Sumida CDRH127/LDNP-471MC 功率电感产品概述

一、产品核心定位与身份识别

CDRH127/LDNP-471MC是日本Sumida(胜美达) 推出的磁胶屏蔽贴片功率电感,属于该品牌CDRH127系列的实用型主力产品。型号中“471”明确对应核心电感值470μH,“12×12mm”封装尺寸及SMD-4P引脚设计,使其成为中小功率电路中兼顾紧凑性、抗干扰性与成本控制的关键元件,广泛适配消费电子、工业控制及IoT设备等场景。

二、关键电气参数深度解析

该电感的参数设计围绕“实用平衡”展开,无过度冗余指标,适配大多数常规电路需求:

1. 电感值与精度

标称电感值470μH,精度±20%——这一参数符合功率电感的实用级标准,无需高精度校准即可满足DC-DC转换、滤波等基础需求,同时降低了生产端的成本控制难度。

2. 额定电流与饱和特性

额定电流1A,结合Sumida磁胶电感的材料特性,其饱和电流(Isat)通常略高于额定值(约1.1~1.2A),可确保在1A连续工作电流下,电感值变化率控制在≤10%以内,避免因饱和导致电路效率下降或纹波增大。

3. 直流电阻(DCR)

570mΩ的DCR处于同规格电感的中等水平——在1A工作电流下,损耗为(I^2R=0.57W),既保证了基础能量转换效率,又通过合理的线径设计平衡了电感值(若追求更低DCR需增大线径或减小电感量,反之则损耗过高),适配对效率要求非极致但需稳定电感量的场景。

三、物理与封装特性

1. 封装规格

采用SMD-4P(表面贴装4引脚) 封装,平面尺寸12×12mm(隐含高度约7mm,为CDRH127系列常规参数),紧凑的体积适合小型化设备的PCB布局;4引脚设计相比2引脚更易固定,可减少贴装过程中的翻转风险,提升生产良率。

2. 磁胶屏蔽结构

对比传统非屏蔽电感,磁胶屏蔽通过树脂材料包裹磁芯抑制电磁辐射,EMI性能提升约1520dB,可有效降低对周边敏感电路(如射频模块、传感器)的干扰;同时磁胶材料温度稳定性较好,工作温度范围覆盖**-40℃+125℃**(Sumida产品常规参数),适配高低温环境下的稳定工作。

四、设计优势与典型应用场景

1. 核心设计优势

  • 抗干扰性强:磁胶屏蔽减少对外辐射及外来干扰敏感度,适配EMC要求严格的场景;
  • 小型化适配:12×12mm封装满足IoT终端、智能穿戴等设备的紧凑布局需求;
  • 成本性能平衡:±20%精度、570mΩ DCR及1A额定电流,兼顾量产成本与基础性能;
  • 自动化兼容:SMD封装适配SMT生产线,提升生产效率。

2. 典型应用场景

  • 小型开关电源:如IoT设备的DC-DC降压模块(输出1A左右)、手机充电器辅助电路;
  • EMC滤波电路:路由器、机顶盒的电源滤波,减少电磁辐射;
  • 车载辅助模块:胎压监测传感器、小型车载充电器的滤波电感;
  • 工业控制小模块:PLC辅助电源、小型电机驱动的电流滤波。

五、品牌与可靠性背书

Sumida作为全球知名被动元件厂商,拥有超过50年电感研发经验,其磁胶电感以一致性好、可靠性高著称。CDRH127系列经过严格可靠性测试(高低温循环、振动、湿度测试),符合RoHS、REACH环保标准,且在汽车电子领域(AEC-Q200)的应用经验验证了其严苛环境下的稳定性,适合对可靠性要求较高的工业及汽车周边产品。

综上,CDRH127/LDNP-471MC是一款平衡紧凑性、抗干扰性与成本的实用型功率电感,可满足多场景下的中小功率电路需求,是Sumida产品线中极具性价比的选择。

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
