PROD PDPTAT0810-3R3M — 3.3µH 工字插件电感 产品概述

一、产品简介

PDPTAT0810-3R3M 是谱罗德(PROD)推出的一款径向引线工字电感,标称电感值 3.3µH,公差 ±20%(M)。该器件为插件色环式外观,适合传统通孔装配与手工/波峰焊工艺,适用于各类开关电源滤波与功率线圈场合。典型体积为 D9.5×L12mm,封装为径向引线(插件),便于板上垂直放置以节省空间并简化装配。

二、主要电气参数

  • 电感值:3.3µH ±20%
  • 额定电流(Irated):5.4A(连续允许电流)
  • 饱和电流(Isat):7A(在此电流下电感显著下降)
  • 直流电阻(DCR):≈13 mΩ
  • 类型:工字磁芯、色环标识、插件(径向引线)
  • 尺寸参考:D9.5×L12 mm(封装标注亦见 8×10 mm)

注:±20%(M)为常规电感公差,实际应用中需考虑温度、直流偏流及频率特性对有效电感的影响。

三、特性与优势

  • 高电流能力:5.4A 额定电流与 7A 饱和电流,使其适合中等功率 DC-DC 转换器与电源滤波使用。
  • 低 DCR:约 13 mΩ 的低直流电阻降低了 I²R 损耗,示例:在额定电流 5.4A 下,铜损约 I²·R ≈ 0.38 W。
  • 插件易装配:径向引线适合通孔 PCB,便于手工焊接、波峰焊及维修替换。
  • 体积小巧:紧凑外形适合空间受限的功率模块与板上过滤器设计。

四、典型应用场景

  • 开关稳压器(降压/升压转换器)电感线圈
  • 电源输入/输出滤波(LC 滤波器)与纹波抑制
  • LED 驱动电源、充电器、工业电源模块
  • EMI 抑制与功率总线隔离场合

五、设计与使用建议

  • 考虑直流偏置:在高直流电流下电感值会下降,接近或超过 Isat 时电感急剧减小,应保证工作电流留有裕量。
  • 损耗与发热:按示例计算的铜损(≈0.38 W)会导致升温,设计时需留有散热与温升裕度。
  • 高频特性:在开关频率(如几十至几百 kHz)下,感抗 X_L = 2πfL 随频率上升,可用于抑制纹波;但要关注绕组寄生电容及磁芯损耗。
  • 焊接工艺:插件式适用手工与波峰焊,焊接时避免过长高温暴露以防磁芯或绝缘材料老化。建议遵循通用元件焊接曲线,尽量减少直接加热时间。

六、机械与封装注意

  • 引线处理:如需弯脚,建议在靠近焊盘处轻曲,避免在靠近绕组处施加应力或拉力。
  • 安装高度与固定:在震动或冲击环境下,可在底部加环氧点固定以增强可靠性。
  • 检查占位与邻近元件间距,确保磁场与散热空间。

七、采购与检测建议

  • 订购型号:PDPTAT0810-3R3M(PROD / 谱罗德)—— “3R3” 表示 3.3µH,“M” 表示 ±20% 公差。
  • 到货检验:抽样测量电感值、DCR 与耐电流特性;在目标工作频率下进行纹波抑制验证。
  • 如需更严格公差或更低 DCR,请咨询厂商是否有相邻规格或定制版本。

本产品为通用型中大电流插件工字电感,适合多数中功率电源设计。设计时建议结合实际负载波形与频率做样机验证,以确保在目标工况下的电感值、损耗与温升均满足要求。若需更详细的频率响应、温升曲线或 3D 尺寸图,可向供应商获取数据手册或样品测试报告。

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
