FNR6028S560MT 产品概述

一、产品简介

FNR6028S560MT 是长江微电(cjiang)推出的一款磁胶屏蔽功率电感,额定电流 1A,标称电感值 56μH(公差 ±20%),饱和电流 Isat 为 1.2A,直流电阻 DCR 为 449mΩ。器件为 SMD 贴片封装,外形尺寸约 6×6mm,适合自动贴装与回流焊工艺。该器件定位为小型化功率电感,用于电源滤波与能量储存场合,兼顾屏蔽与磁耦合抑制。

二、主要电气参数

  • 电感值:56 μH,公差 ±20%(实际范围约 44.8μH — 67.2μH)
  • 额定电流:1.0 A(连续导通时推荐不超额定值)
  • 饱和电流(Isat):1.2 A(接近该值时电感量会明显下降)
  • 直流电阻(DCR):449 mΩ(0.449 Ω)
  • 封装形式:SMD,尺寸约 6×6 mm
  • 类型:磁胶屏蔽电感(屏蔽设计有利于减少对周围元件的干扰)

三、性能特点

  • 小体积、高电感:6×6mm 的表面贴装封装能在有限空间内提供 56μH 的电感量,适合紧凑型电源模块。
  • 屏蔽结构:磁胶屏蔽设计可降低磁通外泄,减小对附近敏感电路的干扰,利于多器件密集布局。
  • 良好的自动化装配兼容性:SMD 封装适配常见贴装机与回流焊流程。
  • 注意 DCR 较高:449mΩ 的直流电阻意味着在 1A 工作电流时 I^2·R 损耗约 0.449W,应重视发热与效率影响,适用于对效率要求不极端苛刻且电流较小的场合。

四、典型应用场景

  • 低功率 DC-DC 降压/升压模块的输出滤波或能量储存元件;
  • 音频电源、便携式设备电源滤波;
  • EMI 滤波与电源去耦场合,尤其需要屏蔽效果时;
  • 电池管理与充电电路中对大电流要求不高的滤波用途。

五、选型与使用建议

  • 电流余量:为避免磁芯接近饱和并减少温升,建议实际连续工作电流优先保持在额定电流以下(例如 ≤0.8A),并避免长时间接近 Isat。
  • 效率考量:若系统对效率要求严格或电流显著大于 1A,应考虑 DCR 更低的功率电感以降低 I^2R 损耗。
  • 温升与散热:由于 DCR 会产生热量,布局时应为电感留有合理散热空间,且避免与热敏器件紧邻。
  • 电感容差:±20% 的公差在精密滤波或谐振回路中需预留容差设计。
  • 饱和特性:应用于脉冲较大或瞬态电流场合前,应验证在峰值电流下的电感降额对电路性能的影响。

六、封装、焊接与储存注意事项

  • 焊接:建议遵循厂商推荐的回流温度曲线与焊膏用量,避免过高峰值温度或过长高温保温时间导致性能退化。
  • 防潮与存储:SMD 元件应按贴片元件的常规防潮要求储存,开盘后在规定时间内使用并妥善回潮处理。
  • 安装与清洁:贴装时避免机械冲击,清洗时使用对磁性材料安全的清洗剂,避免强酸强碱侵蚀。

总结:FNR6028S560MT 为一款面向小型化电源滤波与低功率能量储存场合的磁胶屏蔽功率电感,适合空间受限且对屏蔽有要求的设计。选型时需权衡其较高的 DCR 与电流能力,对系统热管理与效率指标进行验证,以确保可靠运行。

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
