FNR6045S220MT 产品概述
一、产品定位与简介
FNR6045S220MT 是长江微电（cjiang）推出的一款 SMD 封装功率电感，电感值 22µH，允许偏差 ±20%，额定电流 2.0A，饱和电流（Isat）2.2A，直流电阻（DCR）约为 116mΩ。器件采用磁性胶体屏蔽结构，6×6mm 封装，适合中小功率 DC-DC 转换器与电源滤波场合，对空间和成本有要求的表面贴装应用尤为合适。
二、主要特性
- 电感值：22µH ±20%（常规容差，适用于对精度要求不极高的滤波与储能场景）
- 额定电流：2.0A，饱和电流：2.2A（建议留有一定裕量以避免磁饱和）
- DCR：约 116mΩ（较低的直流电阻有利于降低铜损与发热）
- 屏蔽结构：磁胶屏蔽，减小外漏磁场，便于与周边元件紧密布局
- 封装：SMD，6×6mm，利于自动化贴装与紧凑 PCB 布局
三、典型应用场景
- 开关电源（buck、boost）输出滤波或储能电感
- 电源噪声抑制与输入输出滤波（尤其在便携设备、通信模块中）
- 2A 级别电源管理、电池供电系统与功率调节模块
- 对外漏磁场敏感的混合信号板或多电源模块
四、选型建议
- 饱和裕度：工作电流应低于 Isat，推荐在额定电流以下留 10–30% 余量，避免在高温或老化条件下发生饱和。
- 损耗与发热：结合 DCR 与实际平均直流电流评估功耗 Pd = I^2 × DCR，并考虑散热与温升。
- 纹波电流：设计开关电源时按规范计算电感纹波 ΔI，确认峰值电流不超过 Isat。
- 封装与版图：6×6mm 占板面积小，但需保证焊盘与热量散布合理，遵循制造商推荐的 PCB footprint 与回流工艺。
五、可靠性与装配注意事项
- 建议按标准回流焊工艺进行贴装，避免手工高温焊接导致结构损伤。
- 若长期存放，请按电子元件存储规范防潮防尘；若包装显示需烘烤处理请按 MSL 要求处理。
- 工作环境注意温度与电流双重应力，必要时进行老化与热循环测试验证设计裕度。
六、总结
FNR6045S220MT 以 22µH/2A 的电气参数与磁胶屏蔽 SMD 结构，提供了对体积、可靠性与电磁兼容有综合要求的中小功率电源解决方案。选型时关注电流裕量、DCR 带来的功耗与 PCB 散热设计，可在消费电子、通信与工业控制等领域实现稳定应用。若需更详细的电气特性曲线、温升数据或封装图纸，建议联系长江微电获取完整规格书与应用资料。

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.
