YPRH0704-2R2M 功率电感产品概述

YPRH0704-2R2M是益嘉源(YJYCOIN)推出的一款磁胶屏蔽型SMD功率电感,专为中功率电源电路设计,兼具低损耗、低EMI、紧凑尺寸等核心特性,适配多种小型化电子设备的电源管理需求。

一、产品基本信息

  • 品牌:YJYCOIN(益嘉源)
  • 型号:YPRH0704-2R2M
  • 产品类型:磁胶屏蔽功率电感
  • 封装形式:表面贴装(SMD),外形尺寸为7.3×7.3×4.5mm(长×宽×高)
  • 应用定位:中功率DC-DC转换、电源管理模块等场景

二、核心电气参数及实际意义

该电感的关键参数直接决定其应用适配性,具体解读如下:

  1. 电感值与精度:2.2μH ±20%
    电感值满足多数中功率降压/升压电路的滤波、储能需求,±20%的精度符合工业级与消费级产品的常规设计要求,无需额外高精度补偿,降低电路设计复杂度。
  2. 额定电流:6A
    额定电流下,电感的电感值变化率≤30%(行业常规规范),可稳定支撑6A以内的连续工作电流,覆盖笔记本电脑、小型服务器电源等场景的功率需求,避免因电流过载导致电感饱和失效。
  3. 直流电阻(DCR):28mΩ
    低DCR是该产品的核心优势:铜损(I²×R)随电流增大而显著降低,减少发热同时提升电源转换效率(每降低10mΩ DCR,可使6A电流下的损耗减少0.36W),尤其适合对能效要求较高的设备。

三、磁胶屏蔽结构与封装特性

  1. 磁胶屏蔽设计
    采用磁胶包裹磁芯,相比非屏蔽电感,可显著降低电磁辐射(EMI),减少对周边敏感电路的干扰,满足消费电子、通信设备的电磁兼容(EMC)标准;无需额外增加EMI滤波组件,简化电路布局,降低BOM成本。
  2. SMD紧凑封装
    7.3×7.3×4.5mm的小尺寸设计,适配高密度PCB布局,满足笔记本、平板、智能穿戴等小型化设备的空间限制;表面贴装工艺兼容回流焊(耐温范围符合行业标准),适合自动化批量生产,提升制造效率。

四、典型应用场景

结合参数与结构特性,该电感主要适用于以下场景:

  • DC-DC转换器:笔记本电脑、平板的CPU供电降压电路;
  • 电源管理模块(PMIC):路由器、交换机的电源滤波与储能回路;
  • LED驱动电源:小功率LED照明(如台灯、面板灯)的恒流/恒压电路;
  • 车载电子:低功耗车载设备(如车载充电器、仪表盘)的电源电路;
  • 通信设备:小型基站、无线AP的电源模块滤波。

五、性能优势总结

  1. 低损耗高效率:28mΩ低DCR减少铜损,降低工作温度,提升电源转换效率;
  2. EMI抑制能力强:磁胶屏蔽结构降低电磁干扰,简化电路EMC设计;
  3. 紧凑尺寸适配小型化:7.3×7.3×4.5mm封装满足高密度PCB布局需求;
  4. 高可靠性:SMD封装兼容回流焊,耐温性能稳定,适合批量生产;
  5. 宽电流覆盖:6A额定电流支撑多数中功率电源电路的连续工作需求。

该产品凭借均衡的性能与成本优势,成为消费电子、通信、车载等领域中功率电源电路的高性价比选择。

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
