Sumida CDRH6D38T125NP-470PC 功率电感产品概述

一、产品定位与核心类别

CDRH6D38T125NP-470PC是胜美达(Sumida)推出的车规级磁胶屏蔽功率电感,属于该品牌针对汽车电子及高密度功率电路设计的核心产品线。产品采用表面贴装(SMD)封装,主打“小体积+高可靠性+低损耗”特性,适配对EMI控制、宽温稳定性要求严格的场景,是车载电源、工业控制等领域的常规选型元件。

二、关键性能参数深度解析

2.1 电感与精度特性

产品标称电感值为47μH,精度±25%,满足大多数功率电路的储能需求(如DC-DC转换器的电感选型通常允许±20%~±30%误差)。采用磁胶屏蔽结构是核心设计亮点:相比非屏蔽电感,磁胶可有效抑制电磁辐射(EMI),减少对周边敏感电路的干扰,适配汽车电子等EMC要求严格的场景。

2.2 电流承载能力

  • 额定电流(Irms):1.2A:指电感在25℃环境下,温升不超过40℃(常规功率电感标准)的最大连续工作电流,是日常选型的主要参考指标;
  • 饱和电流(Isat):1A:指电感值下降30%时的电流(磁芯饱和的临界值),实际应用中需避免长期工作电流接近或超过Isat(否则电感储能能力骤降,易导致电路故障),建议实际工作电流控制在1A以内以保障可靠性。

2.3 直流电阻(DCR)与损耗

产品DCR为181mΩ,属于同规格电感中的低损耗水平:低DCR可减少电流通过时的热损耗(P=I²·R),降低电路发热,提升电源转换效率,尤其适合车载DC-DC等对效率敏感的场景。

三、封装与物理特性

产品采用SMD表面贴装封装,尺寸为6.7×6.7mm(长宽),适配常规PCB贴装工艺(如回流焊、波峰焊)。小体积设计可有效节省PCB空间,适合车载信息娱乐系统、ADAS传感器等高密度布局的模块;无引脚结构支持自动化生产,提升终端厂商的生产效率。

四、典型应用场景

因通过AEC-Q200车规认证,CDRH6D38T125NP-470PC的核心应用集中在汽车电子领域,具体包括:

  1. 车载DC-DC转换器:12V系统转5V/3.3V的降压电路(如车载充电器、显示屏供电);
  2. ADAS传感器模块:毫米波雷达、摄像头的供电电路(需宽温、抗振动);
  3. 车身控制单元(BCM):车窗、灯光等控制电路的功率储能元件;
  4. 延伸场景:工业小型开关电源、消费电子快充模块(需低EMI)。

五、可靠性与合规性

5.1 车规级认证(AEC-Q200)

通过AEC-Q200认证意味着产品满足汽车电子的严苛可靠性要求:

  • 宽温范围:支持-40℃~125℃(汽车典型工作温度);
  • 抗环境应力:通过振动(10~2000Hz)、冲击(1000m/s²)、湿度循环等测试;
  • 寿命保障:磁芯与线圈的工艺稳定性可确保10年以上车载使用寿命。

5.2 低EMI与电磁兼容性

磁胶屏蔽结构大幅降低了电感的辐射干扰,符合汽车行业的EMC标准(如ISO 11452),避免对车载通信、导航等敏感系统的干扰。

六、品牌与市场优势

胜美达(Sumida)是全球知名的电感制造商,在汽车电子电感领域有20+年技术积累:

  • 一致性优异:批量生产中电感值、DCR的偏差控制在规格范围内,减少终端电路调试成本;
  • 供货稳定:具备成熟的汽车级产能,可满足主机厂的大规模订单需求;
  • 技术支持完善:提供电感选型、电路匹配等专业服务,降低客户设计风险。

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
