PDPMAA1712-100MP 产品概述
一、主要参数概览
- 型号：PDPMAA1712-100MP（谱罗德 PROD）
- 电感值：10 μH，公差 ±20%
- 额定电流（Irms/连续）：24 A
- 饱和电流（Isat）：25 A（典型，达到此电流时电感量显著降低）
- 直流电阻（DCR）：5.5 mΩ
- 封装/安装形式：插件（通孔），引脚间距 P = 13 mm
二、产品特点
- 适用于高电流直流电源场合：24 A 额定电流和较高的 Isat 使其能承受较大的负载电流冲击，适合中高功率模块的输出滤波。
- 高功率密度：在体积受限的通孔方案中提供较大电感量和电流承载能力。
- 稳定性考虑：±20% 公差适用于一般功率滤波与储能场合，需结合工作温度和直流偏置考察实际电感值。
三、典型应用
- DC-DC 降压（Buck）转换器的输出滤波电感
- 服务器、通信电源及多相电源模块的功率环路
- 工业驱动、LED 驱动及大电流稳压模块
- 高电流充电设备和电源管理模块
四、选型与设计要点
- 电流与耗散：在额定24 A 连续时，DCR = 5.5 mΩ，会产生约 P = I^2·R = 24^2 × 0.0055 ≈ 3.17 W 的铜损。该损耗对温升和长期可靠性影响显著，需评估散热条件并视情况进行电流降额或选用更低 DCR 的产品。
- 饱和裕量：Isat = 25 A 表示接近此电流时电感量将下降，设计中应留有裕量以避免工作点进入饱和区，尤其在浪涌或短路条件下。
- 纹波电流与匝间损耗：紋波电流大小由拓扑、开关频率和电感值决定。设计时用 ΔI = (Vin − Vout)·D / (L·f_s)（对降压拓扑）估算并验证电感在工作频率下的损耗与温升。
- 直流偏置影响：高直流偏置电流会降低实际电感量，需在目标电流下查验电感特性曲线或进行样品测试。
五、热管理与可靠性
- 由于在高电流下铜损较大，建议布局上保证良好散热通道：加大焊盘、使用厚铜 PCB、靠近散热器或空气对流良好的区域布置。
- 推荐在实际工作温度下做电感温升测试并据此进行电流降额或改变布局。
- 通孔结构适合波峰/手工焊接，但高温回流与焊接工艺需按厂方焊接规范执行，避免机械应力和焊点疲劳。
六、封装与焊接建议
- 引脚间距 P = 13 mm，通孔插件，适配常见通孔 PCB 布局；波峰焊和手工焊接均可，回流需确认温度曲线与材料可靠性。
- 安装时注意磁性元件周围的敏感器件和磁场耦合问题，必要时留出足够间距或采用屏蔽措施。
七、使用建议小结
PDPMAA1712-100MP 适合要求较高电流承载能力的功率滤波场合，其 10 μH/24 A 的规格在多种电源拓扑中具有实用价值。但需重视 DCR 引起的铜损（在满载时约 3.17 W），并在电路设计中做好散热与电流裕量评估。最终选型前建议获取厂方完整数据表并进行样品验证（电感-电流曲线、温升测试和绕组耐压等）。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
