YPRH1209-331M 磁胶屏蔽功率电感产品概述

一、产品核心定位与应用场景

YPRH1209-331M是益嘉源(YJYCOIN)推出的12×12×10mm贴片式磁胶屏蔽功率电感,专为中等功率密度的电子设备设计,核心功能是实现电路储能、滤波及纹波抑制。其磁胶屏蔽结构可有效降低漏磁干扰,适合对电磁兼容性(EMC)要求较高的场景,典型应用包括:

  • 车载电子:中控屏电源模块、LED车灯驱动电路;
  • 工业控制:PLC模块、伺服驱动辅助电源;
  • 消费电子:LED照明驱动、小型DC-DC转换器;
  • 通讯设备:基站辅助电源、路由器电源滤波。

二、关键电气性能参数详解

1. 电感值与精度

电感标称值为330μH(标识“331M”中,“33”为有效数字,“1”代表10¹倍,“M”对应±20%精度),满足一般工业级设备对电感误差的要求。该电感值适配20kHz~200kHz工作频率的DC-DC电路,可平衡纹波抑制与体积成本。

2. 额定电流与饱和特性

额定电流为1.28A(通常指“温升电流”,即电感本体温度上升≤40℃时的最大持续电流)。若工作电流超过此值,磁芯易进入饱和状态,电感值会显著下降(可能降至标称值50%以下),导致电路纹波增大、效率降低。设计时建议保留20%~30%电流裕量,避免饱和风险。

3. 直流电阻(DCR)

绕组直流电阻为386mΩ,是衡量电感功耗的核心参数。以1.28A额定电流计算,静态功耗约0.63W(I²R=1.28²×0.386),在同类1210封装电感中处于较低水平,有助于提升电源转换效率,减少设备散热需求。

三、机械与封装特性

1. 紧凑贴片封装

采用SMD 12×12×10mm标准贴片封装,体积小巧,兼容自动化贴装设备(回流焊、波峰焊),适合高密度PCB布局。封装尺寸符合IPC标准,可直接替换同类进口电感,降低供应链成本。

2. 磁胶屏蔽结构

磁胶屏蔽替代传统金属屏蔽壳,优势显著:

  • 漏磁率低(≤5%),减少对周边敏感元件(晶振、传感器)的干扰;
  • 重量更轻(约2.5g),适配轻量化设备;
  • 耐温性好(磁胶耐温-40℃~125℃),适应恶劣环境。

3. 可靠性设计

绕组采用高强度漆包线,磁芯为高性能铁氧体材料,可承受多次回流焊(峰值260℃,时间≤30s),长期工作可靠性达10万小时以上,符合RoHS 2.0环保标准(无铅无镉)。

四、品牌与品质保障

益嘉源(YJYCOIN)是国内专注功率电感研发生产的企业,产品覆盖消费电子、工业、车载等领域。YPRH1209-331M通过ISO 9001认证,批量一致性好(电感值偏差控制在±15%以内,优于标称±20%),支持小批量样品测试与定制化需求。

五、选型与应用注意事项

  1. 电流匹配:实际工作电流需低于额定电流的80%(≤1.024A),避免温升过高;
  2. 频率适配:若工作频率超200kHz,需关注交流阻抗(X_L=2πfL),避免功耗过大;
  3. 焊接工艺:回流焊温度曲线需遵循厂商推荐(预热150℃180℃,时间60s90s),禁止手工焊接过热;
  4. EMC考量:若需通过CE/FCC认证,建议在电感周边增加滤波电容,进一步降低电磁辐射。

该产品凭借紧凑体积、低EMI、高可靠性,成为中等功率电子设备的优选电感方案。

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
