PDMTAT044125-470MLU 产品概述
一、产品概况
PDMTAT044125-470MLU 是谱罗德（PROD）推出的一款环型色环插件电感，电感值 47 μH，公差 ±20%，额定电流 4.5 A，直流电阻（DCR）35 mΩ。封装为 DIP 型，外形尺寸 16 × 14 × 8.5 mm，导线线径 0.55 mm，适用于中小功率电源滤波、共模/差模抑制及开关电源环路的能量储存与滤波应用。
二、主要技术参数
- 型号：PDMTAT044125-470MLU
- 品牌：PROD（谱罗德）
- 电感值：47 μH ±20%
- 额定电流：4.5 A（连续电流能力）
- 直流电阻（DCR）：35 mΩ
- 类型：环型电感（色环/插件）
- 引线直径：0.55 mm
- 封装尺寸：16 × 14 × 8.5 mm（DIP）
三、性能要点与工程含义
- 电感值与公差：47 μH ±20% 适合低频滤波与输出滤波器设计，公差偏宽，设计时应以最差情况（-20%）考虑电感量变化对截止频率和环路相位裕度的影响。
- 电流与 DCR：额定电流 4.5 A 表明在该电流下电感能保持工作不饱和；DCR 35 mΩ 在满载时电压降约 0.16 V（4.5 A × 0.035 Ω），功耗约 0.71 W（I^2·R），因此需考虑散热与功耗对温升的影响。
- 环型结构：环型磁芯有利于磁通闭合，漏磁小，对邻近元件干扰低，适合密集布局的电源板。
四、典型应用
- 开关电源（DC-DC）输出滤波或储能电感（尤其降压型）
- 输入侧滤波与 EMI 抑制电路
- 功率滤波模块、车载电子、家用电器及工业控制电源
- 需要良好抗饱和特性与较高直流载流能力的场合
五、封装与安装建议
- 采用插件（DIP）安装，建议按照封装尺寸预留标准孔径与间距，保证焊接可靠性。
- 焊接与回流：通过孔焊接或波峰焊时应控制温度和时间，避免过热导致漆包线绝缘受损或机械变形。建议遵循供应商的焊接工艺规范。
- 布局：为降低磁耦合与噪声干扰，敏感信号线与高电流回路保持适当间距；若多颗电感并列，应考虑相互间距以减少磁耦合。
六、热管理与选型建议
- 满载功耗接近 0.7 W，若长期工作在接近额定电流，应评估周围散热条件及环境温度，必要时留出通风或散热空间。
- 若电路对电感精度敏感或工作温度范围宽，建议在样机阶段测量实际电感随温度/电流的变化，确认饱和电流与热阻指标满足要求。
- 设计裕量：考虑 ±20% 公差及电流产生的温升，若需更严格的稳定性或更低损耗，可选用低 DCR 或更高额定电流的替代品。
如需完整数据手册、磁芯材料说明、浪涌/饱和测试曲线或封装图纸，可提供，我将基于具体测试参数给出更精确的热耗与电磁兼容（EMC）建议。

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.
