PSPHAQ127-151M 产品概述
一、产品简介
PSPHAQ127-151M 是谱罗德（PROD）推出的一款功率型贴片电感，标称电感值为 150µH，公差 ±20%。该器件为 SMD 封装，外形尺寸 12×12×8.0 mm，额定电流与饱和电流均为 1.9A，直流电阻（DCR）约 280 mΩ，适合中低频电源滤波与储能应用。
二、主要性能与特点
- 电感值：150 µH，允许偏差 ±20%；
- 额定电流（Irms）：1.9 A；磁饱和电流（Isat）：1.9 A（在大电流下应注意感量下降）；
- 直流电阻：约 280 mΩ，利于判断功耗与发热；
- 封装形式：SMD，尺寸 12×12×8.0 mm，便于表面贴装生产；
- 适用于开关电源的电感储能、输入输出滤波、EMI 抑制等场景；
- 结构稳固、耐焊接工艺，适配常规回流焊流程。
三、典型应用
- DC-DC 降压/升压转换器（中小功率点位负载）；
- 开关电源输入/输出滤波电路；
- 电机驱动与电源管理模块；
- 工业控制、通信设备、消费类电子中对中等电流滤波需求的场合。
四、选型与使用建议
- 电流余量：建议长期工作电流不超过额定电流的 70%–80%，以降低发热并延长可靠性；间歇或短脉冲可接近额定值，但需评估温升；
- 直流偏置影响：高 DC 偏置会使实际电感值下降，设计时应考虑此项衰减；必要时做实测曲线确认；
- 热管理：DCR 导致的损耗随电流平方增长，应评估环境温度与散热条件，合理布局散热铜箔；
- PCB 布局：电感两端走短且宽的走线以降低寄生阻抗；靠近开关元件放置可减小环路面积；
- 焊接工艺：遵循通用 SMD 回流焊规范，避免过度机械应力及重复加热。
五、可靠性与测试建议
- 出厂前建议进行电感值、DCR、耐温与振动测试以验证一致性；
- 生产验证阶段可做温升测试、冲击与湿热实验，确保在目标应用环境下的长期可靠性。
六、包装与采购
产品以 SMD 形式供应，适用于自动贴片与回流焊工艺。订购时请注明型号 PSPHAQ127-151M、数量与交付形式（卷带/托盘等），并向谱罗德（PROD）或其授权分销渠道索取样品与详细规格书、SIP/PCB 建议焊盘图以便设计验证。
总结：PSPHAQ127-151M 为一款中等电流、较高电感值的 SMD 功率电感，适合对滤波与能量储存有要求的中小功率电源设计。选型时关注 DC 偏置下的电感衰减、DCR 导致的功耗与热管理，以保证电路稳定与可靠。

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.
