FNR6020S2R0NT 产品概述
一、产品简介
FNR6020S2R0NT 是长江微电（cjiang）推出的一款功率型贴片磁胶屏蔽电感，适用于中高电流的开关电源与电源滤波场合。电感量为 2 μH，封装为 SMD，外形尺寸 6×6 mm，结合较低的直流电阻与较高的饱和电流，能在紧凑空间内提供稳定的储能与滤波性能。
二、主要性能参数
- 电感值：2.0 μH（±30%）
- 额定电流（Ir）：3.3 A
- 饱和电流（Isat）：4.9 A（磁芯开始饱和时的电流）
- 直流电阻（DCR）：约 46 mΩ
- 类型：磁胶屏蔽电感（屏蔽化封装，减小磁通泄漏）
- 封装：SMD，尺寸 6×6 mm
三、功能特点
- 高电流能力：额定电流 3.3 A，饱和电流 4.9 A，适合用于输出滤波或能量储存要求较高的电源回路。
- 低 DCR：约 46 mΩ，有利于降低功率损耗与发热，提高转换效率。
- 屏蔽结构：磁胶屏蔽设计可有效抑制磁场外围泄漏，便于与其他敏感器件并列布局。
- 紧凑封装：6×6 mm SMD 形式，适合高密度 PCB 设计和自动化装配。
四、典型应用场景
- 同步降压/升压转换器的输出电感与输入滤波元件；
- 电源模块与板载电源（POL）应用；
- 工业电源、通信设备、消费类电子中要求中等至高电流滤波与储能的场合；
- 需要屏蔽以降低电磁干扰的紧凑型电源设计。
五、选型与使用建议
- 留有裕量：在稳态选型时，建议工作电流不超过额定电流 3.3 A，以避免长期过热；瞬态峰值电流应低于 Isat（4.9 A）以防止电感饱和。
- 考虑损耗：DCR 46 mΩ 会在大电流下产生一定的 I^2R 损耗与发热，设计时需评估散热与温升对性能的影响。
- 布局注意：将电感靠近电源开关或输出端放置，减小回流环面积；屏蔽结构有助于降低对周围器件的干扰，但仍应保持合理间距。
- 焊接工艺：适用于常规 SMD 回流焊工艺，建议按制造商提供的回流曲线进行焊接，避免超过推荐的温度/时间限制以保护磁胶结构。
六、可靠性与测试要点
- 测量电感值时，应在实际工况或接近开关频率下测试，以反映工作状态下的有效电感。
- 大电流测试需关注温升与 DCR 随温度变化的影响；长期循环应评估磁芯稳定性与机械强度。
- 若用于高脉冲或高纹波电流环境，应验证在对应脉冲下是否发生局部磁饱和或性能退化。
七、小结
FNR6020S2R0NT（长江微电 cjiang）是一款面向中高电流电源设计的 2 μH 屏蔽功率电感，具备较高的饱和电流与较低的直流电阻，适合开关电源输出滤波与能量储存等场合。在选型与布局时注意电流裕量、散热与焊接工艺，可以在保证性能的前提下实现高密度、低干扰的电源解决方案。若需更详尽的环境温度范围、频率特性或回流曲线，请联系供应商获取完整数据手册。

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.
