PDPTAT0608-3R3M 产品概述

一、产品简介

PDPTAT0608-3R3M 是谱罗德(PROD)系列的一款插件式工字电感,标称电感值 3.3 μH,公差 ±20%,采用色环标识,封装为插件型(D7.5 × L10 mm)。该器件面向功率滤波及开关电源领域,能在较高直流电流下保持较低直流电阻,适用于需要较高电流承载能力的传统插件电路。

二、主要规格与电气特性

  • 电感值:3.3 μH(±20%,实际范围约 2.64 – 3.96 μH)
  • 额定电流(Ir):4.9 A
  • 饱和电流(Isat):5.5 A(磁饱和点,超过此电流电感显著下降)
  • 直流电阻(DCR):15.5 mΩ
  • 类型:工字电感(插件)
  • 封装尺寸:D7.5 × L10 mm
  • 标识方式:色环/插件标记

功耗示例(用于热管理参考):

  • 在额定电流 4.9 A 下的铜损约为 P = I^2 × DCR ≈ 4.9^2 × 0.0155 ≈ 0.37 W;
  • 在饱和电流 5.5 A 下的铜损约为 0.47 W。实际损耗还与纹波电流、占空比及环境散热条件有关。

三、性能特点与典型应用

  • 优势:高电流承载、较低 DCR、结构稳固、易于手工焊接与维护;
  • 适用场景:DC-DC 降压/升压模块输入输出滤波、功率滤波器、开关电源电感、车载电子及工业控制电路的电流滤波与储能;
  • 注意事项:±20% 容差适合对精度要求不高的场合;若电感稳定性或温度系数要求严格,应考虑更高精度或贴片解决方案。

四、选型与热管理建议

  • 留有余量:工作电流建议低于额定电流以避免过热和磁饱和,通常取额定电流的 70–90% 作为设计参考;
  • 考虑纹波:开关电源中电感承受直流与交流纹波合成电流,需按有效值计算热损耗;
  • 散热措施:若预期损耗接近 0.3–0.5 W,应保证良好通风或在附近配置散热面/铜箔以扩散热量;
  • 验证测试:建议做温升、饱和特性和长期循环可靠性测试以确认实际系统表现。

五、安装与可靠性要点

  • 焊接:插件式,适合波峰或手工焊;注意避免长时间高温直焊,焊接后应进行清洗以防残留助焊剂;
  • 机械固定:封装尺寸 D7.5×L10 mm,安装时注意引脚剪裁与绝缘间距,保证抗振动性能;
  • 存储:避免潮湿、高温环境,常温干燥保存,防止磁芯损伤或引脚氧化。

六、采购与替代建议

  • 型号信息:PDPTAT0608-3R3M,品牌 PROD(谱罗德),描述:色环/插件电感 5.5A 3.3 μH ±20% 额定 4.9A;
  • 选型要点:若需更窄公差、更低 DCR 或更高 Isat,可检索“3.3 μH power through-hole inductor, DCR < 15 mΩ, Isat > 5 A”作为替代;
  • 测试要求:采购时确认 L、DCR、Isat、外形尺寸和焊接兼容性,并索取样品进行系统验证。

如需我根据具体应用(例如某型号的降压转换器、特定纹波电流和工作频率)计算电感电流有效值、温升估算或给出更精确的选型建议,可提供工作条件与电路参数,我会进一步协助。

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
