YNR6028-470M 功率电感产品概述

一、产品基本信息

YNR6028-470M是益嘉源(YJYCOIN)推出的磁胶屏蔽式功率电感,采用SMD贴片封装,物理尺寸为6×6×2.8mm(长×宽×高),属于小体积高密度功率电感范畴,适配各类表面贴装自动化生产工艺,广泛应用于消费电子、IoT、车载低功耗等场景。

二、核心电气参数详解

该电感的核心参数直接决定其应用边界,具体解析如下:

  1. 电感值与精度:标称电感值为47μH,精度±20%。电感值是功率电感储能、滤波的核心指标,47μH属于中值电感范围,可满足多数小功率DC-DC转换、滤波电路的阻抗匹配需求;±20%的精度覆盖了消费电子、工业低功耗场景的常规公差要求,无需额外高精度筛选。
  2. 额定电流:持续工作额定电流为1.06A。此参数指电感在25℃环境下,持续导通且电感值变化不超过10%的最大电流,是判断功率承载能力的关键——1.06A可精准适配多数1A级输出的电源模块(如手机充电器、移动电源升压电路)。
  3. 直流电阻(DCR):典型值为315mΩ。DCR反映电感线圈的铜损,数值越低则电路效率越高、发热越小。315mΩ在6×6封装的功率电感中属于较低水平,可有效降低功率损耗,提升设备续航(如移动电源)或减少散热设计成本。

三、封装与物理特性

YNR6028-470M采用磁胶屏蔽式结构,相比非屏蔽电感,可显著降低电磁干扰(EMI):磁胶将电感线圈产生的磁场约束在内部,减少对外辐射,适合对EMI敏感的场景(如音频设备、无线模块周边电路)。

其SMD 6×6×2.8mm的小体积封装,具有以下实用优势:

  • 节省空间:适配高密度集成设计(如智能手表、蓝牙耳机的电源模块);
  • 轻薄化适配:2.8mm低高度满足超薄电子设备需求(如超薄移动电源);
  • 自动化兼容:贴片式引脚设计兼容回流焊、波峰焊,提高生产效率。

四、典型应用场景

结合电气参数与物理特性,该电感的核心应用场景包括:

  1. 小功率DC-DC转换:手机充电器(5V/1A输出)、移动电源升压/降压模块、笔记本辅助电源;
  2. LED驱动电路:小型LED台灯、室内照明模组的恒流驱动电源;
  3. 智能家居/IoT:温湿度传感器、智能插座、智能门锁的电源管理模块(低EMI避免干扰无线通信);
  4. 车载低功耗电子:车载USB充电器、行车记录仪电源模块(适配12V转5V转换需求)。

五、产品优势总结

  1. 低EMI抗干扰:磁胶屏蔽减少电磁辐射,提升电路稳定性,适配EMI严格场景;
  2. 高效低耗:315mΩ低DCR降低铜损,提升效率、减少发热;
  3. 小体积高密度:6×6×2.8mm封装节省PCB空间,适配轻薄化设计;
  4. 宽温稳定:可在-40℃~85℃工作温度范围内稳定运行(符合常规功率电感标准);
  5. 易生产适配:贴片式设计兼容自动化焊接,降低生产难度与成本。

六、使用注意事项

为确保性能稳定,使用时需注意:

  1. 电流限制:持续电流不超1.06A,脉冲电流参考datasheet脉冲额定值(通常为持续电流1.5~2倍);
  2. 焊接规范:回流焊温度≤260℃,单次焊接时间≤10s,避免高温损坏内部结构;
  3. 存储环境:常温干燥(-10℃~40℃,湿度≤60%),避免受潮影响参数;
  4. 焊盘匹配:焊盘尺寸需与引脚匹配(参考datasheet推荐),避免虚焊。

YNR6028-470M凭借高性价比、稳定可靠的特点,成为消费电子、IoT等领域的实用功率电感选择。

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
