PSPMAA0705L-6R5M是谱罗德(PROD)推出的中功率表面贴装(SMD)扁平线电感,针对高密度PCB布局、中功率电源转换场景优化设计,兼具低损耗、高电流承载能力与小尺寸优势,可广泛适配消费电子、车载及工业控制等领域的电源电路需求。
该电感标称电感值为6.5μH,精度±20%,满足大多数功率电路对电感偏差的要求。采用扁平线绕制工艺,相比传统圆形线电感,其电感值在宽频率范围(100kHz~1MHz)内稳定性更高——高频下趋肤效应影响更小,避免了电感值随频率上升而下降的问题,适配主流开关电源频率。
两者数值一致,意味着在6A连续工作电流下,电感仍能保持稳定性能输出,不会因饱和导致电路纹波增大、效率降低,适合中功率负载的持续供电场景(如车载充电器、笔记本电源模块)。
直流电阻(DCR)仅25mΩ,得益于扁平线的大线径与紧密绕制工艺,有效降低了电流热损耗。以6A工作电流为例,单电感热损耗为:
$$I^2R = 6^2 \times 0.025 = 0.9W$$
远低于同电流等级的传统绕线电感,可显著提升电源转换效率(如DC-DC降压电路效率提升2%~3%),减少系统散热需求。
采用SMD表面贴装封装,实际尺寸为7×6.9mm(低profile设计,厚度约3mm),可直接集成于高密度PCB板中,适配笔记本、平板等小型化产品的空间限制;同时支持回流焊、波峰焊等自动化生产工艺,提升生产效率。
基于功率电感行业标准,该产品支持**-40℃~125℃**宽温工作,可满足工业控制(如PLC)、车载电子(如仪表盘)等极端环境的稳定运行需求。
PSPMAA0705L-6R5M通过扁平线工艺与小尺寸设计的结合,平衡了功率承载与空间需求,是中功率电源电路的高性价比选型。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
