PDPTAT0608-4R7M 产品概述

一、产品概述

PDPTAT0608-4R7M 为谱罗德(PROD)系列工字形插件电感,色环标识,封装尺寸 D7.5×L10mm,适用于中小功率开关电源与滤波电路。该器件以低直流电阻和较高电流承载能力为特点,适配苛刻的电流通断与纹波环境。

二、主要参数

  • 电感值:4.7 μH,公差 ±20%
  • 额定电流(Ir):4.6 A(连续使用参考值)
  • 饱和电流(Isat):4.8 A(磁通密度开始明显下降时)
  • 直流电阻(DCR):约 18 mΩ
  • 类型:工字电感(插件)
  • 封装:插件,尺寸 D7.5×L10 mm
  • 品牌:PROD(谱罗德)

三、特性与优势

  • 低 DCR(18 mΩ),在高电流条件下功耗小,能效高;
  • 额定电流与饱和电流接近,适合短时大电流脉冲或连续中等电流场合;
  • 插件式机械强度好,便于波峰/手工焊接与维修替换;
  • 工字结构利于磁路集中,体积与感量在小型封装中取得平衡。

四、典型应用

  • DC-DC 降压转换器(作为输出滤波电感);
  • LED 驱动与车载电子电源(对耐振动与热稳定性有要求的场合);
  • 电源输入滤波、纹波抑制及瞬态电流缓冲;
  • 各类工业控制与通信设备的电源模块。

五、选型与设计建议

  • 对持续导通电流尽量采用适当降额(建议工作电流不超过额定电流的 70%–90%),以降低温升与避免接近饱和区造成电感量下降;
  • 在有大纹波或脉冲电流场景下,关注纹波 RMS 电流导致的发热(可用 P≈I²·DCR 粗略估算);
  • 若系统对电感精度或温漂有严格要求,考虑选用公差更小或温度特性更优的替代型号;
  • 设计 PCB 时留出足够散热空间并避免近旁热源影响。

六、安装与可靠性建议

  • 插件焊接时应遵循焊接工艺规范,避免过长高温暴露;
  • 存储与使用环境避免潮湿、强腐蚀气体与过大振动;
  • 对于关键应用,建议进行实际电流/温升和磁饱和测试以验证可靠性。

若需更详细的电气特性曲线(磁通饱和曲线、频率响应、温升试验报告)或 3D 尺寸图与推荐插件孔径,请提供需求,我可根据谱罗德资料或样品测试结果进一步补充。

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
