YNR6045-4R7M功率电感产品概述

一、产品基本信息

YNR6045-4R7M是益嘉源(YJYCOIN)推出的磁胶屏蔽贴片功率电感,型号命名对应清晰:“YNR”为品牌系列标识,“6045”代表封装尺寸(长×宽×高=6×6×4.5mm),“4R7”表示电感值4.7微亨(μH),“M”为精度等级(±20%)。该产品采用表面贴装(SMD)工艺,适配自动化生产,是中功率电路储能、滤波的核心元件,广泛应用于电源、车载、消费电子等领域。

二、核心性能参数详解

2.1 电感与精度

电感值为4.7μH±20%,属于典型中功率电感范围,能满足DC-DC转换器、滤波电路的储能需求;±20%的精度覆盖了多数功率电路的设计裕量,无需过度追求高精度带来的成本增加,兼顾性能与经济性。

2.2 额定电流与温升

额定电流为3.3A(通常指温升电流,即持续工作时电感温度升高20℃以内的最大电流),该参数确保产品在负载下稳定运行,无磁饱和风险;结合低直流电阻(DCR),可有效降低铜损,减少发热,避免因过热导致的性能衰减。

2.3 直流电阻(DCR)

DCR仅26mΩ,远低于同尺寸普通功率电感的平均水平(约30-40mΩ),串联电阻小意味着电路损耗低、效率高,尤其适合对能效要求严格的电源模块(如快充适配器、车载电源),可将电源转换效率提升约1.5%。

2.4 屏蔽特性

采用磁胶屏蔽结构,相比非屏蔽电感,可大幅降低电磁干扰(EMI),避免对周边敏感电路(如MCU、传感器)的干扰,符合EMC电磁兼容标准;同时磁胶柔性结构抗振动性能优于铁氧体屏蔽电感,适合车载、工业振动环境。

三、封装设计与典型应用

3.1 封装优势

封装尺寸为6×6×4.5mm,属于小体积贴片封装,可有效节省PCB空间(比同参数8×8mm封装节省约40%面积),适配空间紧凑的终端产品(如笔记本电脑、智能穿戴、车载中控);SMD工艺支持回流焊,生产效率高,适合批量制造,降低人工成本。

3.2 典型应用场景

  1. 电源模块:DC-DC降压/升压转换器(如65W快充适配器、服务器12V转5V电源)的储能电感;
  2. 车载电子:车载中控、仪表盘、ADAS辅助驾驶系统的电源滤波,满足汽车级振动与温度要求;
  3. 消费电子:笔记本、平板、智能家居设备(如智能音箱)的低功耗电源电路;
  4. 工业控制:PLC、变频器的滤波与储能,适应工业环境的宽温与高可靠性需求。

四、品牌与可靠性保障

益嘉源(YJYCOIN)是国内专注于电感研发与制造的企业,产品覆盖功率电感、贴片电感等多个系列,在汽车电子、工业控制领域积累了成熟的可靠性经验。YNR6045-4R7M通过了以下行业标准测试:

  • 温度循环测试(-40℃~+85℃,1000次循环,性能衰减≤5%);
  • 振动测试(10-2000Hz,加速度2g,无结构损坏与参数漂移);
  • 耐焊接热测试(260℃回流焊,10秒,外观与性能无异常);
    确保产品在恶劣环境下长期稳定工作,无失效风险。

五、选型对比与应用优势

相比同尺寸、同电感值的非屏蔽电感:

  • EMI更低:磁胶屏蔽可将辐射干扰降低30%以上,避免电路EMC认证不通过;
  • 抗振动更好:柔性磁胶结构,抗振动性能比铁氧体屏蔽电感提升约20%;
  • 效率更高:26mΩ低DCR,比同类产品损耗降低约15%。

相比大尺寸同参数电感:

  • 体积更小:6×6×4.5mm封装,节省30%以上PCB空间,适配小型化终端;
  • 成本更低:小体积设计降低材料成本,兼顾性能与性价比,适合中低端消费电子批量应用。

该产品以“小体积、低损耗、高可靠性”为核心优势,是中功率电路设计的优选元件,可有效平衡性能、成本与空间需求。

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
