CDRH127/LDNP-100MC是胜美达(Sumida)推出的磁胶屏蔽贴片功率电感,主打「小体积+高电流+低损耗」的平衡设计,适配对电磁兼容(EMI)和空间紧凑性有要求的电源电路。产品采用SMD-4P封装(12×12mm),属于胜美达常规功率电感系列中的主流型号,广泛覆盖消费电子、工业控制等领域的DC-DC转换场景。
这款电感的核心参数直接支撑其应用价值,具体如下:
额定电感值为10μH,精度±20%——该范围能满足大多数非超精密功率电路的需求(如普通降压/升压模块),无需额外校准,降低设计复杂度。
连续直流额定电流为6.7A,磁胶屏蔽结构有效抑制磁饱和:当电流接近额定值时,电感值下降幅度远小于非屏蔽电感,确保大电流输出时仍能稳定滤波/储能,避免电压纹波过大。
DCR仅19.5mΩ,属于同规格电感的低损耗水平——铜损与电流平方成正比,6.7A下铜损约0.87W(P=I²×R),发热可控,可简化散热设计(无需额外散热片)。
采用SMD-4P(12×12mm) 封装:4引脚比传统2引脚更稳定,焊接后抗振动性能提升,适合车载/工业等可靠性要求高的场景;12×12mm紧凑尺寸可直接集成于小型电源模块(如笔记本电池管理系统)。
相比传统屏蔽罐电感,CDRH127/LDNP-100MC的磁胶屏蔽技术有两大核心优势:
基于参数与设计,这款电感主要用于以下场景:
胜美达作为全球老牌电感厂商,CDRH127/LDNP-100MC具备以下可靠性优势:
CDRH127/LDNP-100MC是一款性价比突出的磁胶屏蔽功率电感,适合需要小体积、高电流、低损耗且EMI控制的电源设计,是消费电子与工业领域的常规选型之一。

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.
