Sumida CDRH105RNP-220NC 功率电感产品概述

一、产品定位与核心类别

CDRH105RNP-220NC是Sumida(胜美达) 推出的磁胶屏蔽贴片功率电感,属于中小功率电感范畴,专为电子设备的电源转换、滤波及储能场景设计。该产品兼顾小尺寸、低损耗与抗干扰性能,适配自动化表面贴装(SMD)生产工艺,是批量应用的高性价比选择。

二、核心电气参数解析

该电感的关键参数明确,可覆盖多数功率电路的基础需求:

  1. 电感值与精度:标称22μH,精度±30%——宽精度设计平衡了成本与性能,适合对电感值波动容忍度较高的电源电路(如DC-DC降压/升压模块),无需过度追求高精度带来的成本提升;
  2. 电流承载能力:额定电流(Irms)3.3A(连续工作电流,电感值无明显下降),饱和电流(Isat)2.95A(电感值下降30%时的峰值电流)——实际设计需注意降额使用(通常取额定电流的80%以下),避免电流过高导致电感饱和,影响电路稳定性;
  3. 直流电阻(DCR):47mΩ(典型值)——低DCR是核心优势,可显著降低直流损耗(P=I²R),例如3A连续电流下损耗仅约0.42W,减少电感发热,提升电源效率;
  4. 屏蔽类型:磁胶屏蔽——通过磁胶封装抑制电磁干扰(EMI),降低对周边敏感电路的影响,提升整机电磁兼容性(EMC)。

三、封装与物理特性

  1. 封装形式:SMD(表面贴装),尺寸10.2mm×10mm(行业1010封装)——小尺寸节省PCB空间,适配便携式设备、高密度电路板布局;
  2. 结构特点:磁胶屏蔽结构相比非屏蔽电感,EMI性能更优,且具备机械稳定性,减少外部应力对电感性能的影响。

四、性能优势与设计价值

  1. 低损耗高效能:47mΩ低DCR大幅降低直流损耗,发热可控,无需额外散热设计,适合对能效要求高的设备;
  2. 抗干扰能力强:磁胶屏蔽隔离磁场辐射,适配EMI要求严格的场景(如医疗设备、通信基站);
  3. 成本与性能平衡:±30%精度满足多数功率电路需求,降低批量生产成本;
  4. 电流匹配性好:额定电流与饱和电流差值(0.35A)合理,避免“过饱和”风险,提升电路可靠性。

五、典型应用场景

该电感适配以下常见场景:

  1. 消费电子:笔记本电脑、平板电脑的CPU供电模块(稳定承载3A电流,低损耗提升续航);
  2. 工业控制:小型PLC、电机驱动电路的滤波/储能(磁胶屏蔽减少对模拟量的干扰);
  3. 通信设备:路由器、交换机的电源转换电路(稳定电流与低EMI适配高密度布局);
  4. 车载电子(需车规认证):车载信息娱乐系统电源模块(需确认具体型号的车规要求)。

六、品牌与可靠性

Sumida(胜美达)是全球知名磁性元件制造商,拥有数十年研发经验,产品以高一致性、高可靠性著称。CDRH105RNP-220NC符合RoHS、REACH环保标准,可满足工业与消费领域的品质要求。

该产品通过参数与结构设计,实现了“小尺寸-低损耗-抗干扰”的平衡,是多数功率电路的实用选择。

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
