PDPTAT0810-4R7M 产品概述

一、产品简介

PDPTAT0810-4R7M 是谱罗德(PROD)推出的一款径向插件工字型电感,标称电感值 4.7 μH,公差 ±20%。该器件针对中高电流、低损耗的电源滤波和能量储存场合设计,具备 5.2 A 的额定电流能力与 6.8 A 的饱和电流(Isat),直流电阻(DCR)约为 16 mΩ。外形小巧、可靠性高,便于通过插件(穿孔)工艺装配与波峰/手工焊接。

二、主要技术参数

  • 型号:PDPTAT0810-4R7M
  • 电感值:4.7 μH
  • 公差:±20%
  • 额定电流(Ir):5.2 A(持续工作电流,亦称额定电流)
  • 饱和电流(Isat):6.8 A(电感降额或小于规定电感值时的电流)
  • 直流电阻(DCR):约 16 mΩ(典型值)
  • 类型:工字电感(色环标识 / 插件)
  • 封装与外形:径向引线,机体尺寸 D9.5 × L12 mm;推荐 PCB 安装间距 / 占位约 8 × 10 mm
  • 品牌:PROD(谱罗德)

(注:以上参数以出厂品检和典型值为准,详细的环境和温度特性请参见厂方完整数据手册。)

三、结构与外形说明

PDPTAT0810-4R7M 采用工字型磁芯结构,线圈外覆环形标识(色环)以便快速识别电感值和公差。径向引线设计适合穿孔插件(THT)装配方式,机体直径约 9.5 mm、长度约 12 mm,占位面积小,适合空间受限但需高电流承载的 PCB 布局。引线间距与落位矩形约为 8×10 mm,便于在常规通孔板上布局。

四、主要特性与优势

  • 高电流能力:额定 5.2 A、饱和 6.8 A,适合中高电流的滤波、储能场合。
  • 低直流损耗:DCR 仅约 16 mΩ,能有效降低 I²R 损耗,提高效率并减少发热。
  • 小体积:D9.5×L12 mm 的紧凑外形,兼顾空间利用率与散热需求。
  • 插件工艺兼容性:径向引线便于波峰焊、手工焊接及维修替换,适合快速样板验证与量产。
  • 易识别与替换:色环标识有利于产线分拣与现场维护。

五、典型应用场景

  • 开关电源(SMPS)输出滤波与能量储存
  • DC-DC 降压/升压转换器的功率链路电感
  • LED 驱动电源与汽车电子中的滤波/储能环节(视整机环境与认证要求)
  • 电机驱动控制器与高频电源模块的 EMI 滤波
  • 各类工业电源与消费电子大电流输出端滤波元件

六、选型与使用建议

  • 电流裕量:为避免电感进入饱和或出现过高温升,建议实际工作电流低于额定电流(Ir)并远低于 Isat;在脉冲或瞬态电流较大的场合,应考虑适当的裕量或选用更高 Isat 的型号。
  • DCR 与发热评估:直流电阻为器件发热的主要因素之一,系统热设计应考虑 DCR 对整体损耗的贡献。
  • 布局与散热:尽量将器件置于良好通风或靠近散热部位的位置,避免与高温器件紧密堆叠;保持引线和焊点的可靠连接以减少接触电阻。
  • 焊接工艺:插件件适合波峰焊与手工焊,具体的焊接温度与时间应参照厂方工艺规范,避免长时间高温破坏漆包线与绝缘材料。
  • 测试与验证:样机阶段应对电感在目标工作频率和电流下进行电感值、损耗和温升测试,验证在系统工况下不会产生过度非线性或饱和。

七、存储与可靠性注意事项

  • 存放环境避免潮湿、高温和腐蚀性气体,建议保持干燥、常温条件。
  • 长期存放前建议避光、防尘并放置在防静电或防潮包装内。
  • 安装时注意避免对引线处过度弯曲或机械应力,防止引线疲劳或断裂。

八、常见替代与兼容说明

在替换或升级时,优先匹配以下关键参数:电感值、额定电流/饱和电流、DCR、封装尺寸与引脚间距。相同或更高的 Isat 与相近电感值可提高容错性,但需兼顾体积与电气性能。建议在更换前对新元件进行温升和电磁兼容测试验证。

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
