FNR6045S360MT 产品概述

一、产品简介

FNR6045S360MT 是长江微电(cjiang)推出的一款功率电感,封装为贴片式(SMD),外形尺寸约 6 × 6 mm,属于磁胶屏蔽电感。该器件专为开关电源与电源管理场合设计,在体积受限的电路板上提供能量储存与滤波功能,同时降低外泄磁通与电磁干扰。

二、主要性能参数

  • 标称电感值:36 μH(公差 ±20%,实际范围约 28.8 μH ~ 43.2 μH)
  • 额定电流:1.5 A(连续额定)
  • 饱和电流(Isat):1.8 A(磁通密度导致电感下降但仍可工作)
  • 直流电阻(DCR):225 mΩ
  • 类型:磁胶屏蔽电感(屏蔽性好、漏磁小)
  • 封装:SMD,6 × 6 mm(适合自动贴装)

三、性能特点与优势

  • 小型化:6×6 mm 紧凑封装,利于高密度布板与体积受限产品的应用。
  • 屏蔽性好:磁胶屏蔽结构有效控制外泄磁通,降低对周围敏感元件的干扰。
  • 适用高频开关:针对开关电源等动态工作环境优化,支持开关转换场合的能量传输与滤波。
  • 明确电流极限:1.5 A 连续额定、1.8 A 饱和,为系统设计提供清晰的安全余量。

四、典型应用场景

  • 各类 DC-DC 降压/升压转换器(buck/boost)
  • 模组电源滤波与储能回路
  • LED 驱动电源与便携设备电源管理
  • 电池充放电管理、工业控制电源前端滤波
  • 需要低漏磁、低 EMI 的开关电源设计

五、设计与选型建议

  • 电流余量:建议在连续工作情况下对额定电流进行降额(例如取额定电流的 70%~80%),以降低温升与磁芯退磁风险。
  • 温升与功耗估算:按 DCR 计算铜损 P = I^2 × DCR;在额定电流 1.5 A 下,P ≈ 0.51 W,需考虑散热与周边元件温度上升。
  • 饱和裕量:若电路可能出现短时大电流脉冲,注意不要超过 Isat = 1.8 A,以免电感值显著下降影响稳定性。
  • 电感公差:±20% 的公差在精密滤波或谐振回路中需预留空间,必要时在选型时考虑更精确的器件或配合调整元件参数。

六、焊接与可靠性注意事项

  • 适用回流焊工艺,遵循厂商推荐的回流温度曲线以避免器件热应力。
  • 贴装时注意端子与焊盘的良好热量传导,保证焊点完整以减少接触电阻与寄生热源。
  • 在高振动或机械冲击环境中,合理固定并留意基板应力分布,防止封装开裂或引脚脱落。

七、包装与订购

  • 封装方式:SMD 卷带包装,适合自动贴片机使用(具体包装规格与最小订购量请联系供应商确认)。
  • 型号与品牌:FNR6045S360MT,品牌 cjiang(长江微电)。如需电气参数的样片测试、器件曲线或更详细的封装图,请向供应商索取完整数据手册。

总结:FNR6045S360MT 以其 36 μH 的电感值、紧凑的 6×6 mm SMD 封装及良好的屏蔽特性,适用于多种中低功率开关电源与滤波场合。设计时应关注电流降额、铜损带来的温升及电感公差对电路性能的影响。若对频率特性、温升试验或可靠性有进一步要求,建议结合实测数据进行最终验证。

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
