PDMTAT044125-220MWU 产品概述
一、产品简介
PDMTAT044125-220MWU 是谱罗德（PROD）出品的一款插件环形电感，电感量为 22 μH，公差 ±20%，额定电流 8A，直流电阻（DCR）约 15 mΩ。外形为环型（Toroidal），引脚式插件封装，外径约 D=14.5 mm，线径 0.8 mm（约等同于 AWG20），且采用色环标识，便于快速识别型号和参数，适合中等功率的开关电源和滤波场合。
二、主要参数
- 品牌：PROD（谱罗德）
- 型号：PDMTAT044125-220MWU
- 电感值：22 μH ±20%
- 额定电流：8 A（直流连续）
- 直流电阻（DCR）：15 mΩ（典型）
- 结构类型：环型电感（插件/Through-hole）
- 线径：0.8 mm（约 AWG20）
- 封装直径：D = 14.5 mm
- 标识方式：色环/色带标注
三、性能与特性
- 低 DCR、低铜损：15 mΩ 的直流电阻在 8A 级别下有利于降低 I²R 损耗，提升效率。
- 环形磁芯：环形结构漏磁小、磁路闭合好，适合高密度 PCB 布局并减少对周边元件的干扰。
- 插件封装：便于手工或波峰/回流焊接作业，适合中小批量装配与维修替换。
- 标准公差：±20% 满足多数功率滤波与储能需求；实际电感在有直流偏流时会出现磁心饱和效应，应关注工作点。
四、典型应用场景
- DC-DC 降压/升压转换器主电感或输出滤波电感
- 电源输入滤波与去耦（降低纹波与 EMI）
- LED 驱动、电机驱动及其他中等功率开关电源模块
- 工业与消费类设备的电源模块替换件
五、装配与使用注意事项
- 推荐在出厂额定电流下验证温升与电感衰减，连续工作时建议按 70%~80% 的余量进行选型以控制发热与避免磁心饱和。
- 由于电感标称值有 ±20% 公差，关键滤波和谐振电路请以实测值为准并留有调整余地。
- 环型电感对安装方向不敏感，但应注意与磁敏器件保持适当间距以规避磁耦合问题。
- 插件引脚建议使用适配孔距和焊盘尺寸，波峰或回流焊时遵循焊料和温度曲线，避免过热影响绝缘漆层或磁芯。
六、选型建议
- 若设备工作在较高开关频率或要求更小纹波，可优先考虑 DCR 更低或更高额定电流的同系列品种；
- 关注磁心材料与饱和电流特性，如果电路存在较大直流偏流（DC bias），请向供应商确认在相应电流下的电感衰减曲线；
- 批量采购或用于关键电源时，建议索取样品进行实测（温升、效率、磁饱和）以验证实际性能。
如需详细规格书（电感与电流下的频率响应、温升曲线、尺寸图及引脚布局图）或量产报价，请告知采购数量与使用工况，我可协助获取供应商资料并给出更精准的选型建议。

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.
