FNR5020S330MT — 33µH 磁胶屏蔽功率电感产品概述

一、产品简介

FNR5020S330MT 为长江微电(cjiang)出品的一款 SMD 型磁胶屏蔽功率电感,封装尺寸约 5×5mm,针对空间受限的电源滤波与能量储存场合优化设计。标称电感值 33µH,允许偏差 ±20%,适用于低至中等电流的开关电源与电源管理电路。

二、关键电气参数

  • 电感值:33µH ±20%
  • 额定电流:990mA(连续工作参考值)
  • 饱和电流(Isat):1A(在此电流附近电感值显著下降)
  • 直流电阻(DCR):约 507mΩ
  • 类型:磁胶屏蔽电感(屏蔽结构,有利于减少磁通泄漏和相邻器件干扰)
  • 封装:SMD,外形约 5×5mm,便于自动贴装与回流焊工艺

三、主要特性与优势

  • 小尺寸、大功率密度:5×5mm 的贴片封装适合空间受限板面,在有限面积内提供较高能量储存能力。
  • 良好屏蔽性能:磁胶屏蔽结构能降低磁场外泄,对贴近敏感信号线或高密度布局有利。
  • 可靠的电流处理能力:额定电流接近 1A,满足多数便携式设备、LED 驱动与中小功率 DC-DC 模块的需求。
  • 稳定性与重复性:适配 SMT 自动化生产,DCR 与电感值经过生产控制,利于批量一致性。

四、典型应用场景

  • 降压/升压 DC-DC 转换器(电源输出滤波与能量传输)
  • 电源滤波(输入侧或输出侧 EMI/RFI 抑制)
  • LED 驱动电源、充电器与便携式设备供电模块
  • 工业控制与通信终端的局部电源管理

五、使用建议与注意事项

  • 工作电流选择:建议在额定电流以下工作并预留裕量,避免长期接近 Isat 以免电感值急剧下降或发热上升。
  • 温升与散热:DCR 较高时会带来较大功耗(I^2·R),在高电流场合需关注温升与周边元件温度影响。
  • 焊接与PCB布局:支持无铅回流焊工艺,建议按照厂方推荐的焊盘尺寸与回流曲线焊接;入板时注意尽量缩短与电源开关元件的走线并做好地层与散热设计。
  • 储存与搬运:避免潮湿与高温环境,贴片卷盘应在规定条件下储存并按 MSDS / 工厂包装要求处理。

六、质量与选型参考

FNR5020S330MT 提供了在中小电流电源应用中可靠的电感值与磁场屏蔽效果。在选型时应结合实际工作频率、纹波电流、允许电阻损耗及温升要求,评估是否需选择更低 DCR 或更高额定电流的型号。如需更准确的 PCB 焊盘尺寸、回流焊温度曲线或频率相关的电感特性曲线,请联系长江微电索取完整数据手册。

七、订购信息

型号:FNR5020S330MT
品牌:cjiang(长江微电)
封装形式:SMD,5×5mm 尺寸级别
典型用途:功率滤波与 DC-DC 储能元件

如需样品测试或批量采购建议与供应商确认最终规格与可靠性验证要求,以保证在目标应用中的长期稳定性与一致性。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
