Sumida CDRH127/LDNP-100MC 功率电感产品概述

一、产品核心定位与基础属性

CDRH127/LDNP-100MC是胜美达(Sumida)推出的磁胶屏蔽贴片功率电感,主打「小体积+高电流+低损耗」的平衡设计,适配对电磁兼容(EMI)和空间紧凑性有要求的电源电路。产品采用SMD-4P封装(12×12mm),属于胜美达常规功率电感系列中的主流型号,广泛覆盖消费电子、工业控制等领域的DC-DC转换场景。

二、关键性能参数详解

这款电感的核心参数直接支撑其应用价值,具体如下:

1. 电感值与精度

额定电感值为10μH,精度±20%——该范围能满足大多数非超精密功率电路的需求(如普通降压/升压模块),无需额外校准,降低设计复杂度。

2. 额定电流与饱和特性

连续直流额定电流为6.7A,磁胶屏蔽结构有效抑制磁饱和:当电流接近额定值时,电感值下降幅度远小于非屏蔽电感,确保大电流输出时仍能稳定滤波/储能,避免电压纹波过大。

3. 直流电阻(DCR)

DCR仅19.5mΩ,属于同规格电感的低损耗水平——铜损与电流平方成正比,6.7A下铜损约0.87W(P=I²×R),发热可控,可简化散热设计(无需额外散热片)。

4. 封装与引脚设计

采用SMD-4P(12×12mm) 封装:4引脚比传统2引脚更稳定,焊接后抗振动性能提升,适合车载/工业等可靠性要求高的场景;12×12mm紧凑尺寸可直接集成于小型电源模块(如笔记本电池管理系统)。

三、磁胶屏蔽的设计优势

相比传统屏蔽罐电感,CDRH127/LDNP-100MC的磁胶屏蔽技术有两大核心优势:

  • EMI抑制好:磁胶约束磁场泄露,减少对周边电路的干扰,适配通信基站、医疗仪器等EMI敏感设备;
  • 热传导高效:磁胶导热性优于金属屏蔽罐,可快速将热量传递至PCB,进一步降低工作温度。

四、典型应用场景

基于参数与设计,这款电感主要用于以下场景:

  1. 消费电子电源:笔记本、平板的DC-DC降压模块(为CPU/GPU供电),需大电流、小体积且低发热;
  2. 工业控制设备:PLC、伺服驱动器的电源单元,对可靠性与EMI要求高;
  3. 通信设备:路由器、交换机的电源模块,需稳定大电流支撑多端口传输;
  4. 小型储能:便携式充电宝升压模块(快充供电),需低损耗提升转换效率。

五、品牌与可靠性保障

胜美达作为全球老牌电感厂商,CDRH127/LDNP-100MC具备以下可靠性优势:

  • 符合RoHS、REACH环保标准,无铅焊接兼容;
  • 批量一致性好:电感值、DCR偏差控制在规格内,减少电路调试成本;
  • 宽温适配:工作温度范围(-40℃~+125℃,参考官方 datasheet)覆盖工业级需求。

总结

CDRH127/LDNP-100MC是一款性价比突出的磁胶屏蔽功率电感,适合需要小体积、高电流、低损耗且EMI控制的电源设计,是消费电子与工业领域的常规选型之一。

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
