PSPMAA1040H-100M-ANP 产品概述
一、产品简介
PSPMAA1040H-100M-ANP 为谱罗德（PROD）系列表面贴装功率电感，标称电感值 10 μH，公差 ±20%。本器件采用 SMD 封装，外形尺寸约 11 × 10 mm，针对中等功率开关电源与DC-DC变换器的滤波与储能场合设计，额定电流 7 A，饱和电流(Isat) 9 A，直流电阻 (DCR) 典型值 45 mΩ。
二、主要特性
- 额定电流高，适合 5–9 A 级别电流回路使用；
- 较低 DCR，有利于降低功率损耗与温升；
- Isat 明确，保证在短时过载或启动瞬态下电感不致显著降磁；
- SMD 封装利于自动化贴装与体积受限的板级布局。
三、电气参数（摘要）
- 电感：10 μH ±20%（常温直流条件）；
- 额定电流：7 A（连续工作时允许通过的最大电流，过流会导致温升超限）；
- 饱和电流 Isat：9 A（在该电流下电感量降至公称值的指定比率以下，通常用于短时峰值评估）；
- 直流电阻 DCR：45 mΩ（影响纹波损耗与效率）。
四、典型应用
- 中小功率降压（Buck）与升压（Boost）DC-DC 转换器；
- 电池供电系统与电机驱动的滤波与储能；
- 点合并供电/多相电源模块中作为每相电感；
- 工业与通信设备的电源前端滤波。
五、选型与使用建议
- 留出电流裕度：长期工作电流建议低于额定电流 80–90%，以控制温升与延长寿命；峰值电流应低于 Isat。
- 注意直流偏置效应：在加直流偏流时电感值会下降，设计时按额定工作点测得的实际电感选型。
- 热管理：DCR 引起的铜损随电流平方增长，需评估板上散热与环境温度。
- 电感公差 ±20% 要求系统有足够容差，若环路滤波或共振点敏感，应考虑更精密规格或并联/级联方案。
六、封装与可靠性
- SMD 11×10 mm 尺寸适合自动贴装与回流焊；推荐遵循供应商的回流曲线以避免磁芯或粘接材料受损。
- 采用合适焊盘与过孔布局可改善热量传导与机械强度，必要时在散热密集区并用散热铜箔。
七、典型电路与布局注意事项
- 将电感尽量靠近开关器件或输出电容布置，缩短高频回路环路面积以减小 EMI；
- 输出电容靠近负载端并行放置，搭配合适的 RC 屏蔽以控制尖峰；
- 对于多相设计，注意相间配合与磁场耦合影响，避免相邻电感过近造成互感异常。
八、结论
PSPMAA1040H-100M-ANP 是一款面向中等功率电源的 SMD 功率电感，具有较高额定电流和明确的饱和指标，适用于 DC-DC 转换器与滤波场景。选型时应考虑电感偏置、DCR 导致的损耗与封装热管理，合理留余量可确保长期可靠运行。若需更严格的电感稳定性或更低 DCR，可联系供应商获取系列替代型号与样品测试数据。

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.
