YNR6045-330M 磁胶屏蔽功率电感产品概述

一、产品核心定位与典型应用场景

1. 核心定位

YNR6045-330M是益嘉源(YJYCOIN) 推出的中小功率磁胶屏蔽贴片电感,针对DC-DC转换、LED驱动等低至中功率电路设计,兼顾「小体积、低损耗、低EMI」三大核心需求,适配高密度PCB布局与自动化生产。

2. 典型应用

  • 消费电子:智能手机快充模块、平板/机顶盒电源稳压、便携式蓝牙音箱供电;
  • 物联网终端:传感器节点、智能穿戴设备的低功耗电源;
  • 小型工业设备:微型PLC辅助电源、IoT网关的DC-DC转换电路;
  • 车载低功耗场景:车载USB充电口、行车记录仪稳压模块。

二、关键参数与性能优势解析

1. 核心电气参数(明确可落地)

参数项 数值 实际意义 电感值 33μH ±20% 范围26.4μH~39.6μH,满足DC-DC电感量需求 额定电流(Isat) 1.45A 直流下电感变化≤10%的最大电流,避免磁芯饱和 直流电阻(DCR) 137mΩ 低电阻减少热损耗,提升电源效率 封装尺寸 6×6×4.5mm(SMD) 贴片封装,适配高密度PCB布局

2. 性能优势(数据支撑,避免空泛)

  • 低损耗:1.45A电流下损耗≈0.29W(I²R=1.45²×0.137),比同规格非屏蔽电感效率高2%~3%;
  • 低EMI:磁胶屏蔽可降低对外辐射15dB以上,避免干扰周边无线模块(如WiFi、蓝牙);
  • 宽裕量:额定电流留10%20%裕量(1.16A1.3A)即可稳定工作,避免过载;
  • 精度适配:±20%电感精度符合DC-DC电路设计要求(此类电路通常无需更高精度)。

三、封装与结构设计特点

1. 贴片封装适配性

  • 6×6×4.5mm SMD封装,符合IPC标准,支持回流焊(峰值260℃/10s)、波峰焊工艺;
  • 引脚间距与焊盘尺寸兼容常规PCB,无需特殊布局,适配自动化贴装。

2. 磁胶屏蔽结构

  • 材料:采用高性能铁氧体磁芯+环保磁胶包裹,磁导率稳定;
  • 优势:
    • 减少磁芯外露辐射,EMI性能优于裸磁芯电感;
    • 磁胶与磁芯结合紧密,抗振动能力达10G20G(102000Hz),适配移动设备;
    • 磁芯饱和磁通密度高,过载时电感下降更平缓。

四、可靠性与环境适应性

1. 焊接与寿命

  • 符合J-STD-020标准,回流焊无性能下降;引脚镀锡工艺,焊接牢固(虚焊率≤0.1%);
  • 额定参数下连续工作寿命≥10万小时,1000小时老化测试电感变化≤5%。

2. 环境耐受

  • 工作温度:-40℃~125℃,满足工业级(低温启动)与消费电子(高温工作)需求;
  • 湿度:95%RH(40℃)下无性能衰减,适配潮湿环境。

五、选型注意事项与替代参考

1. 选型避坑

  • 脉冲电流需按峰值计算(若峰值≥1.45A,需降额使用);
  • 若需更高电感(如47μH),选同系列YNR6045-470M;
  • 避免焊接温度超过260℃,否则磁胶可能开裂。

2. 替代参考(同参数/封装)

  • 村田LQM2HPN330MJ00(33μH±20%,1.5A,120mΩ,6×6×4.5mm);
  • TDK NLV25T-330J-PF(33μH±5%,1.2A,150mΩ,6×6×4.5mm);
  • 注:替代需确认DCR、EMI性能是否匹配应用(如无线设备需优先选屏蔽型)。

六、品牌与品质保障

益嘉源(YJYCOIN)专注功率电感10+年,该产品通过RoHS、REACH认证,环保无铅;批量采购可提供样品测试、技术支持,适配中小批量生产需求,售后响应周期≤24小时。

该产品以「高性价比+实用性能」覆盖主流中小功率场景,是电源设计中替代进口电感的优质选择。

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
