FHD252010S-4R7MT功率电感产品概述

一、产品基本定位

FHD252010S-4R7MT是长江微电(cjiang)推出的贴片式中小功率电感,针对高密度电子电路设计,兼顾性能稳定性与成本优势,适用于消费电子、物联网模块、小型工业控制等场景,是开关电源、滤波电路的常用基础元件。

二、核心电性能参数详解

该电感的核心参数直接决定适用场景,需结合电路需求重点关注:

  1. 电感值与精度:标称4.7μH,精度±20%(实际范围3.76μH~5.64μH),满足多数开关电源、EMI滤波的电感量要求;
  2. 额定电流:1.1A(直流),指环境温度≤85℃时,长期连续工作且电感值变化≤10%、温升≤40℃的最大电流,是电路连续负载的核心参考;
  3. 饱和电流:1.5A(直流),定义为电感值降至标称值80%(3.76μH)时的电流,是峰值负载极限——若超过该值,电感储能能力骤降,可能引发电源纹波超标、电路不稳定;
  4. 直流电阻(DCR):255mΩ(典型值),反映绕组直流损耗,低DCR可降低功率消耗,提升便携式设备的续航效率。

三、封装与物理特性

  1. 封装尺寸:SMD贴片封装,型号“1008”为英制标注(100mil×80mil),对应公制尺寸约2.54mm×2.03mm×1.0mm(厚度),体积小巧,可节省PCB空间;
  2. 工艺结构:采用铁氧体磁芯绕线工艺,磁芯具备低损耗、高饱和特性,适配高频开关电路;
  3. 环保认证:符合RoHS 2.0、REACH标准,无铅焊接,适配现代电子制造的环保要求。

四、品牌与可靠性说明

长江微电(cjiang)是国内电感领域的成熟制造商,产品覆盖消费电子、汽车电子等领域。FHD252010S-4R7MT经过多项可靠性测试:

  • 温湿度循环(-40℃85℃,5%95%RH);
  • 振动测试(10~2000Hz,加速度2g);
  • 冲击测试(1500g峰值加速度,持续0.5ms);
    可靠性符合GB/T 2693-2001行业标准,可满足多数场景的长期稳定需求。

五、典型应用场景

该电感因体积小、电流适配性强,常见应用包括:

  1. 便携式设备电源:手机、平板的DC-DC降压/升压电路(如5V转3.3V);
  2. LED驱动:小功率LED灯带、台灯的恒流/恒压驱动电路;
  3. 物联网模块:WiFi、蓝牙模块的电源滤波与储能;
  4. 小型家电控制:智能插座、加湿器的开关电源电路;
  5. 工业辅助电路:小型PLC、传感器模块的辅助电源。

六、选型与使用注意事项

  1. 电流余量:连续工作电流需低于额定电流(建议留20%~30%余量),避免长期过热衰减性能;
  2. 峰值控制:峰值负载不得超过1.5A饱和电流,防止电感饱和引发纹波超标;
  3. 温度降额:环境温度>85℃时,需按降额曲线降低允许电流(通常每升高10℃降额10%);
  4. PCB布局:靠近开关管、输出电容布局,缩短走线长度,减少寄生电感与EMI干扰。

该电感凭借紧凑体积、稳定性能,成为中小功率电路的高性价比选择,可覆盖多数常规电子设备的电感需求。

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
