YNR1050-470M 磁胶屏蔽功率电感产品概述

YNR1050-470M是益嘉源(YJYCOIN)推出的表面贴装磁胶屏蔽功率电感,专为中低功率开关电源、便携电子设备及工业电源模块设计,兼具低EMI、高可靠性与紧凑封装的特点,可满足多数电源电路的储能、滤波及EMC合规需求。

一、产品定位与核心特性

作为一款SMD功率电感,YNR1050-470M的核心定位是2A级中功率、低EMI要求的电源电路,关键特性包括:

  1. 磁胶屏蔽结构:有效抑制电感电磁辐射,降低电路间EMI干扰,符合消费电子、工业设备的EMC标准;
  2. 平衡电流性能:连续额定电流2A,饱和电流3.3A,兼顾长期稳定性与瞬态过流耐受;
  3. 紧凑贴片封装:10×10mm SMD-2封装(厚度约5mm),适配自动化生产,节省PCB空间;
  4. 低损耗设计:直流电阻(DCR)仅163mΩ,减少铜损与热损耗,提升电源效率。

二、关键电气参数详解

YNR1050-470M的参数经过场景化优化,核心参数解析如下:

2.1 电感值与精度

标称47μH,精度±20%,实际范围为37.6μH~56.4μH,覆盖开关电源储能、输出滤波的典型需求,无需额外高精度匹配,降低设计成本。

2.2 电流性能

  • 额定电流(Irms):2A
    连续工作时温度上升≤40℃的最大允许电流,确保长期稳定运行;
  • 饱和电流(Isat):3.3A
    电感值下降30%时的峰值电流,可应对启动冲击、负载突变等瞬态过流场景,避免电路性能波动。

2.3 直流电阻(DCR)

标称163mΩ,反映绕组铜损:相同电流下热损耗(I²R)更低,电源效率提升约0.65%@2A,同时降低电感自身温度,延长寿命。

三、封装与物理特性

采用SMD-2表面贴装封装,物理尺寸为10mm×10mm×5mm(长×宽×高),特点包括:

  1. 无引脚设计:适配回流焊、波峰焊工艺,焊接一致性好,减少虚焊风险;
  2. 紧凑体积:适合高密度PCB布局,满足便携设备(笔记本、平板)小型化需求;
  3. 磁芯材料:高性能铁氧体磁芯+磁胶屏蔽,温度范围通常为**-40℃~+125℃**,满足宽温环境应用。

四、典型应用场景

结合参数特性,YNR1050-470M广泛适用于:

  1. 开关电源:AC-DC适配器(手机充、笔记本电源)、DC-DC降压/升压模块(12V转5V/3.3V)的储能与滤波;
  2. 便携电子:笔记本、平板、智能穿戴的电源管理单元(PMU);
  3. LED驱动:小功率LED照明(台灯、面板灯)的恒流/恒压电路;
  4. 工业电源:小型PLC、传感器模块的低功率电源;
  5. 车载电子:12V车载系统(车载充、记录仪)的电源电路(需确认温度匹配)。

五、可靠性与设计优势

  1. EMI抑制:磁胶屏蔽将辐射干扰降低10~15dB,减少对敏感元件的干扰,降低EMC测试难度;
  2. 过流耐受:饱和电流比额定电流高50%,应对瞬态过流时性能波动小;
  3. 高转换效率:低DCR与优化磁芯使效率提升2~3%(对比同规格非屏蔽电感),适合便携设备;
  4. 长寿命:磁胶结构无开裂风险,宽温稳定工作,寿命可达5万小时以上。

六、选型与使用注意事项

  1. 电流匹配:连续电流≤2A,峰值电流≤3.3A(避免过热/饱和);
  2. 精度需求:±20%适用于多数电源,高精度场景需选±10%型号;
  3. 焊接工艺:回流焊峰值温度≤245℃(时间≤10s),避免磁芯过热;
  4. PCB布局:靠近开关管/滤波节点,下方增加铜箔辅助散热;
  5. 温度环境:高温场景需确认工作温度在-40~+125℃范围内。

综上,YNR1050-470M是一款性价比高、可靠性强的磁胶屏蔽功率电感,可满足消费电子、工业及车载等领域的中低功率电源需求。

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
