Sumida CDRH104RNP-470NC 功率电感产品概述

一、产品定位与核心价值

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。

二、关键参数详解

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:

1. 电感值与精度

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。

2. 电流承载能力

  • 额定电流(Irms):1.95A:指连续工作时,电感温升不超过40℃的最大电流,是电路长期稳定运行的核心参考;
  • 饱和电流(Isat):2.1A:指电感值下降30%时的最大电流,反映过载耐受能力。此处Isat略高于Irms,可保证短时间过载(如启动、负载波动)时,电感仍维持基本储能功能,避免电源输出异常。

3. 直流电阻(DCR)

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。

三、封装与物理特性

CDRH104RNP-470NC遵循Sumida CDRH104系列通用规范:

  • 封装尺寸:10mm×10mm×4mm(长×宽×高),小型化SMD封装,适配自动化贴装,节省PCB空间;
  • 材质合规:无铅无卤合金线绕制,符合RoHS、REACH环保标准;
  • 焊接可靠:标准SMD引脚,兼容常规回流焊工艺,降低生产难度。

四、典型应用场景

结合参数特性,产品适用于以下领域:

1. 消费电子电源

  • 智能手机、平板的USB-PD快充降压模块;
  • 智能音箱、机顶盒的12V转5V/3.3V电源转换电路;
  • 便携式设备的电池管理系统(BMS)滤波单元。

2. 工业控制电源

  • 小型PLC的辅助电源模块;
  • 工业传感器节点的电源滤波电路;
  • 工业物联网(IIoT)终端的DC-DC转换电路。

3. 通信设备

  • 小型基站(Small Cell)的电源滤波单元;
  • 路由器、交换机的稳压电路;
  • 无线接入点(AP)的电池供电模块。

五、性能优势总结

CDRH104RNP-470NC的核心优势可概括为“小体积、高电流、低损耗、高可靠”:

  1. 空间利用率高:10×10×4mm封装实现2.1A饱和电流,电流密度优于同尺寸竞品;
  2. 效率提升显著:128mΩ低DCR使1A~2A区间电源效率达90%以上;
  3. 设计兼容性强:±30%精度满足多场景余量需求,宽电流范围适配负载波动;
  4. 宽温稳定:-40℃~+85℃工作范围,适合长期运行场景。

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。

Sourcing availability signal

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
