Sumida CDRH127NP-680MC 屏蔽功率电感器产品概述

一、产品基本信息与品牌背景

CDRH127NP-680MC是日本胜美达(Sumida)推出的一款屏蔽式功率电感器,属于其CDRH系列的小体积高功率密度产品。胜美达作为全球电感制造领域的知名品牌,以高可靠性、低损耗的电感设计著称,产品广泛覆盖消费电子、工业控制、通信等多领域。该电感采用SMD贴片封装,尺寸为12×12mm,适配高密度PCB布局需求,同时具备屏蔽结构,可有效抑制电磁干扰(EMI),满足电子设备的电磁兼容要求。

二、核心电气性能参数解析

该电感的电气参数针对电源电路的储能与滤波需求优化,关键参数清晰且适配主流电源设计:

  1. 电感值与精度:额定电感值为68μH,精度±20%,满足大多数电源回路的电感量要求(如DC-DC转换的输出滤波、储能环节),无需额外高精度匹配即可实现稳定性能;
  2. 电流特性:
    • 额定电流(Irms):2.5A,指连续工作时电感温升不超过规格书限制的最大安全电流,是实际应用中需重点遵循的电流阈值;
    • 饱和电流(Isat):2.8A,指电感值下降30%时的电流极限,设计时需确保负载电流波动不长期接近该值,避免电感性能衰减;
  3. 直流电阻(DCR):最大100mΩ,低DCR设计可降低电流通过时的功耗(I²R损耗),2.5A额定电流下功耗仅0.625W,有助于提升电源转换效率。

三、结构设计与封装优势

  1. 屏蔽式结构:采用胜美达专利的屏蔽磁芯设计,减少电感工作时的电磁辐射,降低对周边敏感电路(如射频模块、传感器)的干扰,符合EMC电磁兼容标准要求;
  2. 小体积SMD封装:12×12mm的贴片封装(厚度≤10mm,参考胜美达常规规格),适配笔记本电脑、平板等小型化电子设备的高密度PCB布局,无需占用过多空间;
  3. 绕线与磁芯材料:采用高磁导率铁氧体磁芯与优质铜线绕制,确保电感值稳定,同时降低高频损耗,适合开关电源的高频工作环境(典型频率100kHz~1MHz)。

四、典型应用场景

该电感因体积小、电流性能稳定,广泛应用于以下场景:

  1. 消费电子:笔记本电脑、平板电脑、智能电视的DC-DC降压电源模块(如CPU、内存供电);
  2. 通信设备:路由器、交换机、基站小功率电源单元的滤波电感;
  3. 工业控制:小型PLC、传感器模块、伺服驱动器的辅助电源滤波;
  4. LED驱动:小功率LED照明电源的储能电感(如室内灯、台灯驱动)。

五、选型与使用注意事项

  1. 电流余量设计:实际应用需预留10%~20%的电流余量,避免负载波动导致超过额定电流,长期工作需确保电感表面温度不超过85℃(胜美达常规电感工作温度上限);
  2. 散热考虑:低DCR虽降低损耗,但仍需注意PCB散热设计(如增加铜箔面积、合理布局散热孔),避免局部过热;
  3. 回流焊要求:遵循胜美达推荐的回流焊曲线(峰值温度260℃±5℃,时间≤10秒),避免热应力导致磁芯开裂或绕线氧化;
  4. 精度匹配:±20%的精度适合大多数电源应用,若需高精度(如≤5%),需选择胜美达其他系列产品(如CDRH高精度版本)。

六、总结

CDRH127NP-680MC作为胜美达的屏蔽功率电感,以小体积、高电流密度、低EMI为核心优势,适配多种小型化电子设备的电源设计需求。其稳定的电气性能与可靠的结构设计,使其在消费电子、通信、工业等领域具有广泛应用价值,是电源工程师选型时的优质选择之一。

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
