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。
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。
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。
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。
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:
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:
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。
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:

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
