PDMTAT044125-4R7MLU — PROD(谱罗德) 4.7µH 环型插件电感产品概述

一、产品简介

PDMTAT044125-4R7MLU 是谱罗德(PROD)推出的一款高电流环型(环形)插件电感,标称电感值 4.7µH,公差 ±20%,额定直流电流 10A,直流电阻(DCR)仅 7.5mΩ。器件采用色环标识,插件封装,外形尺寸约 16 × 8.5 mm,导线线径 0.8 mm,适合大电流、低损耗的开关电源及电力电子滤波场合。

二、主要规格参数

  • 型号:PDMTAT044125-4R7MLU
  • 品牌:PROD(谱罗德)
  • 电感值:4.7 µH ±20%
  • 额定电流:10 A(连续)
  • 直流电阻(DCR):7.5 mΩ
  • 类型:环型电感(环形)/ 色环标识
  • 封装:插件(Through-hole)
  • 外形尺寸:16 × 8.5 mm(典型)
  • 线径:0.8 mm

三、主要特点与优势

  • 低损耗:7.5 mΩ 的低直流电阻在高电流条件下能显著降低 I²R 损耗与温升,提升系统效率。
  • 高电流承载:10A 额定电流满足多种中高功率电源模块需求。
  • 环型结构:磁路闭合、漏磁小,可有效抑制 EMI,适合对磁干扰敏感的应用环境。
  • 插件封装:装配与维修方便,适用于手工或波峰/选择性回流焊接的双层 PCB 方案。
  • 色环标识:便于快速识别规格,降低生产与维护出错率。

四、典型应用场景

  • 开关电源(SMPS)中的输入/输出滤波与储能元件
  • DC-DC 降压/升压转换器(Synchronous Buck/Boost)
  • 电动工具与电机驱动电源滤波
  • LED 驱动及照明电源抑制纹波
  • 电池管理系统(BMS)与便携式电源滤波
  • 工业控制与通信电源模块

五、安装与使用建议

  • 焊接:推荐使用波峰或手工焊接工艺,注意不要过度加热线圈引脚以免损伤绝缘。
  • 布局:为降低磁耦合与噪声干扰,建议电感与敏感信号线保持适当间距;若并联使用多只电感,应保证线间电流均衡及良好散热。
  • 散热:虽然 DCR 低,但在接近额定电流时仍会产生热量,应在 PCB 布局中为电感提供适当散热路径和空气流动空间。
  • 电流裕度:建议在设计中预留一定裕度(例如 20% 以上)以应对浪涌电流与长期老化导致的参数变化。
  • 测试:在样机阶段进行温升测试与电感值在工作环境下的漂移评估,确认不会出现磁饱和或明显电感下降。

六、包装与订购信息

  • 封装形式:插件(单件或卷盘/托盘包装,可根据订单要求提供)
  • 采购建议:在批量采购前建议索取样品并在目标电路中验证温升、饱和特性与 EMC 表现。若有特定包装或标识需求,请与谱罗德或授权分销商沟通确认。

七、注意事项

  • 本器件标称电感为典型值,公差 ±20%,设计时请以最坏情形(最小电感、最高损耗)进行可靠性评估。
  • 如需更高精度或特殊饱和电流/温度系数参数,请联系厂商咨询定制或替代型号。

如需元器件封装图、铁芯材料、饱和电流曲线或样品申请信息,我可以进一步为您补充并提供技术支持。

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
