BOURNS SRP1038A-150M 功率电感产品概述

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。

一、产品定位与核心设计目标

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:

  1. 满足汽车电子环境的高可靠性要求(通过AEC-Q200认证);
  2. 兼顾持续工作电流与峰值耐受能力(额定电流6.25A、饱和电流10A);
  3. 小体积适配车载设备小型化趋势(10×11mm SMD封装)。

二、关键电气性能参数解析

1. 电感特性

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。

2. 电流承载能力

  • 额定电流(Irms)6.25A:指电感在25℃环境下持续工作时,电感值变化不超过10%、温度不超过额定值的最大电流,是电路持续工作的安全上限;
  • 饱和电流(Isat)10A:指电感值下降30%时的峰值电流,可应对设备启动、负载突变等场景下的瞬间大电流,避免电感性能失效。

3. 损耗特性

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。

三、机械与封装特性

1. 封装与尺寸

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。

2. 结构设计

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。

四、典型应用场景

SRP1038A-150M的性能参数与车规认证使其在以下场景中表现优异:

  1. 车载电子电源系统:12V/24V车载DC-DC转换器(如车机、ADAS模块电源)、LED车灯驱动电路;
  2. 汽车电机驱动:座椅调节、车窗升降、后视镜折叠等小功率电机的驱动电路(峰值电流耐受能力适配电机启动瞬间电流);
  3. 工业与消费电子:工业电源模块、智能家居设备的中功率电源电路(非车规场景中也可满足高可靠性需求)。

五、可靠性与认证

1. 车规级认证

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。

2. 环保与合规

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。

六、选型与使用注意事项

  1. 电流限制:电路持续工作电流需低于6.25A,峰值电流需低于10A,避免电感饱和或过热;
  2. 散热设计:PCB布局需预留足够散热空间,避免电感与发热元件过近,必要时可通过敷铜增强散热;
  3. 布线要求:电感引脚布线需尽量短,避免引入额外寄生参数;敏感电路(如射频)需与电感保持一定距离,减少电磁干扰;
  4. 焊接工艺:需符合贴片元件的回流焊规范,避免虚焊、假焊导致的性能失效。

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。

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
