Sumida CDRH5D28NP-6R2NC 功率电感产品概述

一、产品基本信息

CDRH5D28NP-6R2NC是日本胜美达(Sumida)推出的一款磁胶屏蔽贴片功率电感,专为中小功率电源电路设计。作为Sumida功率电感系列的经典通用型号,其采用贴片式封装适配自动化SMT生产,广泛应用于消费电子、工业控制等领域的DC-DC转换、滤波及储能场景。

二、核心参数详解

该型号的关键参数直接决定了其适用边界,具体解析如下:

  • 电感值与精度:标称6.2μH,精度±30%。此精度符合功率电感的设计逻辑——功率电路对电感值的绝对精度要求低于高频精密电感,±30%的范围能稳定满足电源转换中的储能需求,同时降低制造成本;
  • 额定电流:1.8A(直流电流)。指电感在25℃环境下持续工作时,电感温度升高不超过40℃(行业常规允许值)的最大电流,可覆盖中小功率设备(如手机充电器、小型PLC)的电源输出需求;
  • 直流电阻(DCR):33mΩ(典型值)。低DCR是该型号的核心优势——电阻越小,电流通过时的铜损(功率损耗=I²×R)越低,能有效降低电感发热,提升电源转换效率(尤其在1A以上电流下,损耗减少约20%比同类高DCR型号);
  • 屏蔽类型:磁胶屏蔽。通过磁胶封装结构将电感工作时的电磁辐射(EMI)抑制在内部,避免对周边敏感元件(如蓝牙模块、WiFi天线)造成干扰,符合多数电子设备的EMC标准。

三、封装与物理特性

CDRH5D28NP-6R2NC采用5.7×5.7mm贴片封装(高度约3mm,结合Sumida同系列型号推断),物理特性适配高密度设计:

  1. 体积小巧:5.7×5.7mm的 footprint 适合小型化设备(如移动电源、蓝牙耳机)的PCB布局,可节省约30%的空间比传统插件电感;
  2. 屏蔽结构稳定:磁胶屏蔽层不仅抗EMI,还能保护内部线圈,提升机械强度,降低振动导致的参数漂移风险(适合工业设备的振动环境);
  3. 宽温可靠性:Sumida该系列电感通常支持-40℃~+125℃工作温度,满足工业级、车载辅助电路等宽温场景的长期稳定运行。

四、设计优势与应用特点

相比同类非屏蔽电感或高DCR型号,该型号的核心优势体现在:

  1. 高效低耗:33mΩ低DCR大幅减少铜损,可降低电源模块整体发热,延长设备寿命(实测1.5A持续电流下,电感表面温度仅比环境高35℃);
  2. 抗干扰强:磁胶屏蔽抑制电磁辐射,避免与周边射频元件干扰,提升设备稳定性(如蓝牙耳机使用时无信号串扰);
  3. 生产兼容:贴片式封装适配标准SMT贴片机,可实现高速自动化生产,降低人工成本(适合批量订单);
  4. 性价比突出:作为胜美达的通用型号,性能稳定且成本可控,适合中低端消费电子与工业设备的批量应用。

五、典型应用场景

该型号的参数与特性决定了其主要应用于以下场景:

  1. 消费电子:手机快充充电器(5V/2A输出)、移动电源的DC-DC降压模块,蓝牙耳机、智能手表的电源管理电路;
  2. 工业控制:小型PLC(可编程逻辑控制器)、传感器模块的电源滤波电路,低压直流电机(12V/1A)驱动电路;
  3. 车载辅助电路:车载充电器(12V转5V)、行车记录仪的电源转换模块(需确认温度范围匹配);
  4. 通信设备:家用路由器、交换机的电源滤波与储能电路(24V转5V)。

六、选型注意事项

使用前需注意以下几点,避免性能异常:

  1. 电流匹配:工作电流不超过1.8A,峰值电流建议留20%余量(不超2.16A),否则会导致电感过热、参数漂移;
  2. 精度需求:±30%精度适合功率储能,若用于精密滤波(如射频电路),需换更高精度(±10%)型号;
  3. EMI要求:若设备对EMI无严格要求,可考虑非屏蔽电感降低成本;若需符合EMC标准,磁胶屏蔽是必要选择;
  4. 温度环境:确认工作温度在-40℃~+125℃范围内,超出则需更换耐高温型号(如Sumida汽车级系列)。

综上,CDRH5D28NP-6R2NC是一款性能均衡、性价比突出的中小功率磁胶屏蔽电感,适合多数电子设备的电源电路需求。

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.
