PSPHAQ127-100M 产品概述
一、产品简介
PSPHAQ127-100M 是谱罗德（PROD）推出的一款功率型贴片电感，额定电流 6.5A，电感值 10µH，公差 ±20%，直流电阻（DCR）约 22mΩ，饱和电流（Isat）6.5A。封装为 SMD 形式，外形尺寸 12×12 mm，适合高电流、紧凑空间的电源滤波与储能应用。
二、主要电气参数与意义
- 电感值：10µH ±20%（初步设计取值，实际工作时随频率与直流偏置变化）；
- 额定电流/饱和电流：6.5A（连续工作参考值，Isat=6.5A 表示在该电流下电感值会明显下降或达到饱和）；
- DCR：22mΩ（影响效率与发热，参考耗散功率 P = I^2·DCR，6.5A 时 P ≈ 0.93W）。
注意：由于 Isat 与额定电流相同，器件在接近额定电流时已无太多裕度，设计时建议留有安全余量以避免磁饱和导致电感值骤降。
三、结构与封装特点
12×12 mm SMD 大尺寸封装提供较大的导磁体积与导流截面，利于高电流承载与散热。常见为铁粉或磁性粉芯/铁氧体材料，兼顾直流偏置性能与高频损耗。SMD 封装利于自动化贴装与回流焊流程。
四、典型应用场景
适合用于：
- 降压（Buck）开关稳压器电感；
- 电源模块与电源管理（PMIC）中的滤波储能；
- LED 驱动、高功率电池管理系统与工控电源；
- 需要高纹波电流承载但空间受限的场合。
五、选型与使用建议
- 预留裕量：建议工作电流不超过额定电流的 70–80% 以避免饱和与过高发热；
- 考虑直流偏置：电感在有 DC 偏置时会下降，应查看或测量 L(I) 曲线；
- 关注频率特性与损耗：高开关频率场合需评估铁损与涡流损耗；
- DCR 影响效率：计算功率损耗并设计散热或热沉措施。
六、PCB 布局与焊接注意
- 尽量缩短电感与开关管、电容之间的环路，减小寄生电感与 EMI；
- 在大电流回路下采用较宽铜箔与过孔/热vias 提升散热能力；
- 遵循器件回流焊温度曲线，避免过长保温导致磁性材料退磁或结构损伤。
七、可靠性与测试建议
建议在样机阶段进行：电感值随直流电流的测量、DCR 与温升测试、振动与热循环可靠性验证、在目标频率下的损耗和效率评估，以确认满足系统需求。
八、结论
PSPHAQ127-100M 提供了 10µH/6.5A 的功率电感方案，适合中高电流的电源滤波与储能应用。但由于 Isat 与额定电流相等，设计时应留有电流裕度并关注 DCR 带来的热损失与效率影响。最终选型仍建议参考完整数据手册和实际 L(I)、温升测试结果。

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.
