PSPNAQ3015-100M 产品概述
一、产品简介
PSPNAQ3015-100M 是谱罗德（PROD）推出的一款功率电感，额定电感值为 10 μH，公差 ±20%。器件为表面贴装（SMD）封装，外形尺寸 3×3 mm，针对紧凑型开关电源和电源滤波场合优化设计，适合中低电流的能量储存与滤波应用。
二、电性能要点
- 感值：10 μH ±20%，适用于需要中等电感量的电源回路。
- 额定电流（Irated）：860 mA，建议在此值以下长期工作以保证稳定性和低温升。
- 饱和电流（Isat）：970 mA，当电流接近或超过该值时，电感会发生磁饱和，感值显著下降，影响电源性能。
- 直流电阻（DCR）：225 mΩ，DCR 直接决定了 I^2R 损耗；例如在 0.86 A 时，铜损约为 0.86^2×0.225 ≈ 0.166 W。
这些参数综合决定器件在开关频率、纹波电流以及热管理方面的表现。
三、典型应用场景
- 降压（Buck）开关转换器的储能电感与输出滤波。
- 电源输入/输出端的电磁干扰（EMI）和纹波抑制。
- 电池供电设备、便携式设备的去耦与稳压模块。
- 各类中低功率电源模块、模块化电源解决方案中的紧凑型滤波器单元。
四、选型与使用建议
- 工作电流最好留有裕量：长期工作电流建议低于额定电流 860 mA，以减小温升并避免接近饱和区。
- 注意 DCR 带来的功耗与热量：设计散热或在 PCB 布局中考虑热传导路径，避免局部过热导致性能退化。
- 考虑电感公差 ±20% 对谐振频率与纹波电流的影响，在滤波或谐振电路中应预留容差空间。
- 饱和特性：在大电流瞬态时要防止进入饱和区（Isat = 970 mA），若系统可能出现短时冲击电流，应选择更大电流规格或并联多颗电感。
五、封装与焊接注意
SMD 3×3 mm 紧凑封装利于高密度 PCB 布局。推荐在布局时为电感留下适当的焊盘面积与热沉路径，靠近电源管脚以缩短回路长度，减小寄生电感。采用常规无铅回流工艺时，应参照厂方资料确认焊接温度曲线与可焊性，避免超出温度极限导致磁性材料或粘接剂性能变化。
六、验收与可靠性建议
- 上板后建议进行阻抗或感值测量，以验证实际装配后参数变化。
- 运行验证应包括热敏测试与长期老化测试，确认在目标环境温度与负载条件下的稳定性。
- 对于关键应用，建议与供应商确认电感随温度、频率的特性曲线和机械可靠性数据。
结语：PSPNAQ3015-100M 提供了体积小、适用于中低电流功率回路的解决方案。在实际设计中请结合系统电流峰值、允许功耗与热设计进行综合评估，必要时参考厂方完整数据手册以获得更详细的电气和可靠性参数。

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.
