YPRH1207-8R2M 功率电感产品概述

一、产品基本属性

YPRH1207-8R2M是益嘉源(YJYCOIN)推出的一款磁胶屏蔽功率电感,属于表面贴装(SMD)器件,核心参数明确且适配中功率场景:

  • 电感标称值:8.2μH,精度±20%(实际值范围6.56μH~9.84μH);
  • 额定电流:5.6A(长期工作允许的最大电流,无明显磁饱和);
  • 直流电阻(DCR):20mΩ(低阻设计,减少热损耗);
  • 封装尺寸:12×12×8mm(贴片式,适配自动化贴装);
  • 类型:磁胶屏蔽结构,电磁干扰(EMI)抑制能力强。

二、关键性能参数解析

1. 电感值与精度

8.2μH的电感值属于中等功率电感范畴,可满足DC-DC转换器、LED驱动等电路的储能需求;±20%的精度在工业级、消费电子领域已足够(若对精度要求更高,需选择±10%或±5%的型号)。

2. 额定电流

5.6A额定电流是电感在允许温升(通常≤40K) 下的长期稳定工作电流。若电路峰值电流接近或超过该值,电感可能出现磁饱和,导致电感值骤降、损耗剧增,因此实际应用需预留10%~20%裕量(建议实际工作电流≤5A)。

3. 直流电阻(DCR)

20mΩ的低DCR是核心优势:直流电阻越小,通流时的热损耗(P=I²R)越低。以额定电流5.6A计算,其损耗约为0.63W,属于低损耗水平,可有效提升电源转换效率,减少设备发热。

4. 磁胶屏蔽设计

相比非屏蔽电感,磁胶屏蔽可显著降低对外辐射干扰,同时减少外界电磁干扰对电感自身的影响,适合对电磁兼容性(EMC)要求严格的场景(如车载电子、医疗设备)。

三、适用应用场景

该电感因参数均衡、性能稳定,广泛覆盖以下场景:

  1. DC-DC转换器:笔记本电脑、显示器、路由器等设备的降压/升压电源模块(中等功率需求);
  2. LED驱动电路:LED照明、显示屏的恒流驱动(需稳定储能与低损耗);
  3. 车载电子:车载充电器、中控系统、行车记录仪的电源单元(屏蔽设计适配车载EMC环境);
  4. 消费电子:智能手机、平板的快充模块(小型化封装适配紧凑布局);
  5. 工业控制电源:小型PLC、传感器模块的辅助电源(可靠性要求高)。

四、产品优势总结

  1. 电磁兼容性能优异:磁胶屏蔽结构从根源抑制EMI,无需额外添加屏蔽罩,简化电路设计;
  2. 低损耗高效能:20mΩ低DCR大幅降低通流损耗,提升电源效率,减少设备发热;
  3. 小型化易集成:12×12×8mm贴片封装,适配自动化贴装,适合高密度PCB布局;
  4. 电流承载均衡:5.6A额定电流覆盖中等功率范围,避免过度选型导致成本浪费;
  5. 可靠性稳定:益嘉源成熟的磁胶屏蔽工艺,确保长期工作下电感值无明显衰减,适应常规工业温度范围(-40℃~+85℃)。

五、选型与使用注意事项

  1. 电流裕量预留:实际工作电流需控制在额定电流的80%以内(≤4.5A),避免磁饱和;
  2. 封装匹配:确认PCB板焊盘尺寸与12×12mm封装匹配,贴装时避免偏移;
  3. 环境温度考量:若工作环境温度超过40℃,需进一步降额(每升高10℃,额定电流降约10%);
  4. 精度适配:若电路对电感精度要求高于±20%,需更换对应高精度型号。

该产品以均衡的性能、紧凑的尺寸,成为中功率电子设备电源设计的实用选型。

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
