Sumida CDRH4D22HPNP-100MC 功率电感产品概述

一、产品核心定位与身份识别

CDRH4D22HPNP-100MC是日本胜美达(Sumida)推出的小型贴片式功率电感,属于该品牌CDRH系列中针对低功耗场景优化的子型号。型号命名中,“CDRH”代表功率电感系列,“4D22”对应封装尺寸(4.7×4.7mm),“100MC”明确电感值为10μH(“100”表示10×10μH),是一款专为高密度PCB设计、兼顾效率与空间的基础功率电感产品。

二、关键电气性能参数解析

该电感的核心参数直接决定适用场景,以下为关键参数的实际意义:

1. 电感值与精度

标称电感值10μH,精度±20%(实际范围8μH~12μH)。此精度符合大多数电源管理电路的设计需求(如降压型DC-DC转换器通常允许±20%误差),无需额外高精度匹配,降低设计与成本控制难度。

2. 电流承载能力

  • 额定电流(Iₐ):1.3A:指连续工作状态下,电感温升不超过行业标准(40℃~50℃)的最大电流,是电源“连续负载电流”的核心参考;
  • 饱和电流(Iₛₐₜ):1.5A:指磁芯饱和时(电感值下降30%)的峰值电流。若电路存在脉冲峰值电流,需确保不超过1.5A,否则电感储能能力骤降,引发电源不稳定。

3. 直流电阻(DCR)

DCR为143.8mΩ(毫欧级),属于同类小体积电感的低损耗水平。DCR越低,铜损(I²R损耗)越小,电源转换效率越高,适配便携设备的低功耗需求。

三、物理封装与安装特性

采用SMD贴片封装,尺寸4.7×4.7mm(长宽),具备以下优势:

  • 高密度适配:小体积节省PCB空间,适合便携电子、物联网终端等迷你化产品;
  • 自动化贴装:兼容主流SMT生产线,实现高速批量生产,降低人工成本;
  • 散热优化:封装底部与PCB直接接触,通过铜箔辅助散热,缓解小体积热集中问题。

四、品牌可靠性与适用场景

胜美达作为全球被动元件龙头,在功率电感领域有数十年技术积累,产品覆盖汽车、消费电子、工业等领域。CDRH4D22HPNP-100MC依托品牌可靠性,主要适用:

1. 消费电子电源

如智能手机、平板的降压DC-DC转换器(电池转CPU/内存低电压),满足低功耗、小体积需求;

2. IoT终端

如智能手环、智能家居传感器的辅助电源,低DCR与小体积适配“低功耗+迷你化”设计;

3. 小型工业设备

如小型PLC、传感器模块的电源单元,1.3A额定电流覆盖多数小型负载连续工作;

4. 便携式医疗设备

如血糖仪、血压计的电源电路,可靠性符合医疗设备基本要求。

五、选型与使用注意事项

  1. 电流裕量:连续电流≤1.3A,峰值≤1.5A,建议预留10%~20%裕量;
  2. 精度匹配:若需高于±20%精度(如高精度模拟电路),需换其他子型号;
  3. 散热设计:大电流工作时,PCB需预留足够铜箔面积,或增加散热片;
  4. 焊接工艺:采用回流焊,避免手工焊接导致虚焊或热损伤。

综上,CDRH4D22HPNP-100MC是一款性价比高、适配性强的小体积功率电感,兼顾效率、尺寸与可靠性,适合多数低功耗、高密度电源管理场景。

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
