BOURNS SRP7028A-220M 功率电感产品概述

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。

一、核心参数规格

该电感的关键技术参数明确,可支撑电路设计的精准选型:

  • 电感值与精度:标称电感值22μH,允许偏差±20%,覆盖常规功率电路对电感量的基本要求;
  • 电流特性:额定连续工作电流2A,可稳定承载常规功率负载;饱和电流3.5A(电感值下降30%的临界电流),提供过载裕量,避免电路瞬态突变时电感饱和导致性能波动;
  • 直流电阻(DCR):直流条件下165mΩ,有效降低直流损耗,减少发热并提升电源转换效率;
  • 频率特性:100KHz工作频率下Q值为20,表明在中高频段磁芯损耗低、电感性能稳定;
  • 材料与认证:采用羰基铁粉磁芯,具备高磁导率与低损耗特性;通过AEC-Q200车规认证,符合汽车电子严苛环境要求;
  • 封装与品牌:非标准封装(适配特定PCB布局),由全球知名元器件厂商BOURNS生产。

二、技术特性解析

1. 屏蔽绕线结构

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。

2. 羰基铁粉磁芯优势

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。

3. 电流与损耗平衡

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。

4. 宽温可靠性

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。

三、典型应用场景

SRP7028A-220M主要适配对可靠性要求高的功率电路,核心场景包括:

  1. 车载电源系统:车载DC-DC转换器(降压/升压)、车载充电器(OBC)的滤波电感,实现电源转换与纹波抑制;
  2. 汽车控制单元(ECU):ECU内部电源电路、传感器信号处理电路的储能/滤波元件,保障控制信号稳定;
  3. 车载照明:LED前照灯、氛围灯驱动电路的电感,满足宽温、抗振动需求;
  4. 工业/通信电源:对可靠性要求较高的工业电源模块、通信设备电源(100KHz频段)的滤波电感。

四、可靠性与品牌支持

1. 车规级可靠性保障

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。

2. BOURNS品牌优势

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。

五、封装适配性

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。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
