PSTMAA3020-150MB — PROD（谱罗德）15µH 扁平线一体成型SMD电感 产品概述
一、产品简介
PSTMAA3020-150MB 为谱罗德（PROD）推出的一款小型化扁平线一体成型贴片电感，封装约3×3 mm，专为空间受限且需一定导流能力的电源与滤波应用设计。采用扁平线绕制并一体成型，兼顾磁性能和机械强度，适合自动贴装与回流焊工艺。
二、主要电气参数
- 电感值：15 µH（标称）
- 精度：±20%
- 额定电流：1.8 A（连续工作推荐值）
- 饱和电流（Isat）：2.6 A（磁饱和时电感显著下降）
- 直流电阻（DCR）：约 260 mΩ
- 封装形式：SMD，3×3 mm，扁平线一体成型
三、产品特性与优劣分析
优点：
- 体积小、适合高密度PCB布局；
- 扁平线结构在相同尺寸下有利于减小纹波电流与热量分散；
- 一体成型提高机械可靠性，利于自动化生产。
权衡点：
- DCR ~260 mΩ 在大电流场合产生的功耗和发热需考虑，若需更低DCR应选更大封装或不同材质产品；
- ±20% 精度适合电源滤波和一般功率应用，但对精密谐振回路需注意偏差。
四、选型与设计建议
- 工作电流通常建议低于额定电流1.8 A以控制温升并保证长期可靠性；短时脉冲可参考Isat 2.6 A但需留安全裕度。
- 若使用于开关电源，注意电感在工作点的实际电感值下降（由直流偏磁导致），建议在原理图仿真时输入饱和特性曲线或实际测量数据。
- 对于对功耗敏感的方案，计算I^2·DCR导致的功耗并评估散热路径。
五、PCB布局与焊接要点
- 尽量缩短与电感相连的电流回路，减小寄生电感与电阻；两个焊盘对称放置，焊盘需保证足够的焊锡端面以获得良好热和电连接。
- 建议靠近大电流源（如MOSFET、电感入/出端）放置，并配合适当的铜箔散热。
- 遵循常规无铅回流工艺，避免在装配过程中对器件施加过大机械应力。
六、典型应用
- 输入或输出LC滤波器、直流-直流降压/升压转换器中的电感元件、功率隔离与纹波抑制、便携设备与通信终端的电源模组等。
七、检验与储存建议
- 推荐在最终PCB上测量实际电感值、DCR与温升，验证满足系统需求；搬运与贴装过程中避免过度弯曲或挤压。
- 常规干燥、无腐蚀环境储存，遵循电子元器件静电防护和潮湿敏感器件处理注意事项。
如需进一步数据（如频率特性、温度漂移曲线、饱和特性曲线或推荐封装焊盘尺寸图），可提供样品或询问生产商技术资料表以获得完整可靠的工程数据。

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.
