Sumida CDRH5D28NP-220NC 功率电感产品概述

一、产品核心定位

CDRH5D28NP-220NC是日本胜美达(Sumida)推出的磁胶屏蔽表面贴装功率电感,针对中小功率DC-DC转换、滤波及储能场景设计。其以5.7×5.7mm紧凑贴片尺寸,平衡了电感值、电流承载能力与直流电阻(DCR),适配便携式电子、网络通信、小型家电等对体积和效率有明确要求的应用领域,是终端产品小型化与高效化的核心组件之一。

二、关键电气性能参数解析

该电感的参数设计围绕“效率提升+稳定性保障”展开,核心参数的实际意义需结合应用场景理解:

  1. 电感值与精度:标称22μH,精度±30%。此范围覆盖了大多数电源电路的滤波/储能需求(如降压电路的输出滤波、升压电路的储能),±30%的精度无需额外筛选,可直接适配批量生产中的器件一致性波动。
  2. 额定电流能力:最大连续额定电流900mA,基于“典型温升≤40K”的工作条件定义(行业常规标准)。若超过该电流,磁芯易饱和,电感值急剧下降,可能导致电路效率降低甚至器件损坏,需严格匹配电路负载电流。
  3. 低直流电阻(DCR):仅90mΩ,是提升电源效率的关键。以900mA满负载计算,功率损耗仅约0.073W,发热极小,可减少PCB散热设计压力,同时降低终端产品的待机功耗。
  4. 磁胶屏蔽特性:采用磁胶封装结构,相比非屏蔽电感可降低60%以上的电磁辐射(EMI),避免对周边敏感组件(如射频模块、传感器)的干扰,适配对电磁兼容(EMC)要求较高的设备(如通信基站终端、医疗电子辅助电路)。

三、物理特性与封装设计

  1. 贴片封装适配性:SMD封装,外形尺寸5.7×5.7mm,高度符合功率电感常规设计(无特殊高度限制),支持标准回流焊工艺,适配自动化批量生产,无需额外调整贴装设备。
  2. 磁胶结构优势:磁胶不仅起到屏蔽作用,还能增强磁芯稳定性,提升电感抗振动(可达10G以上)、抗冲击性能,适配工业环境或便携式设备的动态使用场景(如车载电子、手持仪器)。
  3. 引脚可靠性:引脚采用镀锡工艺,焊接牢固性好,长期工作中不易出现虚焊或开路故障,符合Sumida对工业级可靠性的要求。

四、品牌与可靠性优势

胜美达作为全球磁性组件领域的领军企业,CDRH5D28NP-220NC继承了品牌的核心优势:

  1. 品质一致性:采用成熟的磁芯绕制与线圈固定工艺,电感值、DCR等参数的离散性控制在±5%以内(远优于标称精度),批量应用中性能波动极小。
  2. 环保与认证:符合RoHS、REACH等全球环保标准,无铅无卤;部分型号通过UL、CE安全认证,可直接用于出口产品,降低终端认证成本。
  3. 温度适应性:支持-40℃~+85℃的宽温度范围工作,在极端环境下(如低温户外、高温工业现场)仍能保持稳定性能,不易出现电感值漂移。

五、典型应用场景

该电感因体积紧凑、低损耗、屏蔽特性,广泛适用于以下场景:

  1. 便携式电子:智能手机、智能手表、无线耳机的电源管理模块(DC-DC降压电路,需小体积、低发热);
  2. 网络通信:路由器、交换机、无线AP的次级电源电路(需EMI屏蔽,避免干扰射频信号);
  3. 小型家电:机顶盒、智能音箱、扫地机器人的电源单元(满足900mA以内电流需求,适配小型化设计);
  4. 工业控制:小型PLC、传感器模块、工业物联网(IIoT)终端的辅助电源(需可靠性与抗干扰)。

综上,CDRH5D28NP-220NC是一款“小体积、高效率、高可靠”的磁胶屏蔽功率电感,精准匹配中小功率电源电路的核心需求,是终端产品升级的优选组件。

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
