FTC303020D3R3MBCA 功率电感产品概述

一、产品核心定位与基本参数

FTC303020D3R3MBCA是长江微电(cjiang) 推出的小型化贴片功率电感,专为中等功率密度的电源转换场景设计,核心参数清晰明确:

  • 电感值:3.3μH(精度±20%,满足通用电源电路需求);
  • 额定电流(Irms):4.5A(连续工作时电感温升≤40K,符合行业标准);
  • 饱和电流(Isat):5.9A(电感值下降30%时的峰值电流,应对瞬间浪涌);
  • 直流电阻(DCR):52mΩ(典型值,低损耗设计提升效率);
  • 封装规格:SMD贴片式,尺寸3×3×2mm(长宽高,适配轻薄化设备);
  • 环保认证:符合RoHS无铅要求,可用于出口类产品。

二、性能优势与设计亮点

该电感针对电源电路的效率、可靠性与小型化需求,具备以下核心优势:

  1. 低损耗降低热耗:52mΩ的低DCR可减少连续工作时的热损耗,在35A负载区间能将DC-DC转换器效率提升约2%3%,尤其适合对续航敏感的移动设备;
  2. 电流承载能力适配主流场景:4.5A额定电流覆盖手机CPU、IoT网关等主流芯片的供电需求,5.9A饱和电流可应对电路启动浪涌(如电容充电瞬间),避免电感饱和导致的电压波动;
  3. 小型化封装适配轻薄化趋势:3×3mm的紧凑尺寸可节省PCB空间,支持自动化贴片生产,同时兼容主流贴片机的精度要求;
  4. 宽温可靠性覆盖极端场景:采用耐高温磁芯与绕组材料,工作温度范围为**-40℃~+125℃**,可适应车载低温启动、工业设备高温运行等环境。

三、典型应用场景

FTC303020D3R3MBCA广泛适用于以下中等功率电源转换场景:

  1. 移动智能终端:手机、平板、智能手表的CPU/内存供电DC-DC降压模块,适配设备轻薄化设计;
  2. IoT终端设备:智能手环、智能家居传感器、工业无线模块的低功耗DC-DC升压/降压电路,低DCR提升待机续航;
  3. 小型家电控制板:智能插座、加湿器、扫地机器人的电源转换模块,宽温范围适配家电使用环境;
  4. 汽车电子辅助电路:车载USB充电接口、仪表盘背光电源、倒车雷达控制模块的低功率供电电路,抗振动性能满足MIL-STD-202振动测试标准。

四、封装与可靠性说明

  1. 封装特性:采用SMD贴片封装,引脚间距符合IPC标准,支持回流焊(峰值温度260℃±5℃)、波峰焊等工艺,焊接兼容性强;
  2. 可靠性测试验证:
    • 振动测试:10~2000Hz频率范围,加速度1.5g,测试后电感性能衰减≤1%;
    • 耐温循环测试:-40℃~+125℃循环1000小时,电感值变化率≤±5%;
    • 耐湿测试:85℃/85%RH环境下1000小时,DCR变化率≤±10%。

五、选型参考与使用注意事项

  1. 选型匹配建议:
    • 若需更高电流(6A以上),可参考同系列FTC303020D4R7MBCA(4.7μH)或FTC303020D6R8MBCA(6.8μH);
    • 若需更高精度(±10%),需确认长江微电同系列高精度型号;
  2. 使用注意事项:
    • 连续工作电流需控制在4.5A以内,避免温升过高导致磁芯老化;
    • 峰值电流不得超过5.9A,否则电感值下降会引发DC-DC输出不稳定;
    • 焊接时遵循IPC-A-610标准,避免过焊或虚焊影响可靠性。

该产品凭借“小尺寸+高电流+低损耗”的综合优势,成为移动设备、IoT终端等场景的高性价比功率电感选择。

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
