Sumida CDRH4D28NP-2R2NC 功率电感产品概述

一、产品核心定位

CDRH4D28NP-2R2NC是Sumida(胜美达)推出的小型化表面贴装功率电感,针对空间受限、中等功率需求的电子电路设计,兼顾效率与成本控制,适用于消费电子、小型电源、IoT设备等多场景。作为胜美达CDRH4D系列的成熟产品,它延续了品牌在功率电感领域的绕线工艺与磁芯优化技术,满足量产稳定性与长期可靠性要求。

二、关键参数深度解析

该产品的核心参数直接决定了其应用场景适配性,具体解析如下:

  1. 电感值与精度:标称2.2μH,精度±30%。此精度范围适用于对电感量波动容忍度较高的场景(如电源滤波、储能回路),无需额外高精度补偿,降低设计复杂度。
  2. 额定电流:2.04A(对应环境温度25℃下,电感温度上升40K时的最大允许电流)。该电流能力可覆盖大多数小型开关电源、便携式设备辅助电源的功率需求,避免电感饱和导致的电压波动或效率下降。
  3. 直流电阻(DCR):23.2mΩ的低DCR是核心优势。低电阻可显著减少工作时的铜损(P=I²·R),提升电路转换效率,尤其适合电池供电设备(如智能手机、智能手表的电源模块),延长续航时间。
  4. 封装尺寸:4.7×4.7mm的SMD封装,平面尺寸紧凑,适配高密度PCB布局,满足便携式设备的小型化需求。

三、封装与物理特性

该产品采用无铅表面贴装封装,具备以下特点:

  • 自动化适配:封装设计符合IPC标准,支持回流焊、波峰焊等常规工艺,可直接用于自动化生产线,提升量产效率。
  • 结构稳定性:磁芯与线圈一体化绕制,减少机械振动导致的电感量波动,长期运行可靠性高。
  • 空间效率:4.7×4.7mm的平面尺寸仅占用少量PCB面积,适合多电感并联或高密度电路设计。

四、典型应用场景

结合参数特性,该产品主要应用于以下领域:

  1. 消费电子:智能手机、平板电脑、智能手表的电源管理模块(如DC-DC降压转换器的储能电感),低DCR与小尺寸完美适配设备的功耗与空间限制。
  2. 小型开关电源:5V/1A、12V/0.5A等低功率适配器、LED驱动电源(如小功率LED灯带、台灯驱动),2.2μH电感值可满足滤波与储能需求。
  3. IoT与传感器节点:智能家电、工业传感器节点的辅助电源电路,低功耗设计延长电池续航,小尺寸便于设备小型化部署。
  4. 车载辅助电路:车载信息娱乐系统的低功率模块(如USB充电接口、小屏幕背光驱动),符合汽车电子的基本可靠性要求(若需车规级需确认具体型号)。

五、品牌与可靠性优势

Sumida(胜美达)作为全球电感领域的领先厂商,拥有60余年无源元件设计经验,CDRH4D系列产品具备:

  • 工艺一致性:采用高精度绕线与磁芯烧结技术,批量产品的电感值、DCR波动极小,减少电路调试复杂度。
  • 环保合规:符合RoHS、REACH等欧盟环保标准,无铅封装满足绿色制造要求。
  • 可靠性验证:通过温度循环(-40℃~+85℃)、湿度测试(85℃/85%RH)等常规可靠性测试,可长期稳定运行于工业级环境。

六、选型与使用注意事项

为确保产品性能稳定,需注意以下要点:

  1. 电流匹配:若应用场景峰值电流超过2.04A,需选择同系列更高电流规格(如CDRH4D28NP-3R3NC等),避免电感饱和。
  2. 精度需求:若对电感量精度要求高于±30%(如射频滤波、高精度电源),需更换为胜美达高精度系列(如CDRH3D16系列)。
  3. 焊接工艺:遵循胜美达推荐的回流焊曲线(峰值温度240~260℃,时间≤10秒),避免过热损坏封装。
  4. 储存条件:未开封产品储存在-40℃~+85℃、湿度≤60%环境中,开封后12个月内使用完毕,防止受潮影响焊接可靠性。

综上,CDRH4D28NP-2R2NC凭借小尺寸、低损耗、中等电流能力与高可靠性,成为小型化电子电路的优选功率电感,适用于多领域的量产应用。

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.
