Sumida CDRH127NP-330MC 功率电感产品概述

一、产品基本定位与品牌背景

Sumida CDRH127NP-330MC是日本胜美达(Sumida)推出的磁胶屏蔽型功率电感,针对中功率电子电路的高效、小型化需求设计,属于表面贴装(SMD)无源元件。胜美达作为全球被动元件领域的资深厂商,在电感研发与制造上拥有数十年技术积累,产品以可靠性高、性能稳定著称,广泛应用于消费电子、工业控制、通信等领域。该型号电感以12×12mm的紧凑封装,兼顾通流能力与空间效率,是中功率电路电源管理、滤波等场景的适配选择。

二、核心电气参数详细解析

该型号的电气参数直接决定应用适配性,关键指标如下:

  1. 电感值与精度:标称电感量33μH,精度±20%——覆盖中功率DC-DC转换、滤波电路的常见电感量需求,精度满足多数工业及消费电子的常规应用要求,无需额外匹配高精度电路;
  2. 额定电流:3A(连续电流)——指电感在额定工作温度下可长期稳定工作的最大连续电流,能满足中小功率设备的供电需求(如笔记本电脑内存供电、小型PLC辅助电源);
  3. 直流电阻(DCR):64.8mΩ——低DCR是核心优势之一,通流损耗P=I²R,3A电流下损耗仅约0.58W,大幅降低发热,提升电源转换效率,尤其适合对续航敏感的便携设备;
  4. 磁胶屏蔽特性:采用磁胶材料包裹磁芯,相比非屏蔽电感漏磁减少70%以上,有效降低电磁干扰(EMI),满足通信基站、汽车电子等对EMC要求较高的设备需求。

三、物理封装与工艺特性

  1. 封装尺寸:12×12mm SMD封装,属于小型化功率电感范畴,适合高密度PCB布局(如智能手机主板、路由器模块),可有效节省设备内部空间;
  2. 工艺设计:线圈采用高导电率铜线绕制,磁芯为铁氧体材料搭配磁胶屏蔽,既保证电感量稳定,又减少温度系数对电感值的影响;引脚为标准SMD设计,适配回流焊工艺,生产效率高,焊接可靠性强;
  3. 耐环境性能:基于胜美达同类产品常规参数,该电感可工作于-40℃~+125℃宽温范围,耐振动(满足10G/20-2000Hz测试),适合工业及车载等恶劣环境。

四、典型应用场景

该型号电感的性能与封装特性,适配以下主流场景:

  1. 消费电子:笔记本电脑、平板电脑、智能穿戴的DC-DC降压模块(如CPU、GPU供电),低DCR提升续航,小体积适配便携设计;
  2. 工业控制:小型PLC、伺服驱动器的辅助电源,磁胶屏蔽满足EMC要求,3A电流覆盖中小功率控制电路;
  3. 通信设备:路由器、交换机、基站的电源滤波电路,抗干扰特性减少信号串扰,稳定设备性能;
  4. 车载电子:车载显示屏、传感器(摄像头、雷达)的供电模块,宽温耐振特性适配车载环境(若为商用版本,适合非安全类车载场景)。

五、产品优势与应用价值

  1. 高效低耗:低DCR与3A额定电流的平衡,减少通流损耗,提升电源效率,降低散热成本;
  2. 小型化集成:12×12mm封装适合高密度PCB设计,助力设备轻薄化;
  3. 抗干扰强:磁胶屏蔽减少EMI,降低系统EMC测试难度,无需额外加屏蔽罩,节省成本;
  4. 可靠性高:胜美达成熟工艺保证电感稳定性,宽温耐振满足多场景需求;
  5. 成本效益:平衡性能与成本,适合量产应用,是中功率电路的高性价比选择。

该型号电感凭借稳定的电气性能、紧凑封装与抗干扰特性,成为中功率电子设备电源管理系统的可靠组件,可满足多数常规场景的设计需求。

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
