CDRH104RNP-470NC是日本胜美达(Sumida)推出的表面贴装功率电感,聚焦中低功率直流-直流(DC-DC)转换、滤波及储能场景。其核心价值在于平衡电感值、电流承载能力与损耗控制,以紧凑封装适配小型化设备需求,同时兼顾可靠性与成本效益,广泛适用于消费电子、工业控制及通信等领域的电源系统。
作为功率电感的核心性能指标,以下参数直接决定应用场景与设计兼容性:
电感值为47μH(微亨),精度范围**±30%**。该值属于中高频DC-DC转换的常用储能区间(典型降压电路电感多在10μH~100μH之间),宽精度范围可适配不同设计的余量需求,降低选型限制,减少精度偏差导致的性能波动风险。
直流电阻为128mΩ(毫欧),属于该封装尺寸下的低损耗水平。DCR直接决定铜损(P=I²·R),低DCR可显著减少电源转换损耗,提升效率(1A~2A区间损耗降低约25%),同时减少设备发热,延长系统寿命。
CDRH104RNP-470NC遵循Sumida CDRH104系列通用规范:
结合参数特性,产品适用于以下领域:
CDRH104RNP-470NC的核心优势可概括为“小体积、高电流、低损耗、高可靠”:
该产品以实用化参数与可靠性能,成为中低功率电源设计的优选电感之一。

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.
