FHD201610S-4R7MT 产品概述

一、产品简介

FHD201610S-4R7MT 是长江微电(cjiang)推出的一款表面贴装功率电感,封装规格为 0806(公制 2016),专为开关电源与电源管理模块中的能量储存与滤波设计。该器件体积小、耐电流能力适中,适用于空间受限的消费类电子与工业类电源前端滤波场合。

二、主要参数

  • 电感值:4.7 µH ±20%
  • 额定电流(Irms):1.0 A(连续工作参考)
  • 饱和电流(Isat,磁通降至初始电感的指定百分点时):1.4 A
  • 直流电阻(DCR):约 370 mΩ
  • 封装:SMD 0806(2016)
    注:更详细的温度、频率特性及耐压等参数请以厂方数据手册为准。

三、性能特点

  • 小型化封装,便于高密度 PCB 布局。
  • 适度饱和电流,能够承受瞬态冲击电流;在额定电流附近保持较稳定的电感值。
  • 较高的 DCR 表明在高电流工作时有一定损耗,适合中低功率应用场景。

四、典型应用场景

  • 便携设备与消费电子的降压(Buck)转换器输出滤波。
  • 输入侧/输出侧的电源滤波与共模抑制(配合电容形成 LC 滤波)。
  • 驱动电路与模块化电源解决方案中作为能量储存元件。

五、设计与使用建议

  • 电流选型:长期工作电流建议不超过额定 1.0 A,若存在较大突发电流应保证不超过饱和电流 1.4 A,并留有充分余量以避免电感饱和引起性能急剧下降。
  • 热管理:DCR 较高会带来较明显的功耗(Pd = I^2·DCR),需关注 PCB 散热与周围器件的热影响,必要时选择更大封装或并联方案。
  • 布局建议:将电感尽量靠近开关器件或负载端,输入/输出电容与电感尽量短且宽的回流路径,减小寄生电感与 EMI。
  • 测试验证:在目标频段下验证电感随频率与 DC 偏置的变化,评估滤波效果与开关噪声抑制。

六、选型要点

选择时优先考虑实际工作电流、允许的功率损耗与尺寸限制。若长期平均电流接近或超过 1 A,建议选用 DCR 更低或饱和电流更高的型号;对噪声敏感的应用则需结合电容、布局与磁屏蔽一并优化。

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
