PDMTAT044125-101MWU 产品概述
一 产品简介
PDMTAT044125-101MWU 为谱罗德（PROD）系列环形插件电感，标称电感值 100 μH，公差 ±20%，额定直流电流 3A，直流电阻（DCR）约 70 mΩ。外形为环形（色环识别），插件封装，外径约 D=14.5 mm，适用于中低频能量滤波与电源去耦场合。
二 主要性能参数
- 电感值：100 μH ±20%
- 额定电流：3 A（最大连续工作电流，具体请依据实际环境温升与饱和特性做留余）
- 直流电阻（DCR）：≈70 mΩ
- 封装形式：插件（Through-hole），外径 D=14.5 mm
- 类型：环形电感（色环标识，便于型号区分）
三 特性与设计要点
- 由于 DCR≈70 mΩ，在满载 3 A 时理论铜耗约为 P = I²·R = 9·0.07 ≈ 0.63 W，器件会出现明显温升。若用于长期连续工作，应考虑电流余量或散热措施（建议连续工作电流按 70%–80% 余量选型）。
- 环形结构具有较好的磁通闭合性，较低的辐射与漏磁，但具体饱和电流与频率响应须参考厂方数据表。
- ±20% 的公差在滤波应用中为常规等级，设计时需留意并联/串联网络对总电感容差的影响。
四 典型应用场景
- 开关电源（SMPS）输入/输出侧滤波
- DC-DC 转换器能量存储与纹波抑制
- EMI/EMC 抑制电路与共模/差模滤波（视连接方式）
- 音频电源滤波、工业控制等需较大电流的低频滤波场景
五 安装与工艺建议
- 插件封装适合波峰或回流后手工焊接工艺，焊接时注意控制温度与时长，避免长期高温引起漆包线老化。
- 保持绕组两端良好焊点，避免过度机械应力导致引脚松动或断裂。
- 器件周围留足空间以利散热，若应用在高温环境应提升额定电流裕量或加装散热结构。
六 选型与测试建议
- 在实际电路中建议做热测，测量在额定电流或预期工作电流下的温升与电感下降（饱和特性）。
- 测量电感值时可采用 LCR 表在标准频率（如 100 kHz）及小信号电压下测定，并与标称值 ±20% 对比。
- 若用于高频开关场景，关注自谐频率（SRF）与频率响应曲线，必要时向供应商索取完整数据表。
七 质量与合规
- 采购时请向供货方确认详细性能曲线、可靠性测试报告及环保合规（如 RoHS）证明。谱罗德品牌在市场上具备一定知名度，但不同批次与用途建议做来料检验与样机验证。
总结：PDMTAT044125-101MWU 是一款适合中低频大电流滤波的插件环形电感，优势在于磁路闭合好、漏磁小；选型时需重点考虑 DCR 引起的热耗与实际工作电流的余量，以保证长期可靠运行。若需更详细的频率特性、饱和电流和温升曲线，可联系供应商获取完整数据手册。

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.
