PDMTAT068125-470MLU — 47µH 环型插件电感产品概述

一 产品简介

PDMTAT068125-470MLU 是谱罗德(PROD)出品的一款高电流环型插件电感,额定电感值为 47µH,公差 ±20%,其低直流电阻与大电流能力使其适合电源滤波与能量传输场合。封装为插件式(through‑hole),外形尺寸约 23×12mm,结构稳固,便于手工或波峰/回流焊接安装。

二 主要技术参数

  • 电感值:47 µH(±20%)
  • 额定电流:13.5 A
  • 直流电阻(DCR):约 12 mΩ
  • 类型:环型电感(toroidal)
  • 线径:1.2 mm
  • 封装:插件,外形尺寸约 23 × 12 mm
  • 品牌:PROD(谱罗德)
    说明:上述参数为典型规格,具体电气特性(如饱和电流、隔离耐压、自谐频率等)请以厂方技术资料为准。

三 结构与性能特点

  • 环型磁芯结构:磁通闭合,漏磁小,抗干扰能力强,适合集成密度较高的电源模块;
  • 低 DCR:12 mΩ 的低直流电阻有助于降低铜损,提升转换效率,尤其在高电流工作点表现优异;
  • 大电流承载:13.5 A 额定电流适合作为降压(buck)输出侧或输入滤波的电感件;
  • 插件封装:便于样机调试、工程验证及维修换件;线径 1.2 mm 保证机械强度和可靠焊接性。

四 典型应用场景

  • 开关电源(SMPS)输出滤波与能量储存;
  • DC‑DC 降压模块的大电流输出滤波;
  • 电池管理与电动工具驱动电路中需低损耗电感的场合;
  • 工业电源、服务器和通信设备的输入/输出滤波。

五 选型与应用建议

  • 纹波电流与温升:实际纹波电流应结合工作温度与散热条件评估,通常建议在额定电流的 70%–90% 范围内预留裕量以减少温升并避免磁芯饱和;
  • 直流偏置效应:在有直流偏置的应用中,电感值会随通过电流增大而下降,设计时应考虑直流偏置造成的感值衰减;
  • 频率特性:不同工作频率下的损耗与自谐频率(SRF)影响电感表现,建议在最终应用工作频率附近做实测或参考厂方频率特性曲线;
  • 并联与滤波网络:若需要更低 DCR 或更大电流能力,可考虑并联多只相同型号;在滤波设计中配合合适的电容选择能获得更佳的纹波抑制效果。

六 安装与可靠性注意事项

  • 焊接工艺:插件件可兼容常规波峰或手工焊接工艺,焊接温度与时长应遵循制造商或 IPC 标准以避免线圈绝缘和磁芯受损;
  • 机械应力:插件线脚在插入或弯折时应避免过大弯曲力矩,建议使用合适的引脚成形工具;
  • 存储与环境:避免潮湿、高温与强酸碱环境,长时间暴露在潮湿下可能影响绝缘和性能稳定性;
  • 可靠性验证:建议在批量应用前进行高温老化、振动和热循环等可靠性测试以确认长期稳定性。

七 采购与技术支持建议

选择 PDMTAT068125-470MLU 时,除本概述列出的典型参数外,应向供应商索取完整数据手册,包括电流-感值特性曲线、饱和电流(Isat)、自谐频率、绝缘耐压和温升曲线等。若应用对效率、体积或温升有更高要求,可咨询厂商或工程师寻求替代型号或定制化解决方案。

如需我帮您整理与该型号对应的电路例子、等效电路模型或对比同类替代件清单,可继续说明用途与关键指标,我将提供更精确的技术建议。

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
