YNR5040-3R3M 磁胶屏蔽功率电感产品概述

一、产品核心定位与应用场景

YNR5040-3R3M是益嘉源(YJYCOIN)针对中功率密度电源系统推出的小型化磁胶屏蔽功率电感,核心定位是平衡“小体积、低损耗、低EMI”三大需求,适配消费电子、工业控制、汽车电子等领域的紧凑式电路设计。

具体应用场景包括:

  1. 消费电子:18W-65W手机快充适配器、平板/笔记本电源模块、智能穿戴BMS(电池管理系统);
  2. 工业控制:小型PLC开关电源、伺服电机驱动辅助电源、工业传感器供电电路;
  3. 汽车电子:车载USB快充、仪表盘背光电源、TPMS(胎压监测)辅助供电;
  4. 通信设备:小型路由器/交换机电源单元、IoT终端低功耗DC-DC转换器。

二、关键参数与性能优势

该电感的参数设计围绕“功率适配性”与“效率优化”展开,核心参数及价值如下:

  1. 电感值与精度:3.3uH ±20%
    3.3uH是中功率DC-DC(如BUCK拓扑)的常用规格,适配3.3V-12V输出电压、100kHz-500kHz开关频率;±20%精度满足多数功率应用的误差要求,无需额外校准。

  2. 额定电流:3.4A
    此为温升电流(电感表面升温40℃时的最大持续电流),可支撑多数中功率负载稳定运行;短期过载可耐受1.2-1.5倍峰值电流(需散热设计)。

  3. 直流电阻(DCR):24mΩ
    低DCR是降低铜损的核心——3.4A持续电流下,铜损仅约0.27W,比同类非屏蔽电感低15%以上,可提升电源转换效率1-2%(依电路设计调整)。

  4. 磁胶屏蔽特性
    磁胶封装相比非屏蔽电感,电磁辐射(EMI)降低10-15dB,无需额外屏蔽罩,节省电路空间,适配对EMI敏感的射频/传感器电路。

三、封装与结构设计特点

YNR5040-3R3M采用SMD 5040封装(5.0mm×5.0mm×4.0mm),结构兼顾小型化与可靠性:

  1. 紧凑尺寸:5×5×4mm体积适合高密度贴装,10mm²PCB面积即可实现单电感布局,适配小型化设备空间限制;
  2. 磁胶封装:耐高温环氧树脂固化后硬度高,缓冲振动冲击的同时避免线圈氧化;
  3. 端子设计:镀锡铜端子兼容回流焊/波峰焊,焊接强度≥5N(符合IPC标准),无虚焊风险。

四、可靠性与环境适应性

该电感满足工业级与汽车级基础可靠性要求:

  1. 宽温工作:-40℃至+125℃,高低温下电感值稳定(温度系数±100ppm/℃),适配极端环境(如汽车发动机舱、北方户外设备);
  2. 抗振动冲击:承受10G(20-2000Hz)振动、100G(1ms)冲击(符合IEC 60068-2-6/27标准);
  3. 焊接兼容性:回流焊峰值温度260℃(持续10s),无变形/开裂风险。

五、选型与使用注意事项

  1. 电流匹配:负载电流≤3.4A,脉冲负载峰值电流≤1.5×额定电流;
  2. 散热设计:近额定电流时,电感周边预留1-2mm散热空间,或通过PCB铜箔加强散热;
  3. EMI布局:靠近DC-DC输出端放置,缩短输出走线,进一步降低干扰;
  4. 储存条件:未焊接电感储存在25±5℃、湿度≤60%环境,避免受潮影响焊接。

总结

YNR5040-3R3M是一款性价比突出的小型化磁胶屏蔽电感,通过低DCR、低EMI与紧凑封装的组合,可有效提升中功率电源系统的效率与可靠性,适配多领域紧凑式电路设计需求。

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
