YNR4030-2R2M 磁胶屏蔽功率电感产品概述

一、产品基本定位与品牌背景

YNR4030-2R2M是益嘉源电子(YJYCOIN) 推出的一款小型化SMD磁胶屏蔽功率电感,属于该品牌“4030系列”(封装尺寸4×4×3mm)的核心产品。其定位为中低功率电源管理场景的高性价比电感,兼顾小体积、低损耗、低EMI与可靠性,适配消费电子、小型工业控制等对空间和电磁兼容要求较高的电路设计。

二、核心电气性能参数

该电感的关键指标明确,可满足多数DC-DC转换需求:

  1. 电感值与精度:标称2.2μH,公差±20%,符合功率电感常规设计,适用于开关电源的滤波、储能环节;
  2. 额定电流:最大连续工作电流2.95A(磁芯未饱和时的极限值),实际应用建议预留10%-20%裕量,避免热饱和;
  3. 直流电阻(DCR):典型值30mΩ,低DCR可显著降低导通损耗(如2.95A电流下损耗约0.26W),提升电源转换效率;
  4. 屏蔽特性:采用磁胶屏蔽结构,相比非屏蔽电感,可抑制电磁辐射(EMI),同时减少外界干扰对自身性能的影响。

三、机械与封装特性

  1. 封装尺寸:SMD贴片封装,尺寸4.0×4.0×3.0mm(长×宽×高),属于小型化功率电感范畴,可节省30%以上PCB空间;
  2. 引脚设计:标准SMD引脚,兼容回流焊、波峰焊等自动化工艺,焊接可靠性高,虚焊率低;
  3. 结构强度:磁胶屏蔽结构兼具机械稳定性与电磁性能,磁芯与线圈固定牢固,可承受常规振动、冲击环境。

四、典型应用场景

YNR4030-2R2M的参数特性适配以下主流场景:

  1. 消费电子便携设备:智能手机、平板电脑、智能手表的电源管理模块(DC-DC降压/升压),利用小体积适配紧凑空间;
  2. 小型家电与通信:智能音箱、无线路由器、机顶盒的电源滤波,低EMI减少对无线信号的干扰;
  3. 工业物联网终端:小型PLC、传感器节点、智能电表的低功率电源,可靠性满足工业级基本要求;
  4. LED驱动:小功率LED照明(台灯、应急灯)的恒流驱动,低损耗提升LED效率与寿命。

五、产品核心优势

  1. 空间效率高:4×4×3mm封装实现“小体积大电流”,比同电流非屏蔽电感体积缩小30%;
  2. 能效表现优:30mΩ低DCR降低导通损耗,适配能效敏感型产品(如便携设备);
  3. 电磁兼容好:磁胶屏蔽简化EMI整改方案,节省额外屏蔽成本;
  4. 成本平衡:益嘉源作为国内成熟厂商,性价比突出,适合批量应用于中低端至中端设备。

六、选型与使用注意事项

  1. 电流裕量:连续工作电流建议不超过2.5A(额定电流85%),避免磁芯饱和;
  2. 温度适应性:-40℃至+85℃范围内性能稳定,电感值温度系数约±0.05%/℃;
  3. 焊接规范:回流焊峰值温度≤260℃,时间≤10秒,避免损坏磁芯;
  4. 存储条件:常温(25℃±5℃)、干燥(湿度≤60%)环境存储,防止受潮导致DCR上升。

该产品凭借小体积、低损耗与低EMI特性,成为中低功率电源电路的优选电感之一,可覆盖多数消费电子与小型工业场景的需求。

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
