FTC252010S4R7MBCD 产品概述

一、产品简介

FTC252010S4R7MBCD 为长江微电(cjiang)推出的一款表面贴装功率电感,标称电感值 4.7 μH,允许偏差 ±20%,定位于中小功率开关电源和电源滤波场合。器件额定电流 2.0 A,饱和电流(Isat)2.6 A,直流电阻(DCR)145 mΩ,封装标识为 1008,适合对体积与性能都有一定平衡要求的应用。

二、主要参数(典型)

  • 电感值:4.7 μH(±20%)
  • 额定电流:2.0 A
  • 饱和电流(Isat):2.6 A(在该电流水平下电感明显下降)
  • 直流电阻(DCR):约 145 mΩ
  • 封装:1008
  • 品牌:cjiang(长江微电)

三、特点与优势

  • 稳定的电感值与宽容差,适合常见开关频率下的滤波与储能需求。
  • 较高的饱和电流保证在瞬态大电流时不易失磁,适用于短时过载或启动冲击。
  • 相对较低的成本与标准化封装,便于批量采购与贴片生产。
  • 封装适中,可较方便地布局在开关电源的输入/输出滤波位置。

四、典型应用场景

  • 同步/非同步降压(Buck)稳压器的储能电感与输出滤波。
  • 开关电源、DC-DC 模块、车载电源(符合其电流与温升条件时)。
  • 电源输入滤波、EMI 抑制与直流链路噪声抑制。
  • 工业控制、通信设备、消费电子小功率电源模块。

五、使用与选型建议

  • 电流余量:建议长期工作电流不超过额定电流的 70%–85%(约 1.4–1.7 A),以降低温升并延长寿命;若工作环境温度较高需进一步降额。
  • 饱和裕量:若电路存在较大瞬态电流,应确保峰值电流明显低于 Isat(2.6 A),以避免电感值急剧下降影响输出稳定性。
  • 损耗评估:直流损耗近似为 P = I^2·DCR,满额定电流时(2 A)损耗约 0.58 W,需评估器件及周边散热条件。
  • 滤波设计:在切换频率已知时,通过 ΔI = V/(L·f) 计算纹波电流,确认电感值能满足纹波要求,或调整电容与开关频率配合。
  • 测量与验证:建议在目标 PCB 上测量实际电感值和温升,确认在实际工作频率和电流下性能符合预期。

六、封装与可靠性注意事项

  • 1008 封装需注意焊盘设计与热回流工艺,控制回流曲线以避免卸磁或机械应力。
  • 布局时尽量靠近功率开关或输出端,减小环路面积以降低 EMI。
  • 长期使用应考虑环境温度、潮湿与振动,按实际应用做必要的可靠性测试(温升、热循环、振动、焊接可靠性)。

七、检验与试验要点

  • 常用项目:静态电感值测量(规定频率)、DCR 测试、饱和电流测试、温升试验和纹波电流下的等效电感测量。
  • 关注点:在接近额定电流时的温升、超过 Isat 时电感衰减情况、以及在开关频率工作点处的频率特性。

总结:FTC252010S4R7MBCD 为一款适用于中小功率电源的表贴功率电感,参数组合(4.7 μH、2 A、Isat 2.6 A、DCR 145 mΩ)使其在通用 DC-DC、滤波与 EMI 抑制场景中具有较好的实用性。但使用时应重视电流降额与散热管理,必要时在系统级进行实测以确认满足可靠性与效率要求。

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.
