252012CDMCDDS-1R0MC 产品概述

一、产品简介

252012CDMCDDS-1R0MC 是胜美达(Sumida)推出的一款一体成型功率电感,标称电感值 1 μH,公差 ±20%。该器件针对功率管理和开关电源应用优化设计,具备较高的饱和电流和低直流电阻,适合对体积与效率有较高要求的移动设备、电源模块和工业控制场景。封装为 1008 紧凑型封装,利于高密度 PCB 布局与自动化贴装。

二、主要性能特点

  • 标称电感:1 μH,精度 ±20%,满足一般滤波与储能需求。
  • 饱和电流(Isat):5.4 A,能承受较大的直流偏置而不致显著降感。
  • 直流电阻(DCR):42 mΩ,低损耗有利于提高转换效率并减少发热。
  • 一体成型结构,机械强度高、抗震动性能好,可靠性优良。
  • 1008 封装,适用于表面贴装工艺,兼容常规回流焊流程。

三、典型电气参数(摘要)

  • 电感值:1 μH ±20%
  • 饱和电流:5.4 A(Isat,定义为电感降至初始值的一定比例时对应的直流电流)
  • 直流电阻:约 42 mΩ
  • 类型:一体成型功率电感(SMD)
  • 品牌:Sumida(胜美达)
    注:实际电感随频率与直流偏置变化,建议在目标工作点进行验证。

四、应用场景

  • 同步降压(buck)和升压(boost)转换器的输入/输出滤波与能量储存。
  • 电源管理单元(PMIC)及消费类电子电源模块。
  • 工业控制板、通信设备与车载电子(视系统环境要求而定)。
  • 对体积与效率有严格要求的便携式设备与电池供电系统。

五、设计与选型建议

  • 直流偏置效应:功率电感在较大 DC 电流下电感值会下降,建议预留一定裕量,通常按饱和电流以下的安全余量选型。
  • 损耗与发热:DCR 决定直流损耗,长期高电流应用需评估温升并考虑散热。
  • 纹波电流:评估纹波电流对电感损耗与热平衡的影响,必要时选择更高 Isat 或更低 DCR 型号。
  • 布局:靠近开关管和二极管/电感的走线尽量短且宽,减小寄生电阻与磁耦。环路面积尽量小以降低 EMI。
  • 焊接兼容性:适用于标准 SMT 回流工艺,焊盘设计应遵循厂商推荐的 PCB footprint 以保证可焊性与机械强度。

六、可靠性与测试建议

  • 在样机阶段进行包括温升测试、长期老化、振动与冲击试验以及湿热循环测试,确认器件在目标环境下的稳定性。
  • 测量电感值时应标注测试频率与直流偏置条件,避免规格误差。
  • 若用于车规或高可靠性场景,建议向供应商确认相关认证与等级(如 AEC-Q 系列或类似要求)。

七、总结

252012CDMCDDS-1R0MC 是一款面向中高电流开关电源与功率管理的紧凑型一体成型电感,凭借 1 μH/5.4 A 的组合以及较低的 DCR(42 mΩ),在提高系统效率与节省 PCB 面积方面具有优势。选型时请结合实际工作电流、纹波与热环境进行验证,并遵循推荐的 PCB 布局与焊接工艺,以获得最佳性能与长期可靠性。若需更详细的电气曲线或封装图纸,请向胜美达获取完整的数据手册与样品评估资料。

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
