FNR6045S2R2MT 产品概述
一、产品简介
FNR6045S2R2MT 是长江微电（cjiang）推出的一款 SMD 功率电感，规格为 2.2µH ±20%，额定电流 5A，饱和电流（Isat）7.4A，直流电阻（DCR）约 18mΩ。器件采用磁胶屏蔽结构，外形尺寸 6×6mm，适合空间受限且对电磁兼容有一定要求的中高电流电源设计。
二、主要性能特点
- 大电流承载：额定电流 5A，饱和电流 7.4A，可满足升降压转换器和电源模块的高瞬态载流需求。
- 低损耗：18mΩ 的低 DCR 有助于降低铜损，提高转换效率并减少发热。
- 良好屏蔽性：磁胶屏蔽设计抑制漏磁，利于系统 EMI 控制与邻近器件兼容。
- 紧凑封装：6×6mm SMD 形式，兼顾空间利用率与热散能力，适合自动贴装与回流焊工艺。
三、典型应用场景
- 同步降压 / 升降压（Buck/Boost）DC–DC 转换器电感
- 电源管理模块（PMIC）、电源滤波与储能回路
- LED 驱动、移动电源与工业电源等中高电流场合
- 对 EMI 有要求的嵌入式与通信设备电源部分
四、封装与安装建议
- SMD 贴装兼容常见回流焊温度曲线，建议遵循元件厂家或通用电子元器件回流焊工艺标准。
- 版图布线：电感两端应与输入/输出电容及开关管短连，尽量缩短高电流回路，防止寄生阻抗增加。
- 散热与布局：在高平均电流或高占空比工况下，保证周边铜箔面积以利散热；避免紧贴热敏元件。
五、选型与使用注意
- 峰值与纹波电流：实际电路中应根据纹波电流与峰值电流进行裕量选型，避免在接近饱和电流时长期工作。
- 温度与老化：在高温或长期过载环境下，电感参数会随温度变化，建议对关键应用进行热仿真与寿命评估。
- 测试验证：实际设计中建议在目标频段测量电感值、DCR 与频率特性，并评估 EMI 表现与效率影响。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
