PSPHAQ127-101M 产品概述
一、产品简介
PSPHAQ127-101M 是谱罗德（PROD）推出的一款表面贴装功率电感，额定电流与饱和性能针对中低功率开关电源和滤波场合优化。器件为 SMD 结构，外形尺寸 12 × 12 mm，体积小巧，便于自动贴装与回流焊加工，适合工业、通信和消费类电子的电源前端与 EMI 抑制设计。
二、主要规格与参数
- 电感值：100 µH
- 精度（公差）：±20%
- 额定电流（Irated）：1.7 A（建议长期工作电流）
- 饱和电流（Isat）：2.2 A（直流偏置下电感显著下降前的临界值）
- 直流电阻（DCR）：约 220 mΩ
- 封装形式：SMD，尺寸 12×12 mm
以上参数为典型规格，实际应用中电感值会随直流偏置和温度有所变化，设计时应留有裕量。
三、性能特点
- 大电感值：100 µH 适合用于低频滤波与能量储存，能显著抑制开关噪声和输出纹波。
- 合理电流等级：1.7 A 的额定电流配合 2.2 A 的饱和电流，适合中等电流的降压/升压模块和后端滤波。
- 较高 DCR：约 220 mΩ，在选择时需平衡效率与电感值，DCR 较高将导致较大的 I^2R 损耗和发热。
- SMD 封装：12×12 mm 的标准贴片结构，利于电路板布局与热管理。
四、典型应用场景
- 开关电源（DC-DC 降压/升压转换器）的功率电感或输出滤波电感；
- 逆变器或电机驱动的辅助滤波电感；
- EMI 抑制与输入端 LC 滤波；
- 各类嵌入式设备、通信设备和工业控制器的电源模块。
五、选型与使用建议
- 工作电流裕量：长期工作电流建议不超过额定电流 1.7 A，以减少温升并延长寿命；峰值或瞬态电流应低于 Isat 2.2 A，避免电感值大幅下降。
- DCR 考量：若系统对效率敏感，需评估 220 mΩ 带来的损耗并考虑并联或选用更低 DCR 的型号。
- 直流偏置影响：在高直流偏置下电感值会下降，设计时应测量或参考厂商直流偏置特性曲线来确认实际电感值。
- 热管理：靠近发热器件应有热导铜层或热铜箔，必要时增加通孔或散热铜箔以降低结温。
六、封装与焊接建议
- 推荐采用标准回流焊工艺，遵循元件厂家给出的焊接温度曲线。
- PCB 布局：电感底部和附近应留足焊盘面积以保证良好热导与机械强度；开关节点布线尽量短且粗，减小回路面积以降低 EMI。
- 若需改善散热，可在电感附近设计热过孔连接到下层铜箔。
七、可靠性与注意事项
- 使用前确认电路最大峰值电流和温度环境，必要时进行热仿真或实测验证；
- 避免长期在额定电流附近运行，以防温升导致参数漂移或失效；
- 对于关键应用，建议向供应商索取样品并进行实际电流、温升及频率响应测试。
如需更详细的电流-电感特性曲线、温升数据或推荐封装焊盘图，请联系供应商或索取器件详尽数据手册。

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.
