YNR5040-2R2N 磁胶屏蔽功率电感产品概述

一、产品核心定位

YNR5040-2R2N是益嘉源(YJYCOIN)推出的小型化SMD磁胶屏蔽功率电感,采用5×5×4mm标准贴片封装,专为中小功率直流电源电路设计——兼顾低损耗、小体积与电磁兼容特性,可满足消费电子、小型电源模块等场景的储能、滤波与EMI抑制核心需求,是替代同规格进口电感的高性价比选择。

二、关键参数深度解析

1. 电感值与精度

标称电感值2.2μH,精度±30%:
功率电感因工作在大电流、低频率场景,对电感值精度要求低于信号电感(信号电感通常需±5%~±10%)。±30%的精度可有效控制成本,同时满足电源纹波抑制的基本需求(电源电路中,电感值小偏差对输出纹波影响可通过电容补偿)。

2. 额定电流

3.8A(连续工作电流):
该参数指电感在25℃环境温度下,连续工作时电感值变化不超过10%的最大电流。实际饱和电流(电感磁芯饱和时的临界电流)通常高于额定电流,可覆盖10W~20W功率段的电源电路(如12V转5V/3A的快充模块)。

3. 直流电阻(DCR)

19mΩ:
低DCR是功率电感的核心优势——电流通过时的热损耗((P=I^2R))显著降低,可提升电源转换效率(每100mΩDCR在3A电流下损耗0.9W,19mΩ仅损耗0.17W),同时减少设备发热,延长电路寿命。

4. 封装尺寸

5×5×4mm SMD:
标准贴片封装适配自动化贴装设备,焊接可靠性高;小体积节省PCB布局空间,适合高密度集成设计(如手机快充适配器、路由器电源模块)。

三、封装与工艺特性

1. 磁胶屏蔽结构

采用一体化磁胶屏蔽设计:通过磁胶包裹磁芯,有效抑制电感工作时的电磁辐射,降低对周边电路的干扰,满足EMC(电磁兼容)要求(如车载电子、医疗设备等对电磁干扰敏感的场景)。

2. 高性能磁芯材料

选用铁氧体磁芯,兼顾电感量稳定性与电流承载能力:避免大电流下的磁饱和现象,同时减少磁芯损耗(磁损+铜损),进一步提升效率。

3. 贴片工艺优势

无引脚SMD封装,抗振动性能优于传统插件电感(通过振动测试:10~2000Hz,加速度1g),适用于移动设备(如笔记本电脑)、车载设备等易受振动的场景。

四、典型应用场景

  1. 消费电子快充模块:手机、平板的18W~25W快充适配器中的DC-DC降压电路(3.8A电流覆盖输出端需求);
  2. 小型直流电源:笔记本电脑辅助电源、路由器/交换机的电源模块(低DCR+小体积适配紧凑布局);
  3. LED驱动电路:低功率LED显示屏(室内小间距屏)、小型LED照明灯具的恒流驱动电路(电感储能稳定LED电流);
  4. 车载辅助电源:车载充电器、行车记录仪的电源模块(磁胶屏蔽减少对车载电子系统的干扰)。

五、品牌与品质保障

益嘉源(YJYCOIN)作为专注电感研发生产的品牌,YNR5040-2R2N通过多项可靠性测试:

  • 温度循环:-40℃~+85℃,1000次循环无失效;
  • 老化测试:额定电流下工作1000小时,电感值变化≤5%;
  • 环保认证:满足RoHS 2.0与REACH标准,无有害物质。

产品可直接替代TDK、村田等同规格电感,降低采购成本30%以上,同时保障性能一致性。

YNR5040-2R2N以“小体积、低损耗、高EMC”为核心优势,是中小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
