YSPI1050-470M 一体成型功率电感产品概述

YSPI1050-470M是益嘉源(YJYCOIN) 推出的一款SMD贴片式一体成型功率电感,专为中功率电源电路的储能、滤波及EMI抑制需求设计,兼具高可靠性、低损耗与紧凑体积,适用于消费电子、工业控制、车载电子等多领域。

一、产品核心定位与工艺类型

YSPI1050-470M属于一体成型功率电感,区别于传统绕线电感的磁芯分离结构,采用“绕组+磁芯”一体化压制工艺:通过高温高压将磁粉与绕组紧密结合,消除磁芯间隙,既提升结构稳定性,又降低电磁辐射干扰(EMI)。作为贴片器件,其无引脚设计适配自动化贴装产线,可直接集成于PCB电路中,满足批量生产需求。

二、关键电气性能参数解析

产品核心参数直接决定适用场景,具体如下:

  1. 电感值与精度:标称电感值47μH,精度±20%(标识“470M”中,“47”为有效数字,“0”为10^0倍率,“M”代表±20%误差),满足大多数电源电路的滤波、储能误差要求,无需额外校准;
  2. 额定电流:3A(直流),指电感在工作温度范围(典型-40℃~125℃)内,持续通过且不发生磁饱和、温升不超过额定值的最大电流,可覆盖中功率DC-DC转换器(如5V/3A输出电路)需求;
  3. 直流电阻(DCR):160mΩ,反映绕组的铜损,低电阻设计可减少电流通过时的热损耗,提升电源转换效率(对比同规格绕线电感,热损耗降低约15%);
  4. 工作温度范围:-40℃~125℃(行业常规一体成型电感参数),适应高低温环境,满足车载、工业设备的宽温需求。

三、物理封装与结构特点

YSPI1050-470M采用SMD贴片封装,具体尺寸为11.5mm(长)×10mm(宽)×5mm(高),具有以下结构优势:

  • 紧凑体积:11.5×10mm的PCB footprint占用空间小,比同电感值的传统绕线电感体积缩小约20%,适合高密度电路设计(如移动设备、小型电源模块);
  • 抗振动/冲击:一体化压制结构无磁芯松动风险,可承受工业级振动(10G~20G加速度)与冲击(50G峰值),适配车载、伺服驱动器等振动环境;
  • 贴装兼容性:无引脚设计符合SMT贴装标准,可通过回流焊工艺快速集成,贴装效率比有引脚电感提升约30%,降低生产难度。

四、典型应用场景

结合参数与工艺特点,YSPI1050-470M的主要应用方向包括:

  1. 开关电源(DC-DC转换器):笔记本电脑、显示器、LED驱动电源中的降压/升压电路,负责储能与输出滤波,提升电压稳定性;
  2. 移动设备快充:智能手机、平板的快充模块(如QC/PD协议电路),需中功率电感实现高效能量传输,避免快充时过热;
  3. 工业控制电路:PLC、伺服驱动器、变频器的电源模块,依赖其抗振动特性稳定工作,减少设备故障;
  4. 车载电子:汽车中控屏、LED车灯、车载充电器的电源部分,适应-40℃~85℃的车载温度范围,满足汽车级可靠性要求;
  5. 消费电子:机顶盒、路由器、智能家居设备的电源滤波,降低电磁干扰提升信号稳定性,避免WiFi/蓝牙信号受干扰。

五、产品核心优势总结

  1. 高可靠性:一体成型工艺消除磁芯间隙,抗振动冲击,寿命长(典型MTBF≥100万小时);
  2. 低损耗高效:160mΩ低DCR减少热损耗,提升电源转换效率(典型效率≥92%);
  3. EMI抑制能力强:磁芯一体化减少漏磁,符合GB/T 17626电磁兼容标准,降低电路干扰;
  4. 紧凑适配性:小体积适配高密度PCB设计,贴装便捷,降低PCB布局难度;
  5. 宽温宽流:-40℃~125℃工作温度,3A额定电流覆盖中功率需求,无需额外并联电感;
  6. 品牌保障:益嘉源(YJYCOIN)专注电感研发生产10余年,产品经过温度循环、振动测试等可靠性验证,品质稳定。

YSPI1050-470M通过平衡电气性能、结构可靠性与体积,成为中功率电源电路的实用选择,可满足多领域对功率电感的核心需求。

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.

Replenishment inquiry Typical RFQ workflow
