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。

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
