BOURNS作为全球被动电子元件领域的知名厂商,其SRP1038A系列功率电感针对汽车电子、工业电源等严苛场景设计,SRP1038A-150M 是该系列中兼顾电流承载能力与小体积的典型型号,凭借车规级可靠性与优异电气性能,成为中功率电路的优选元件。
该电感定位于车规级中功率贴片电感,核心设计围绕三大需求展开:
电感值为15μH ±20%,覆盖中功率DC-DC转换器、电机驱动等电路的典型电感需求范围;电感精度±20%符合功率电感的常规设计标准,可满足大多数电源电路的滤波、储能要求。
直流电阻(DCR)仅45mΩ,属于同功率等级电感中的低损耗水平:低DCR可显著降低电流通过时的功率损耗(P=I²R),减少设备发热,提升电源转换效率,尤其适合车载电源等对效率敏感的场景。
采用SMD(表面贴装)封装,外形尺寸为10×11mm(长×宽),高度符合车载电子设备的PCB布局限制;贴片封装适配自动化贴装工艺,可降低生产制造成本,提高生产效率。
电感采用磁芯绕线结构,磁芯材料具备低磁损、高饱和磁通密度特性,确保在大电流下仍能保持稳定的电感性能;绕线工艺优化减少了寄生参数(如分布电容),提升了电路的高频响应能力。
SRP1038A-150M的性能参数与车规认证使其在以下场景中表现优异:
通过AEC-Q200认证,意味着该电感已通过汽车电子环境下的严苛测试:包括-40℃至125℃的温度循环、振动(10g~2000Hz)、湿度(85℃/85%RH)、盐雾等,可稳定工作于汽车发动机舱、仪表板等不同环境区域。
符合RoHS无铅环保标准,不含铅、镉、汞等有害物质,适配全球电子市场的环保要求。
综上,BOURNS SRP1038A-150M功率电感凭借车规级可靠性、优异的电流承载能力与低损耗特性,成为车载电子、工业电源等中功率电路的高性价比选型,可有效满足严苛环境下的稳定工作需求。

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.
