PDMTAT044125-220MLU 产品概述
一、产品简介
PDMTAT044125-220MLU 是谱罗德（PROD）推出的一款环型色环插件电感，电感值为 22 µH，公差 ±20%。该器件为通过孔（DIP）封装，外形尺寸 16 × 14 × 8.5 mm，线径 0.8 mm，直流电阻（DCR）仅 15 mΩ，额定电流 7 A，适合大电流、低损耗的电源滤波与能量储存应用。
二、主要电气参数
- 电感值：22 µH（±20%）
- 额定电流：7 A（连续）
- 直流电阻（DCR）：15 mΩ
- 线径：0.8 mm
- 类型：环型电感 / 色环 / 插件
- 封装尺寸：DIP, 16 × 14 × 8.5 mm
三、产品特性
- 低 DCR：15 mΩ 有利于降低铜损与发热，提高效率。
- 大电流承载：额定 7 A，适用于中高电流路径。
- 环形结构：磁路集中，漏磁小，适合并排布置且对周围元件影响有限。
- 插件封装：便于手工或波峰焊装配与维修，适合快速样机验证与中小批量生产。
四、典型应用场景
- 开关电源（SMPS）输入/输出滤波
- DC-DC 降压/升压转换器的能量储存与滤波环节
- LED 驱动电源、汽车电子供电模块
- 电源 EMI 抑制与共模/差模滤波电路（视电路拓扑）
- 大电流滤波和去耦场合
五、选型与注意事项
- 电流裕度：建议在实际设计中对额定电流做适当降额（例如 80%）以减少温升和磁饱和风险。
- 温升与散热：虽然 DCR 低，但在接近额定电流工作时仍会产生热量，应考虑电路板散热与周边器件耐温性。
- 工作频率：该类环型电感更适合低频至中频（开关电源常见几十 kHz—数百 kHz）场景，具体频率响应应通过实测验证。
- 焊接建议：采用常规波峰或手工焊接工艺，避免长时间高温烘烤以免影响绕组漆包线或绝缘。
六、储存与使用建议
- 储存于干燥、无腐蚀性气体的环境，避免潮湿和强酸碱环境。
- 安装时避免对引脚施加过大机械应力，防止外形变形或内部绕组损伤。
- 在设计时预留合适的走线与间距，减小寄生电阻与热耦合影响。
本产品 PDMTAT044125-220MLU 以其低阻抗、大电流承载能力和插件方便性的组合，适合电源滤波和功率管理类电路，是需要兼顾效率与可靠性的中高电流应用的理想选择。若需详细的电感频率特性曲线、饱和电流或温升测试数据，可联系谱罗德或提供样品进行评估测试。

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.
