YNR8040-6R8M 磁胶屏蔽功率电感产品概述

一、产品核心定位与类别归属

YNR8040-6R8M是益嘉源(YJYCOIN) 推出的一款表面贴装(SMD)磁胶屏蔽功率电感,属于YNR系列小型化功率电感产品。型号中“YNR”为系列标识,“8040”对应封装尺寸(长8mm×宽8mm×高4.2mm),“6R8”表示标称电感值6.8μH,“M”为EIA标准精度代码(对应±20%),是针对中小功率DC-DC转换场景设计的通用型电感,兼顾体积紧凑性与电磁兼容性。

二、关键电气性能参数解析

该电感的核心电气参数直接决定其应用范围,具体解析如下:

  1. 电感值与精度:标称电感值6.8μH,精度±20%,满足大多数中小功率电源电路对电感值的常规要求,无需额外高精度匹配,适配批量生产的一致性需求;
  2. 额定电流:3.6A(通常为温升电流,即25℃环境下,电感值变化≤30%时的最大连续工作电流),可稳定支撑12V/5V等常见电源轨的功率输出,避免电感饱和导致电路效率下降;
  3. 直流电阻(DCR):24mΩ,低DCR设计可显著降低电流通过时的功耗(I²R损耗),3.6A工作时功耗约0.31W,减少发热对周边器件的影响,提升电路长期稳定性;
  4. 磁胶屏蔽特性:采用磁胶包裹结构,有效抑制漏磁,降低对周边敏感电路(如模拟信号、射频模块)的电磁干扰(EMI),符合低辐射设计需求,无需额外屏蔽罩即可满足多数设备的EMC要求。

三、封装与物理特性

YNR8040-6R8M采用SMD表面贴装封装,具体物理参数适配现代电子设备的小型化趋势:

  • 外形尺寸:8.0mm(长)×8.0mm(宽)×4.2mm(高),体积紧凑,可嵌入笔记本电脑、平板等便携设备的高密度PCB布局;
  • 引脚设计:标准SMD焊盘,兼容自动化贴装生产线,焊接可靠性高,减少人工焊接的不良率;
  • 材料结构:磁芯为高性能铁氧体(低损耗、高饱和磁通密度),外部包裹抗干扰磁胶,兼具低损耗与屏蔽效果,长期使用无磁胶脱落风险。

四、典型应用场景

基于其电气性能与封装特性,该电感主要适用于以下场景:

  1. 中小功率DC-DC转换器:如笔记本电脑、平板、小型服务器的12V转5V/3.3V降压电路,或5V转12V升压电路,支撑3-5A电流范围的功率输出;
  2. 电源模块:工业控制、通信设备的嵌入式电源模块,满足设备对稳定供电与低EMI的双重需求;
  3. LED驱动电源:低功率LED照明(如室内面板灯、台灯)的恒流/恒压驱动电路,低DCR设计减少电源损耗;
  4. 车载电子辅助电路:12V车载系统的USB充电模块、传感器供电电路(适配-40℃~85℃的车载环境温度范围);
  5. 低EMI要求设备:医疗电子(如便携式监护仪)、智能家居设备等对电磁辐射敏感的场景,磁胶屏蔽可避免干扰医疗信号或射频通信。

五、品牌与可靠性说明

益嘉源(YJYCOIN)是国内专注于电感研发与生产的厂家,YNR系列电感经过严格可靠性测试:

  • 环境测试:温度循环(-40℃~125℃)、湿度测试(85℃/85%RH),验证极端环境下的性能稳定性;
  • 机械测试:振动(10-2000Hz)、冲击测试,满足工业设备的振动环境要求;
  • 性能一致性:批量产品电感值偏差控制在±20%以内,DCR一致性良好,适配大规模生产需求。

六、选型与使用注意事项

  1. 电流匹配:应用电路的最大连续工作电流需≤3.6A,若峰值电流超过额定值,建议降额20%以上使用,避免电感饱和;
  2. 精度适配:±20%精度适用于常规电源电路,若需高精度(如±10%),需选择益嘉源其他系列产品;
  3. 散热设计:PCB布局时需在电感周围预留≥5mm的散热空间,避免与电解电容、MOS管等热敏器件紧密相邻;
  4. 贴装工艺:回流焊温度需符合厂家规范(峰值温度240℃~260℃,时间≤30s),避免焊接温度过高损坏磁芯;
  5. 屏蔽效果优化:虽有磁胶屏蔽,但仍需与模拟信号电路保持≥5mm距离,进一步降低干扰风险。

该电感凭借紧凑体积、低损耗与电磁兼容性,成为中小功率电源设计的高性价比选择,广泛适配消费电子、工业控制与车载等领域的常规应用需求。

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.
