YNR4026-100M功率电感产品概述

YNR4026-100M是益嘉源(YJYCOIN)推出的一款磁胶屏蔽贴片功率电感,专为小型化、低功耗电子设备的电源管理电路设计,兼具体积紧凑、电磁干扰低、损耗小等特点,适配多种DC-DC转换及滤波场景。

一、产品基本信息

该型号电感的标识清晰对应核心属性:

  • 「YNR」为益嘉源功率电感系列代码;
  • 「4026」代表贴片封装尺寸:长×宽×高=4.0mm×4.0mm×2.6mm;
  • 「100M」中「100」表示电感值10μH,「M」对应精度等级±20%。

产品类型为磁胶屏蔽功率电感,采用SMD贴片封装,支持自动化贴装,适配高密度PCB布局需求。

二、核心电气性能参数

  1. 电感值与精度:标称10μH,精度±20%,满足绝大多数电源电路的设计公差要求,无需额外高精度补偿,降低系统成本。
  2. 额定电流:1A(持续工作电流),即电感在额定温度(典型125℃)下可稳定承载的最大电流;超过此值会导致磁芯饱和,电感值急剧下降,影响电路效率与稳定性。
  3. 直流电阻(DCR):85mΩ(典型值),通流时功率损耗为I²R,1A电流下损耗仅85mW,发热低,利于设备长期稳定运行。
  4. 屏蔽特性:磁胶屏蔽结构可抑制电磁辐射(EMI),减少对周边敏感电路的干扰,符合电磁兼容(EMC)要求。

三、结构与封装优势

  1. 小型化封装:4×4×2.6mm紧凑尺寸,适配手机、智能手表、物联网传感器等小型设备的PCB空间限制,支持高密度集成。
  2. 磁胶屏蔽设计:
    • 对比非屏蔽电感,EMI辐射降低30%-50%,适合医疗、汽车电子周边等对电磁干扰敏感的场景;
    • 磁胶材料抗振动(10G以上,符合IEC 60068标准)、抗冲击,适配工业控制、车载低功耗模块;
    • 磁芯封闭性好,减少机械损伤风险,延长产品寿命。
  3. 贴片兼容性:SMD封装支持回流焊、波峰焊等自动化工艺,焊接可靠性高,适合大规模量产。

四、典型应用场景

因体积小、电流适配性强,广泛应用于:

  1. 移动终端电源:手机、智能手表、蓝牙耳机的DC-DC降压模块(电池→芯片工作电压转换);
  2. 小型家电电源:手机充电器、机顶盒、路由器的开关电源滤波电路;
  3. 物联网设备:传感器节点、智能门锁、智能家居控制器的低功耗电源管理;
  4. 工业控制模块:小型PLC、传感器接口电路的辅助电源电路。

五、选型与使用注意事项

  1. 电流匹配:实际工作电流需≤1A,若需更大电流(如1.5A以上),应选择额定电流更高的同系列型号;
  2. 焊接工艺:回流焊峰值温度≤245℃,持续时间≤10秒(避免磁胶融化);手工焊接烙铁温度≤350℃,时间≤3秒;
  3. 存储条件:常温(20-30℃)、干燥(湿度≤60%)环境,避免阳光直射、腐蚀性气体及机械冲击;
  4. PCB布局:靠近电源芯片放置,减少线路长度以降低损耗与EMI,避免与高频信号线平行布线。

总结:YNR4026-100M以紧凑体积、低损耗、低EMI的特点,成为小型化电子设备电源管理的优选元件,适配多场景低功耗电源设计需求。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
