YNR6045-220M 产品概述

一、概要介绍

YNR6045-220M 是益嘉源(YJYCOIN)推出的一款磁胶屏蔽功率电感,封装为 SMD 贴片(6.0×6.0×4.5mm)。额定电感值 22µH(±20%),面向中低功率开关电源与电源滤波应用,兼顾小体积与良好磁屏蔽性能,适合空间受限的 PCB 设计。

二、主要参数

  • 电感值:22µH ±20%
  • 额定电流:1.8A(持续)
  • 饱和电流 Isat(定格下降至规定值时):2.05A
  • 直流电阻 DCR:89mΩ(典型)
  • 封装:SMD,6×6×4.5mm
  • 类型:磁胶屏蔽电感(power inductor)

三、产品特点

  • 磁胶屏蔽结构,减小泄漏磁通,有利于 EMI 控制与邻近元件抗干扰。
  • 紧凑封装,适合高密度布板和多通道电源模块。
  • DCR 较低,导通损耗可控;在额定电流下的铜耗约为 I^2·R ≈ 0.29W(1.8A 时),便于热设计评估。
  • 饱和电流裕量合理,可承受短时脉冲电流而不致显著降电感。

四、典型应用

  • 降压(Buck)/ 升压(Boost)开关稳压器电感
  • 电源滤波、负载隔离与去耦电路
  • LED 驱动、电池管理与便携设备电源模块
  • 工业控制板、通信设备的电源前端

五、封装与焊接建议

  • 支持回流焊工艺,建议按 IPC/JEDEC 标准回流温度曲线进行焊接,避免长时间高温影响电感特性。
  • 焊盘设计参考制造商提供的封装图,保证良好焊锡 fillet 与热传导。
  • 贴片后建议进行温升测试与电流耐受验证,确认在实际散热条件下的温度上升与电感稳定性。

六、注意事项与可靠性

  • 建议长期工作电流不超过 1.8A,避免接近或超过 Isat 导致电感值下降与性能退化。
  • 使用时注意 PCB 上相邻磁性元件间距与方向,以免互感影响。
  • 存储与运输避免潮湿与机械冲击,如需波峰/回流后检测电气参数与外观。
  • 对降低 EMI 有更高要求时,可配合屏蔽罩或布局优化进一步提升抗干扰能力。

如需封装尺寸图、焊盘推荐或样品测试报告,可提供进一步资料以便设计验证与量产准备。

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
