PDMTAT044125-101MLU 产品概述

一、产品简介

PDMTAT044125-101MLU(品牌:PROD/谱罗德)为环型插件电感,标称电感值100 µH,公差±20%,额定直流电流3A,直流电阻(DCR)约70 mΩ,线径0.5 mm,封装尺寸约16 × 8.5 mm。该器件采用环形磁芯与规则绕组工艺,适用于电源滤波、抑制干扰和能量储存等场合,结构稳定、插件安装便捷,适配常见的手工焊接和波峰焊工艺。

二、主要特性

  • 电感值:100 µH(±20%)
  • 额定电流:3 A(连续额定)
  • 直流电阻:≈70 mΩ(典型)
  • 线径:0.5 mm,保证机械强度和电流承载能力
  • 封装:插件(through-hole),外形约16 × 8.5 mm
  • 结构:环型磁芯,低辐射、稳定的磁性能
  • 品牌:PROD(谱罗德)

三、电气性能要点

  • DCR导致的压降与发热:在额定电流3 A时,Vdrop ≈ 0.21 V,功耗 P = I²·R ≈ 0.63 W,需关注散热与温升问题。长期连续工作建议留有热裕度或采取散热/通风措施。
  • 电感随直流偏流会降低:在实际电源中,叠加的直流成分会使有效电感值下降,设计时应考虑直流偏置影响。
  • 公差±20%会影响滤波截止频率:对精确滤波电路建议预留裕量或在必要时通过实验校正。

四、机械与封装信息

  • 插件式封装,适合通孔焊接,可靠的机械固定。
  • 外形尺寸约16 × 8.5 mm,便于在常见PCB布局中安排。
  • 引脚与绕组结构适合手工焊接和自动化插件装配,焊接时遵循常规通孔元件焊接规范,避免长时间高温焊接以保护绝缘与漆包线。

五、典型应用

  • 开关电源输入/输出滤波(如降压/升压转换器的输出端)
  • DC-DC转换器中的储能电感
  • 电源线EMI抑制与噪声滤波
  • 电池管理与便携设备电源滤波
  • 工业电源与功率模块的辅助滤波场景

六、选型与设计建议

  • 若为连续重载工况,建议按80%额定电流进行选型(即约2.4 A)以降低温升并延长寿命。
  • 计算功耗与温升时必须考虑DCR带来的损耗,并在PCB布局上为热量散发留出路径。
  • 对滤波截止频率有严格要求时,考虑电感公差对电路性能的影响,必要时选择公差更小或通过并联/串联调整。
  • 评价磁饱和和直流偏置特性时,应参考样品实测或厂方详细规格书。

七、安装与使用注意事项

  • 焊接温度建议遵循通孔元器件标准工艺,避免长时间高温(一般波峰焊 ≤260°C,浸焊时间短)。
  • 避免在高湿、高腐蚀气氛中长期暴露,以免影响引线和漆包绝缘。
  • 安装时保持器件与热源(如功率MOSFET、整流器)适当距离,必要时加散热或通风。
  • 试样认证:在最终产品中使用前,建议进行温升测试、寿命和电气性能验证。

八、包装与储存

  • 插件式卷装或托盘包装,出货前应采取防潮措施。
  • 储存应避免高温、高湿、酸碱气体环境,常温干燥保存,有助于保持性能与焊接可靠性。

九、订购信息与技术支持

  • 型号:PDMTAT044125-101MLU
  • 简要描述:色环/插件电感 100 µH ±20% 3 A 70 mΩ,封装16×8.5 mm,线径0.5 mm,品牌:PROD(谱罗德)。
  • 如需更详细的电感频率特性、温升曲线、磁饱和电流等数据,请联系供应商或索取完整规格书与样品进行实际测量验证。

以上为PDMTAT044125-101MLU的产品概述与工程使用要点,适用于快速评估与电路方案设计参考。如需针对具体应用的热仿真、布局建议或更严格的性能数据,可提供应用场景以便给出更详细的建议。

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
