YNR6045-222M 磁胶屏蔽功率电感产品概述

一、产品基本识别信息

YNR6045-222M是益嘉源(YJYCOIN)推出的磁胶屏蔽功率电感,型号命名遵循行业通用规则:

  • “YNR”为品牌/系列标识;
  • “6045”对应封装尺寸(长×宽×高=6×6×4.5mm);
  • “222”代表电感值(前两位为有效数字,第三位为零的个数,即2.2mH);
  • “M”表示电感精度为±20%。

该产品为表贴式(SMD) 结构,主要用于电子电路的滤波、储能及DC-DC转换等场景,适配自动化生产工艺。

二、核心电性能参数

参数直接决定电感的适用范围,核心指标如下:

  1. 电感值与精度:标称2.2mH,精度±20%,满足多数常规电路的滤波/储能需求,无需额外高精度匹配;
  2. 电流特性:
    • 额定电流(Irms)169mA:指电感正常工作时,因直流电阻发热导致的温升不超过允许范围(通常40℃)的最大连续电流;
    • 饱和电流(Isat)205mA:指电感值下降至初始值80%时的最大峰值电流,是电路峰值电流的上限参考;
  3. 直流电阻(DCR):10Ω,反映线圈的直流损耗,需在电路功耗预算中考虑。

三、封装与物理特性

  1. 封装形式:表贴式(SMD),适配回流焊、波峰焊等常规组装工艺,支持大规模批量生产;
  2. 尺寸规格:6×6×4.5mm(长×宽×高),属于小型化封装,可有效节省PCB空间,满足便携设备的高密度布局;
  3. 磁芯与屏蔽:采用磁胶屏蔽结构,相比非屏蔽电感,可显著降低电磁干扰(EMI),减少对周边敏感元件的影响;磁胶材料稳定性优于传统铁氧体,温漂特性更优;
  4. 工作温度:常规-40℃至+125℃(益嘉源磁胶电感通用规格),覆盖多数工业及消费电子应用环境。

四、设计特点与应用优势

  1. 低EMI性能:磁胶屏蔽抑制电磁辐射,适合对电磁兼容(EMC)要求高的场景(如通信模块、医疗电子);
  2. 小尺寸高密度:6×6mm贴装面积搭配4.5mm高度,在保证电感值的前提下,适配可穿戴、智能手机等小型化产品;
  3. 电性能稳定:磁胶材料温度系数低,电感值随温度变化的漂移量小(一般±10%以内),适合宽温环境;
  4. 工艺兼容性强:无需特殊焊接设备,降低生产门槛,适配自动化组装线。

五、典型应用场景

结合参数特性,该电感主要用于:

  1. 便携电子:智能手机、平板电脑的DC-DC降压模块储能电感;
  2. 可穿戴设备:智能手环、手表的低功耗电源管理(纽扣电池供电的升压/降压转换);
  3. 通信模块:蓝牙、WiFi、LoRa无线模块的信号滤波与电源稳压;
  4. 小型家电:智能家居传感器(温湿度、运动传感器)的电源滤波;
  5. 工业低功耗电路:工业物联网(IIoT)节点的传感器供电电路。

六、选型与使用注意事项

  1. 电流匹配:连续工作电流≤169mA,峰值电流≤205mA,避免发热严重或电感值骤降;
  2. 焊接工艺:遵循回流焊温度曲线(峰值230-250℃,时间10-30秒),防止过温损坏磁芯;
  3. PCB布局:靠近负载/滤波节点,减少走线寄生电感;磁胶屏蔽面朝向PCB内部,进一步降低对外干扰;
  4. 温漂考量:高精度滤波场景需确认温度下的电感变化,必要时做温度补偿。

YNR6045-222M凭借小尺寸、低EMI、稳定性能,成为便携电子、通信及低功耗电路的常用选型,需根据电路电流、空间及EMC要求匹配使用。

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
