YNR6045-680M 功率电感产品概述
一、产品定位与核心属性
YNR6045-680M是益嘉源（YJYCOIN）推出的磁胶屏蔽贴片功率电感，针对中小功率电子电路的储能、滤波及电磁干扰（EMI）抑制需求设计。其紧凑封装适配自动化贴片生产，兼顾性能稳定性与成本控制，广泛覆盖消费电子、电源管理等主流应用场景。
二、关键电气参数解析
该电感的核心参数围绕“效率”与“可靠性”平衡设计，具体解析如下：
- 电感值与精度：标称68μH，精度±20%（实际范围54.4μH~81.6μH），满足多数中小功率开关电源的电感量适配需求；
- 额定电流：允许最大直流电流1A，在额定范围内磁芯无饱和风险，电感性能保持稳定；
- 直流电阻（DCR）：典型值289mΩ，属于同规格电感的低损耗水平，可有效降低电路功耗与发热，提升电源转换效率。
三、封装与物理特性
YNR6045-680M采用SMD贴片封装，尺寸为6×6×4.5mm（长×宽×高），具备以下优势：
- 空间紧凑：适配高密度PCB设计，尤其适合小型化消费电子（如手机、智能穿戴）的电源模块；
- 工艺兼容：支持自动化贴装与回流焊（最高耐温约260℃），降低量产工艺复杂度；
- 结构稳定：磁胶包裹绕组，减少机械振动对电感性能的影响。
四、磁胶屏蔽设计优势
相比传统非屏蔽电感，磁胶屏蔽结构带来显著的EMI控制价值：
- 抑制对外辐射：磁胶包裹绕组，大幅降低电感工作时的电磁辐射，减少对周边敏感电路（如传感器、射频模块）的干扰；
- 抗外部干扰：屏蔽层阻挡外部电磁场入侵，提升电路在复杂电磁环境（如工业控制、车载场景）下的稳定性；
- 低噪声特性：磁胶的阻尼效应降低电感振动噪声，适合音频设备、医疗仪器等对噪声敏感的领域。
五、典型应用场景
结合参数与封装特性，该电感适用于以下核心场景：
- 中小功率电源模块：如手机/平板的DC-DC降压电路（5V转3.3V/1A）、笔记本电脑辅助电源；
- LED驱动电路：小型LED灯串（≤1A电流）的恒流驱动滤波；
- 智能家居控制板：智能插座、温湿度传感器的电源储能与EMI滤波；
- 小型通信设备：蓝牙模块、WiFi模块的电源管理电路。
六、选型参考要点
电路设计中选择该电感时，需注意以下细节：
- 电流匹配：确认电路工作电流≤1A，避免磁芯饱和导致电感值下降；
- 频率适配：68μH电感适合100kHz~500kHz的开关电源频率范围，需与电路工作频率匹配；
- 封装兼容：检查PCB焊盘尺寸是否匹配6×6mm封装，避免贴装误差；
- EMC需求：若电路对电磁兼容性要求较高，磁胶屏蔽设计可替代非屏蔽电感，简化后续EMC整改。
该产品凭借稳定的电气性能、紧凑封装与屏蔽优势，成为中小功率电路中高性价比的电感选型方案。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
