FNR6045S820MT — 82µH 磁胶屏蔽功率电感 产品概述
一、产品简介
FNR6045S820MT 是长江微电（cjiang）出品的一款表面贴装磁胶屏蔽功率电感，标称电感量 82µH（±20%），适用于中低功率开关电源滤波与电源管理电路。器件采用 6×6mm SMD 封装，结构为磁胶屏蔽设计，有利于减小外泄磁场和抗干扰能力。
二、主要电气参数
- 电感值：82µH，公差 ±20%
- 额定电流（Irated）：990mA（持续允许工作电流，受温升限制）
- 饱和电流（Isat）：1.1A（电感下降到额定值的一定比例时的参考值）
- 直流电阻（DCR）：443mΩ（影响功率损耗与效率）
- 封装形式：SMD，尺寸 6.0 × 6.0 mm
- 类型：磁胶屏蔽电感 / 功率电感
三、产品特点
- 磁胶（复合磁粉）材料与屏蔽结构，兼顾较高电感值与良好磁屏蔽性能；
- 中等电流等级（~1A），适合小型化电源模块与电流路径需求不大的应用；
- 较高的 DCR 意味在较大电流下会产生显著铜耗，设计时需考虑效率与发热；
- SMD 封装适配自动贴装与回流焊工艺，便于批量生产与组装。
四、典型应用场景
- 小功率 DC-DC 降压/升压转换器（如便携设备辅助电源）；
- 电源输入滤波与输出纹波抑制；
- EMI/射频干扰滤波；
- 工业控制与车载电子中对空间与屏蔽有要求的电源模块。
五、选型与使用建议
- 电流留余量：建议工作电流在额定电流以下，通常留 10–30% 余量以避免接近饱和和过热；
- 饱和余量：若电路可能出现短时冲击电流或较大纹波，应验证在实际峰值电流下电感不会进入深度饱和；
- 效率与 DCR：443mΩ 的 DCR 在近安培电流下会产生明显功耗（P = I^2·R），需在系统热管理与能效预算中考虑；
- 布局与散热：尽量缩短与电感相连的走线，确保良好焊盘接触，散热铜箔与地平面可帮助降低温升；
- 焊接工艺：遵循厂家回流焊温度曲线，避免长期高温储存或重复热循环影响性能。
六、可靠性与包装
长江微电的功率电感通常符合一般电子元器件的可靠性测试（回流焊、耐湿热、机械振动等）。出货时常见卷带包装（可选盘带），便于 SMT 贴装。选购时应向供应商确认是否满足 RoHS 等环保和客户特定的认证要求。
七、注意事项
- 如需在较高频率下使用，请评估器件的频率响应与实际电感值随频率变化的特性；
- 对于关键电源路径，建议在样机上进行电流-温升与电感饱和测试，确认长期可靠性；
- 若系统对效率或体积有更高要求，可比较同系列中低 DCR 或更高电流等级的型号。
综上，FNR6045S820MT（82µH，≈1A 级）适合追求良好磁屏蔽与中等电感量的小型电源应用，但在高效率或大电流场合需谨慎评估 DCR 与饱和特性。若需要更详细的频率特性曲线、温升数据或封装引脚图，请提供具体需求以便获取厂家数据手册。

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.
