FNR6045S150MT 产品概述

FNR6045S150MT 是长江微电(cjiang)推出的一款磁胶屏蔽功率电感,额定电感量为 15 μH(±20%)。器件采用 SMD 封装、6×6 mm 规格,针对空间受限且需稳定电流供给的开关电源与滤波场合优化设计,兼顾较低直流电阻与良好的饱和电流性能,适合中功率 DC-DC 转换器和电源滤波应用。

一、主要参数一览

  • 型号:FNR6045S150MT
  • 品牌:cjiang(长江微电)
  • 电感值:15 μH ±20%
  • 额定电流(Irated):2.2 A(连续工作参考)
  • 饱和电流(Isat):2.7 A(电感下降明显前的临界点)
  • 直流电阻(DCR):约 88 mΩ
  • 类型:磁胶屏蔽电感(屏蔽式功率电感)
  • 封装:SMD,外形尺寸约 6 × 6 mm

二、结构与特性

FNR6045S150MT 采用磁胶屏蔽结构,在保证高电流承载能力的同时,有效抑制磁通外泄与电磁干扰,利于 EMI 管理与电路密集布局。主要特性包括:

  • 屏蔽效果好:降低对周边敏感器件的磁干扰。
  • 高饱和电流:2.7 A 的 Isat 使其在瞬态或峰值电流较高时仍能维持相对稳定的工作。
  • 低 DCR:88 mΩ 的直流电阻有助于减小功耗与温升,提升转换效率。
  • 封装适配表面贴装工艺,适合自动化回流焊与高密度 PCB 设计。

三、典型应用场景

  • 开关稳压器(开关电源、降压转换器 / buck)
  • 电源滤波器(输入输出滤波与去耦)
  • 电池供电设备的能量管理模块
  • 工业与通信设备中需要中等电流滤波的功率路径
    由于额定电流为 2.2 A,该器件适用于中等功率等级的电源设计;在存在短时高峰值电流的场合,2.7 A 的饱和电流提供一定裕量,但不建议长期超过额定值工作。

四、选型与使用建议

  • 电流裕量:实际电路中应以最大连续工作电流不超过 Irated 为目标,若负载或瞬态电流接近或超过 2.2 A,应考虑更高额定电流的器件或设计足够的热/电流裕度。
  • 饱和注意:Isat 为磁芯饱和前的临界值,超过此值电感量会急剧下降,可能导致滤波或输出纹波恶化。
  • DCR 与效率:88 mΩ 的直流电阻在中等电流下会带来一定 I^2R 损耗,应在热设计与效率预算中考虑。
  • 布局建议:电感与开关器件、输入/输出电容尽量靠近布置以缩小回流环路,减小 EMI;若对散热敏感,可在器件下方或附近安排铜箔散热路径与过孔。
  • 焊接兼容性:适配常规 SMD 回流焊流程,建议遵循厂商回流温度曲线与焊盘建议以确保可靠性(如有具体工艺要求,请参照供应商资料)。

五、总结

FNR6045S150MT 是一款面向中等电流功率路径的 15 μH 磁胶屏蔽 SMD 电感,兼顾屏蔽性能与较低 DCR,适合用于降压转换器、功率滤波与电源管理模块。设计时应充分考虑额定电流与饱和电流之间的裕量、DCR 带来的能量损耗以及 PCB 布局对 EMI 与散热的影响,以保证长期稳定可靠运行。如需更高电流或更低 DCR 的方案,可联系供应商获取系列替代型号与详细数据手册。

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
