BOURNS SRP7028A-220M是一款专为汽车电子及高可靠性电源场景设计的屏蔽绕线功率电感,具备稳定的电性能、宽温适配性及车规级可靠性,可满足多种中高频功率电路的滤波与储能需求。
该电感的关键技术参数明确,可支撑电路设计的精准选型:
采用屏蔽绕线设计,可有效抑制电磁干扰(EMI):既减少外部电磁信号对电感性能的影响,也降低自身磁场对周围电路的干扰,提升系统EMC兼容性,适合对电磁环境敏感的汽车电子场景。
羰基铁粉磁芯具有高磁导率、低高频损耗的特点,在100KHz中高频段表现稳定,Q值维持在20左右,可降低电源转换过程中的能量损耗,提升效率。
额定电流2A匹配多数车载电源、LED驱动等功率电路的负载需求;165mΩ的低DCR显著减少直流功耗,避免电感发热累积,延长电路使用寿命。
AEC-Q200车规认证证明其可在**-40℃~125℃**(汽车级典型温度范围)下稳定工作,能承受汽车环境中的振动、湿度变化等严苛条件,满足长期可靠性要求。
SRP7028A-220M主要适配对可靠性要求高的功率电路,核心场景包括:
AEC-Q200认证是汽车电子元器件的“准入门槛”,SRP7028A-220M通过该认证,证明其经过振动、温度循环、湿度等多项严苛测试,可在汽车全生命周期内稳定工作。
BOURNS作为全球领先的电子元器件制造商,具备成熟的绕线电感生产工艺,产品质量稳定、供货周期可控;同时提供完善的技术支持,可协助客户解决电路设计中的电感选型与应用问题。
采用非标准封装(通常为7mm×7mm×2.8mm尺寸),可适配特定PCB布局需求,避免与周边器件冲突,适合空间紧凑的汽车电子模块(如ECU、车载充电器)。
综上,BOURNS SRP7028A-220M是一款兼顾电性能、可靠性与适配性的车规功率电感,可广泛应用于汽车电子及高可靠性电源领域,满足多种中高频功率电路的设计需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
