与应用笔记。

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.
