Sumida胜美达CDRH4D28NP-6R8NC功率电感产品概述

一、产品核心定位

CDRH4D28NP-6R8NC是日本胜美达(Sumida)推出的磁胶屏蔽型表面贴装功率电感,专为中低功率密度的电源电路设计,兼顾小型化、低损耗与电磁兼容性(EMC),适配消费电子、小型工业及车载辅助电源等场景,是高密度PCB布局的理想选择。

二、关键参数与性能解析

2.1 电感基础特性

  • 电感值:6.8μH,匹配多数DC-DC转换器的储能需求(如12V转5V、5V转3.3V等通用电源拓扑);
  • 精度:±30%,符合功率电感的常规精度要求,无需额外高精度校准即可满足通用电路设计;
  • 温漂特性:采用胜美达定制磁胶材料,电感值在-40℃~+125℃宽温范围波动≤10%(同类产品典型表现),适应极端环境。

2.2 电流与损耗控制

  • 额定电流:1.12A(连续工作时电感温升≤40K的最大电流),适合低至中功率电路(如单节锂电池供电的设备);
  • 直流电阻(DCR):80.7mΩ(典型值),低铜损可将功率损耗降低至约0.1W(I=1.12A时),提升电路转换效率,减少发热风险。

2.3 封装与屏蔽优势

  • 封装尺寸:4.7mm×4.7mm×2.8mm(行业常规高度),紧凑SMD封装适配0805/0603周边器件的高密度布局;
  • 磁胶屏蔽:绕组外包裹高磁导率磁胶,电磁辐射(EMI)抑制能力比非屏蔽电感提升60%以上,无需额外屏蔽罩即可满足EMC标准,简化电路设计。

三、品牌与工艺优势

Sumida作为全球电感领域的老牌厂商,CDRH4D28NP-6R8NC继承了其成熟工艺:

  1. 一致性优异:批量生产电感值偏差严格控制在±30%内,避免因电感波动导致的电源输出不稳定;
  2. 可靠性突出:磁胶与绕组的结合工艺通过振动(10G/20-2000Hz)、温度循环(-40℃~+125℃,1000次)测试,符合工业级可靠性标准;
  3. 生产适配性:SMD封装支持回流焊工艺(峰值温度245℃±5℃,时间≤10s),适合大规模自动化生产,降低制造成本。

四、典型应用场景

CDRH4D28NP-6R8NC的性能与尺寸适配以下主流场景:

  1. 便携式电子:智能手机、平板电脑的CPU/内存供电模块;
  2. 穿戴设备:智能手环、蓝牙耳机的充电电路与电源管理单元(PMU);
  3. 小型工业:PLC模块、传感器节点的辅助DC-DC电源;
  4. 车载低功率:车载USB充电口、氛围灯控制电路(非车规版本,需确认车规认证后用于车载)。

五、设计注意事项

  1. 电流降额:实际应用中建议工作电流不超过额定电流的80%(≤0.9A),避免长期高温加速磁胶老化;
  2. PCB布局:电感应靠近开关管与输出电容,减少电流回路面积(≤10mm²),降低噪声耦合;
  3. 焊接防护:回流焊时避免超过峰值温度,防止磁胶开裂;手工焊接建议使用低温焊锡(≤220℃),时间≤3s。

该产品凭借胜美达的工艺优势与平衡的性能参数,成为中低功率电源电路的高性价比选择,可有效简化设计并提升电路可靠性。

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
