Sumida CDPH4D19FNP-100MC 磁胶屏蔽功率电感产品概述

一、产品核心身份与定位

Sumida(胜美达)作为全球被动元器件领域的领先厂商,其CDPH4D19FNP-100MC是一款专为中低功率电路设计的磁胶屏蔽表面贴装功率电感。该型号属于Sumida小型化功率电感系列,聚焦消费电子、便携式设备等对空间紧凑性、效率与抗干扰性有严格要求的场景,以小封装实现稳定的储能与滤波功能,是电源管理模块(PMIC)、DC-DC转换器等核心电路的理想适配器件。

二、关键电气参数详解

该电感的核心参数直接决定了其适用范围,需重点关注以下特性:

  1. 电感值与精度:标称电感值为10μH,精度±20%,满足常规电源滤波、储能的电感量需求,无需额外复杂的匹配设计,适配多数中低功率电源拓扑;
  2. 电流特性:
    • 额定电流(温升电流):2.32A——指电感连续工作时,自身温升控制在行业标准范围内(通常≤40℃)的最大允许电流,保证长期工作可靠性,避免过热导致性能衰减;
    • 饱和电流(Isat):800mA——定义为电感值下降30%时的临界电流,实际应用中需确保工作电流远低于此值,否则电感储能能力骤降,可能引发电源纹波过大、电路效率下降等问题;
  3. 直流电阻(DCR):65mΩ(毫欧级)——低电阻设计大幅减少铜损(功率损耗=I²×DCR),尤其在大电流场景中,能有效提升电源转换效率,降低设备发热;
  4. 屏蔽特性:磁胶屏蔽结构——相比无屏蔽电感,可显著降低电磁干扰(EMI),减少对周边敏感电路(如射频模块、传感器)的影响,简化系统EMI设计流程。

三、结构与封装特性

  1. 封装尺寸:采用2020表面贴装封装(尺寸约2.0mm×2.0mm×1.9mm,符合Sumida同系列常规规格),体积小巧,适配高度集成的小型化设备(如智能手表、蓝牙耳机);
  2. 磁芯与绕线:采用磁胶软磁材料作为磁芯,兼具低损耗、高饱和磁通密度的特点;绕线工艺采用高精度铜线,保证低DCR的同时,提升电感的机械稳定性与抗振动能力;
  3. 屏蔽设计优势:磁胶屏蔽为软磁材料包裹绕线,相比金属屏蔽更轻便,且屏蔽效果均匀,可有效抑制高频EMI,符合RoHS等环保标准,适配全球市场要求。

四、典型应用场景

该电感的参数特性使其在多领域具有广泛应用:

  1. 消费电子终端:智能手机、平板电脑的PMIC滤波电路,负责电源电压的纹波抑制,保证CPU、内存等核心器件的稳定供电;
  2. 便携式智能设备:智能手表、蓝牙耳机、TWS耳机的DC-DC升压/降压转换电路,实现电池到各模块的高效供电,同时控制设备尺寸;
  3. 物联网(IoT)终端:智能传感器、低功耗摄像头的电源管理模块,满足小电流、低损耗的需求,延长设备续航;
  4. 小型工业设备:低功率PLC、微型电机驱动电路的储能电感,保证电路的动态响应速度与稳定性。

五、性能优势与应用价值

  1. 小封装与高电流的平衡:2020小封装下实现2.32A额定电流,突破了小型电感的电流限制,为设备小型化提供了关键支持;
  2. 高效低耗:65mΩ低DCR结合磁胶软磁材料,将功率损耗控制在极低水平,尤其适合对续航敏感的便携式设备;
  3. EMI兼容性强:磁胶屏蔽有效降低了电感对外的电磁辐射,减少了系统级EMI整改的成本与时间;
  4. 可靠性稳定:Sumida的成熟制造工艺保证了电感的一致性与长期可靠性,可适应-40℃~+85℃(典型工作温度范围)的宽温环境,满足工业级与消费级设备的双重需求。

总结

Sumida CDPH4D19FNP-100MC是一款专为小型化中低功率电路设计的高性价比磁胶屏蔽功率电感,其小封装、低损耗、抗干扰的特性,使其在消费电子、便携式设备等领域具有不可替代的优势,是电源设计工程师优化电路的可靠选择。

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
