产品概述

FNR6028S330MT 产品概述

一、产品简介

FNR6028S330MT 是长江微电（cjiang）推出的一款磁胶屏蔽功率电感，标称电感值为 33 μH，公差 ±20%，为表面贴装（SMD）封装，外形约为 6×6 mm。该器件专为中小电流开关电源、滤波与储能应用设计，具有良好的电流处理能力与磁屏蔽性能，适合 PCB 密集布线环境。

二、主要参数

电感值：33 μH ±20%
额定电流（Ir）：1.3 A（持续工作电流建议在此值以下）
饱和电流（Isat）：1.5 A（超过该值电感量显著下降）
直流电阻（DCR）：241 mΩ
类型：磁胶屏蔽电感（屏蔽性能有助于降低对周围元件的磁干扰）
封装：SMD，尺寸约 6×6 mm
品牌：cjiang（长江微电）

三、性能要点与使用建议

功率损耗：在额定电流 1.3 A 下，DCR 导致的 I^2R 损耗约为 0.41 W（1.3^2×0.241）；在短时峰值 1.5 A 下损耗约为 0.54 W。设计时需考虑温升与散热空间。
饱和与直流偏置：实际工作中直流偏置与纹波电流会使有效电感下降，建议设计留有裕量，连续工作电流按 70%–80% 的额定值考虑可提高可靠性。
噪声与屏蔽：磁胶屏蔽结构在减小漏磁和抑制 EMI 上有优势，适合对电磁干扰敏感的应用场景。
测试与选型：请根据目标频率和纹波电流核查实际电感在工作点（有直流偏置）下的变化，必要时向厂商索取电感随电流/频率变化曲线。

四、典型应用

适用于降压（Buck）转换器输出滤波、电源输入滤波、LED 驱动、电池管理系统、便携设备与其他对体积与屏蔽有要求的开关电源场合。

五、封装与安装注意

推荐采用标准回流焊工艺，遵循 IPC 焊接规范与厂商提供的回流温度曲线。
PCB 布局时应保证电感周围有适当散热区域，避免热源直接邻近；焊盘尺寸与过孔布局应根据供应商推荐封装尺寸设计，以保证可靠焊接与机械强度。
长期高温或过流会加速性能退化，设计时应考虑环境温度、散热和电流裕量。

如需更详细的电感随频率/直流偏置曲线、封装图或回流曲线，请向供应商索取完整数据手册。
