Sumida CDRH6D38NP-100NC 磁胶屏蔽功率电感产品概述

Sumida(胜美达)作为全球电感制造领域的领先品牌,其CDRH6D38NP-100NC是一款专为中小功率电源电路设计的磁胶屏蔽功率电感,凭借低EMI、高效率、小型化等核心优势,广泛应用于消费电子、工业控制等场景,是平衡性能与成本的优选组件。

一、产品定位与核心特性

CDRH6D38NP-100NC定位于低干扰、高效率的储能/滤波电感,核心特性围绕三大需求展开:

  1. 磁胶屏蔽抑制EMI:采用胜美达专利磁胶屏蔽工艺,有效降低电感工作时的电磁辐射,满足电子设备的EMC(电磁兼容)标准,避免对周边电路的信号干扰;
  2. 低DCR提升转换效率:直流电阻仅38mΩ,2A额定电流下功率损耗仅0.152W,大幅减少铜损,提升电源模块的整体能效;
  3. 小型化适配紧凑设计:6.7×6.7mm SMD贴片封装,适配自动化贴装,节省PCB空间,满足手持设备等小型化产品的布局需求;
  4. 稳定电流承载能力:额定电流2A范围内,电感值变化控制在精度内,避免磁芯饱和导致的性能下降,应对电路短期峰值电流更可靠。

二、关键电气参数解析

产品参数设计针对性强,直接匹配主流电源电路需求:

  • 电感值与精度:10μH ±30%,该精度等级覆盖大多数非高精度电源场景(如DC-DC降压/升压),在保证性能的前提下降低物料成本;
  • 额定电流(I₀):2A,指电感在该直流电流下,电感值相对初始值的变化率≤30%(厂家定义的稳定范围),实际饱和电流通常高于额定值,可兼容电路峰值电流波动;
  • 直流电阻(DCR):38mΩ(典型值),通过优化线圈绕制密度与线径实现低电阻,减少热量产生,延长电源模块寿命;
  • 工作频率范围:支持100kHz~2MHz(同类产品常见范围),适配主流开关电源的工作频率,无需额外调整电路参数。

三、机械封装与工艺优势

CDRH6D38NP-100NC的封装设计兼顾贴装效率与可靠性:

  1. 封装尺寸:6.7×6.7mm(长×宽),厚度符合CDRH系列标准(通常≤4mm),适合高密度PCB布局,尤其适配手持设备的紧凑空间;
  2. 贴装兼容性:SMD贴片引脚符合IPC标准,适配回流焊、波峰焊等自动化工艺,减少人工成本,提升生产良率;
  3. 磁芯工艺:采用高磁导率磁芯结合磁胶屏蔽,既保证电感储能能力,又避免磁芯外露导致的EMI问题,同时提升机械稳定性;
  4. 环保无铅:符合RoHS 2.0及REACH标准,采用无铅焊接工艺,满足全球市场的环保要求,适配出口产品设计。

四、典型应用场景

基于参数特性,CDRH6D38NP-100NC适用于以下场景:

  1. 消费电子:智能手机、平板电脑、便携式蓝牙音箱的DC-DC降压电路(如为CPU、内存供电),小型化封装适配手持设备的紧凑空间,低EMI避免信号干扰;
  2. 工业控制:小型PLC(可编程逻辑控制器)、电机驱动模块、电源适配器的滤波电感,2A额定电流满足中小功率设备的供电需求,宽温特性适应工业环境;
  3. 通信设备:路由器、交换机的电源模块,低损耗提升设备能效,屏蔽性减少对通信信号的干扰;
  4. 车载电子:若符合AEC-Q200标准(需确认具体型号),可用于车载导航、行车记录仪的辅助电源电路(注:需结合实际型号认证情况)。

五、可靠性与环境适应性

胜美达电感经过严格可靠性测试,CDRH6D38NP-100NC具备以下优势:

  • 宽温工作范围:-40℃~+125℃(典型值),适应极端环境(如北方低温、工业高温场景);
  • 抗振动/冲击:贴片封装结构坚固,通过10~2000Hz、1.5G振动测试及1000m/s²冲击测试,适合运输或工业振动环境;
  • 焊接可靠性:引脚采用抗氧化处理,回流焊峰值温度260℃(符合JEDEC标准),避免焊接时出现虚焊、假焊问题。

六、选型参考与注意事项

  1. 选型匹配:若电路峰值电流超过2A,需选择额定电流更高的CDRH系列型号(如2.5A/3A版本);若需更高精度,可考虑±20%/±10%的替代型号;
  2. PCB设计:焊盘尺寸需参考厂家datasheet,避免焊盘过大导致焊接后翘曲,或过小导致焊接强度不足;
  3. 散热设计:虽DCR低,但大电流下仍有热量产生,需在电感周围预留散热空间,或通过PCB铜箔增加散热面积;
  4. EMI优化:若电路对EMI要求极高,可配合屏蔽罩使用,进一步降低辐射干扰。

综上,CDRH6D38NP-100NC是一款性价比突出的磁胶屏蔽功率电感,适合中小功率电源电路的小型化、高效率设计,是消费电子、工业控制等领域的可靠组件。

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.
