YSMC0430V-4R7M 一体成型功率电感产品概述

一、产品定位与核心特性

YSMC0430V-4R7M是益嘉源(YJYCOIN)针对中小功率电源电路设计的表贴一体成型功率电感,核心定位为开关电源、DC-DC转换器的储能与滤波元件。其关键特性包括:

  1. 一体成型磁芯优势:无气隙设计降低电磁干扰(EMI),同时提升抗振动、抗冲击能力,适配工业控制、消费电子等可靠性要求较高的场景;
  2. 高电流密度:饱和电流(Isat)达4.4A,满足中小功率电源的输出电流需求;
  3. 低损耗设计:直流电阻(DCR)仅31.5mΩ,减少导通损耗,提升电源转换效率;
  4. 小体积适配:4×4×3mm表贴封装,节省PCB空间,适配小型化电子设备(如笔记本、LED驱动)。

二、关键电气参数解析

参数是产品应用的核心依据,以下为核心参数的实际意义:

  1. 电感值:4.7uH ±20%
    电感量决定储能能力,4.7uH适配100kHz~1MHz频段的开关电源(如笔记本电源、LED驱动);±20%精度满足常规电源的设计容差,无需额外高精度匹配。
  2. 饱和电流(Isat):4.4A
    Isat定义为电感值下降30%时的电流,是避免饱和的关键指标。实际工作电流建议控制在Isat的70%80%(即3.1A3.5A以内),可防止电感饱和导致输出电压波动、效率下降。
  3. 直流电阻(DCR):31.5mΩ
    DCR直接影响功耗(P=I²×R),31.5mΩ的低阻值可将3A电流下的损耗控制在约280mW,减少电源发热,提升整体效率。

三、封装与物理特性

产品采用SMD表贴封装,物理参数适配自动化生产与小型化设计:

  • 尺寸:4.0mm(长)×4.0mm(宽)×3.0mm(高),符合行业“0430”封装规格(长度×宽度×高度,单位mm);
  • 引脚:标准SMD焊盘,焊接可靠性高,适配回流焊、波峰焊工艺;
  • 工作温度:-40℃~+125℃(一体成型电感常规温区,满足宽温环境应用);
  • 机械强度:一体成型结构无松散绕线,可承受10G以上振动(参考品牌 datasheet 常规值),适合车载、工业控制等振动场景。

四、典型应用场景

结合参数特性,产品主要适用于以下场景:

  1. 中小功率DC-DC转换器:如5V转3.3V/3A、12V转5V/2A电路,适配笔记本电脑、平板电脑电源模块;
  2. LED驱动电源:小功率LED灯带、显示屏背光驱动,配合开关管实现恒流输出;
  3. 消费电子控制板:智能电视、路由器、机顶盒的电源滤波与储能;
  4. 工业控制电路:小型PLC、传感器模块的电源电路,适配宽温与振动环境。

五、选型与使用注意事项

为保证性能与可靠性,需注意以下要点:

  1. 电流匹配:实际工作电流≤Isat的80%,若负载接近4A,建议并联两只电感或选择更高Isat型号;
  2. PCB布局:电感靠近开关管与输出电容,缩短电流路径减少EMI;避免与高频信号线平行布线;
  3. 散热设计:焊盘面积≥5mm²,PCB背面布置散热铜箔,降低大电流下的温度;
  4. 焊接工艺:回流焊峰值温度≤260℃,回流时间≤10秒;禁止手工焊接过热损坏磁芯。

该产品以“高可靠性、低损耗、小体积”为核心优势,可满足中小功率电源电路的多样化需求,是消费电子、工业控制领域的实用选型。

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
