YNR6028-101M — 100µH 功率磁胶屏蔽电感(6×6×2.8mm)产品概述

一、产品简介

YNR6028-101M 是由 YJYCOIN(益嘉源)推出的一款小型 SMD 功率电感,典型封装尺寸 6.0 × 6.0 × 2.8 mm,属于磁胶屏蔽结构。该器件标称电感量 100 µH,公差 ±20%,额定直流电流与饱和电流均为 650 mA,直流电阻(DCR)约 500 mΩ。凭借屏蔽磁路与紧凑体积,本品适用于空间受限且需要较好 EMI 控制的功率和滤波应用。

二、主要电气与机械参数

  • 电感值:100 µH(±20%)
  • 额定电流:650 mA
  • 饱和电流(Isat, L 下降到规定值时):650 mA
  • 直流电阻(DCR):500 mΩ(典型)
  • 类型:磁胶屏蔽电感(屏蔽式功率电感)
  • 封装/SMD 尺寸:6.0 × 6.0 × 2.8 mm
  • 品牌:YJYCOIN(益嘉源)
  • 能量存储(满流):0.5·L·I^2 ≈ 21.1 µJ

三、产品特点(要点)

  • 小型化封装,适配 SMD 贴片工艺,便于自动化装配。
  • 屏蔽结构有效抑制外部磁场泄漏,降低对周边敏感元件的干扰。
  • 额定/饱和电流相对一致,便于在中低电流应用中直接选型。
  • 中等 DCR(约 500 mΩ),对功率损耗有一定影响,适合中低功率场景。
  • 适用温度与焊接条件符合常见无铅回流工艺(具体请参考厂方完整资料与回流温度曲线)。

四、适用场景

  • 低功率 DC-DC 降压/升压转换器的输出滤波与储能。
  • 手机、可穿戴、便携设备的电源前端滤波与电流隔离。
  • EMI/EMC 抑制网络中的共模或差模滤波(取决于电路配置)。
  • 工业、智能家居、物联网终端等空间受限但对磁泄漏要求较高的场合。

五、选型建议与注意事项

  • 电流余量:尽管标称额定电流 650 mA,但为避免在工作点接近饱和时电感值下降,通常建议将持续直流偏置电流按 50%–70% 的比例降额(若对电感稳定性要求高,建议 ≤ 60%)。即持续工作电流最好控制在约 300–400 mA 范围内,确保电感不会显著降低或产生过大温升。
  • 波纹电流:在开关电源中,应考虑电感上的峰值电流(直流偏置 + 纹波幅值)。脉冲或短时过流会引起暂时性饱和,影响性能甚至导致效率下降。
  • 损耗评估:在额定电流下的铜损约为 I^2·DCR ≈ 0.65^2 × 0.5 Ω ≈ 0.21 W,长期运行会有温升,选型时需考虑 PCB 散热路径与周边元件耐温能力。

六、PCB 布局与焊接建议

  • 焊盘与过孔:推荐参考厂商推荐的焊盘尺寸与间距以保证良好焊接可靠性;两端焊盘应对称、焊盘面积适中以实现良好热散与机械固定。
  • 走线与散热:尽量将电感两端与电流路径短且粗,减少额外寄生阻抗,并为器件附近留出铜箔散热区域。
  • 防止磁耦合:若电路中存在敏感信号线或其它敏感元件,利用电感的屏蔽特性合理安排相对位置;高频开关器件应远离高阻抗节点。
  • 回流焊工艺:器件兼容无铅回流,但应按供应商建议的回流曲线控制峰值温度与时间,避免过温导致性能退化。

七、测试与可靠性建议

  • 测量电感时应在无直流偏置条件下标定基准值,并在可能的 DC 偏置情况下验证实际工作电感。
  • 评估时用合适频率范围的 LCR 仪器(典型应用频段的测量更能反映性能)。
  • 对于脉冲或高温环境应用,建议进行温升测试与长期老化评估。

八、结论

YNR6028-101M 为一款面向中低功率应用的屏蔽型 SMD 功率电感,体积小、屏蔽良好、适合对 EMI 有要求的紧凑电源设计。选用时需综合考虑实际直流与纹波电流、DCR 导致的功耗以及散热条件,合理留有电流余量以避免磁饱和引起的性能退化。若需更详细的频率特性、温升曲线或推荐焊盘尺寸,请向供应商索取完整数据手册并按其建议进行验证。

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.
