PDPMAA1712-470MP — PROD（谱罗德） 14A 功率电感（插件）
一、产品概述
PDPMAA1712-470MP 是谱罗德（PROD）推出的一款插件式功率电感，标称电感值 47µH，公差 ±20%，适用于中高电流电源滤波与储能场合。额定电流 8A，饱和电流（Isat）14A，直流电阻（DCR）32mΩ，器件脚距 P=13mm，适合通过孔（THT）安装的电源电路方案。
二、主要规格参数
- 电感值：47µH（±20%）
- 额定电流：8A（长期允许通过电流，考虑温升与寿命需适当降额）
- 饱和电流：14A（超过此值电感量显著下降）
- 直流电阻：32mΩ（0.032Ω）
- 封装形式：插件（通过孔），脚距 P=13mm
- 品牌：PROD（谱罗德）
三、性能与特点
- 高电流承载能力：额定 8A，短时可承受接近 Isat 的峰值电流，适合电源滤波与能量传输。
- DCR 与功耗：在额定电流 8A 时，铜损约 P = I²·R = 8²·0.032 ≈ 2.05W，压降约 0.256V；需注意电感本体与周边器件的散热。
- 饱和特性：Isat 14A 表明在冲击或短路情况下仍有一定裕量，但超过 Isat 会导致电感急剧下降，应避免长时间超载。
- 插件结构便于手工焊接与波峰焊，适合维修与小批量开发。
四、典型应用
- 开关电源（低/中频 DC–DC 降压/升压）中的储能电感与输出滤波。
- LED 恒流驱动、电池管理与UPS、汽车电子（需确认振动与温度等级）中的电源滤波。
- EMI 滤波及电源入口处的噪声抑制（根据频率特性选择）。
五、使用与选型建议
- 若工作频率较高（数百 kHz 以上），应确认材料的频率响应与损耗，47µH 值偏大，可能影响环路动态；高频应用可考虑电感值更小或更低损耗的型号。
- 按照实际工作温度对额定电流降额（例如在高温或散热不足情况下降额 20–30%）。
- 计算系统功耗时同时考虑 DCR 导致的持续功耗与温升，必要时在布局上提供气流或散热片。
六、安装与热管理
- 插件脚距 13mm，请参考厂家推荐 PCB 孔位与焊盘尺寸，保证机械强度与焊点可靠性。
- 建议在电感周围保留空气流道或配合风扇，提高散热能力；对于长时间大电流工况，进行温升测试并确认寿命。
七、采购与检验
- 订购时请注明型号 PDPMAA1712-470MP、品牌 PROD，并向供应商索取完整 datasheet、温升曲线与材料说明（如需 RoHS/车规认证亦请确认）。
- 到货后建议进行外观、DCR、标称电感值与高电流负载测试（含温升与饱和特性验证）以保证与设计一致。
如需我帮您把该器件与您现有电路（工作频率、纹波电流、允许压降等）匹配并给出更详细的选型或替代件建议，请提供电路工作条件参数。

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.
