CDRH6D28NP-100NC是Sumida(胜美达)针对高密度电子设备电源管理场景优化的磁胶屏蔽贴片功率电感,核心围绕「小体积、低损耗、低EMI」三大需求设计,适配消费电子、便携式设备及工业/汽车辅助电子等领域。其磁胶屏蔽结构可有效抑制电磁辐射,避免对周边敏感电路的干扰,同时紧凑封装满足小型化趋势。
该电感的核心参数直接决定应用适配性,具体拆解如下:
电感值为10μH(±30%),符合功率电感的典型设计逻辑——功率电感服务于DC-DC转换等场景,电感值偏差对效率影响极小,±30%的精度可覆盖绝大多数电源模块需求,同时降低生产难度与成本。
额定电流为1.7A(25℃环境下),指电感连续工作时,自身温升不超过Sumida规定限值(通常40℃-60℃)的最大电流。该值可覆盖中低功率DC-DC电路(如1-2A输出模块),避免过流导致性能衰减或损坏。
DCR仅48mΩ,属于同尺寸、同电感值电感中的低损耗水平。低DCR可显著降低铜损(P=I²×R),例如1A负载下铜损仅0.048W,有效减少电源模块发热,提升转换效率1%-2%。
采用磁胶屏蔽结构,相比非屏蔽电感,电磁辐射降低30%-50%,避免对射频电路(蓝牙/WiFi)、传感器等敏感组件的干扰,适合EMI要求严格的场景(如智能手机、汽车电子)。
CDRH6D28NP-100NC采用6.7×6.7mm SMD贴片封装,型号中「28」隐含高度约2.8mm,尺寸紧凑适配大多数PCB贴装工艺(回流焊)。引脚设计符合工业标准,可实现稳定焊接,支持批量自动化生产,降低组装成本。
结合参数与设计特性,该电感适用于以下场景:
Sumida作为全球电感龙头,CDRH6D28NP-100NC继承核心优势:
CDRH6D28NP-100NC是一款高性价比磁胶屏蔽功率电感,以「小体积、低损耗、低EMI」为核心优势,覆盖中低功率电源管理场景。参数适配性强、封装紧凑、品牌可靠性高,是消费电子、便携式设备及工业/汽车辅助电子领域的理想选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
