YNR4030-101M 功率电感产品概述

YNR4030-101M是益嘉源(YJYCOIN)针对小型化电子设备推出的磁胶屏蔽贴片功率电感,兼顾电感性能与体积优势,适配低功耗电源管理、滤波等场景需求。

一、产品基本信息

1. 型号与品牌

  • 型号含义:YNR为益嘉源电感系列标识,4030对应封装尺寸(长×宽×高=4mm×4mm×3mm),101M表示电感量100μH(10×10¹)、精度±20%(M级精度);
  • 品牌:益嘉源(YJYCOIN),专注中小功率电感研发,产品覆盖消费电子、物联网等领域。

2. 封装与类型

  • 封装形式:SMD贴片封装,支持自动化回流焊,适合高密度PCB布局;
  • 产品类型:磁胶屏蔽功率电感,可有效抑制电磁干扰(EMI)。

二、核心电气参数解析

1. 电感量与精度

电感值为100μH±20%,是功率电感的核心储能参数:

  • 100μH满足多数低压DC-DC转换器(如5V转3.3V)的滤波需求,可抑制电源纹波至合理范围;
  • ±20%精度覆盖一般工程余量,无需过度追求高精度(避免成本冗余),适配消费电子、物联网设备等场景。

2. 额定电流

额定电流为450mA,指电感在25℃环境下持续工作、电感量变化≤10%的最大电流:

  • 若电路峰值电流超过450mA,电感会出现磁饱和,电感量急剧下降,导致滤波失效、电源纹波增大;
  • 该电流值适配1W以内的小功率电源模块(如移动电源、蓝牙耳机供电),避免电流过大导致的温升问题。

3. 直流电阻(DCR)

直流电阻为1.15Ω,是线圈固有电阻,直接影响功率损耗(损耗=I²×DCR):

  • 当工作电流为450mA时,损耗约0.23W,属于小功率电感的合理范围,可保证电源转换效率;
  • 1.15Ω的DCR在4×4×3mm封装中,平衡了电感量与线圈匝数(匝数越多电感量越大,但DCR会增加)。

4. 磁胶屏蔽特性

采用磁胶屏蔽工艺,对比非屏蔽电感的优势:

  • 减少对外电磁辐射,降低对蓝牙、WiFi等射频电路的干扰;
  • 提高电感抗干扰能力,避免外界磁场对电感量的影响。

三、封装与工艺特性

1. 小型化设计

封装尺寸4mm×4mm×3mm,体积紧凑:

  • 适配智能手机、智能手环、蓝牙耳机等小型化设备的高密度PCB布局;
  • 贴片封装支持自动化生产,焊点可靠性优于插件电感。

2. 材料与工艺

  • 磁芯:采用高性能铁氧体材料,温漂小、电感量稳定;
  • 线圈:漆包铜线绕制,焊接端镀锡处理,降低接触电阻,提高焊接可靠性。

四、典型应用场景

1. 消费类电子

  • 手机充电器、移动电源的DC-DC输出滤波;
  • 蓝牙耳机、智能手表的低功耗电源管理模块。

2. 物联网设备

  • 温湿度传感器、智能门锁等低功耗节点的电源滤波;
  • 小型WiFi模块、蓝牙模块的射频辅助滤波(抑制电源纹波对射频信号的干扰)。

3. 小型工业控制

  • 微型PLC的低功率电源模块;
  • 微型步进电机驱动电路的滤波。

五、使用注意事项

1. 电流与温度限制

  • 工作电流不得超过450mA,避免磁饱和;
  • 环境温度建议-40℃~85℃,超温会导致磁芯性能下降。

2. 焊接与布局

  • 回流焊峰值温度控制在230℃~250℃,避免损伤磁芯;
  • PCB布局时,电感靠近电源输出端,减少线路长度以降低损耗和干扰。

3. 存储要求

  • 存储湿度≤60%,避免线圈氧化;
  • 避免长期暴露在高温高湿环境中。

YNR4030-101M凭借小体积、低EMI、合理的电气参数,成为小型化电子设备电源管理的优选电感之一。

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
