BOURNS SRP1265A-330M屏蔽绕线电感器产品概述

BOURNS SRP1265A-330M是一款专为高电流、高可靠性场景打造的屏蔽绕线功率电感,凭借车规级AEC-Q200认证、低直流电阻(DCR)及合理的电流参数,成为车载电子、工业电源等领域的优选组件。

一、产品核心定位与应用方向

该电感属于功率电感范畴,核心定位为高电流密度、低EMI干扰的车规级绕线电感,重点覆盖以下应用方向:

  • 车载电子系统:车载DC-DC转换器、LED驱动电源、ADAS辅助驾驶模块;
  • 工业电源设备:服务器电源、通信基站电源、光伏逆变器;
  • 高功率消费电子:快充适配器、大功率LED照明驱动。

其屏蔽设计可有效抑制电磁干扰,适配对EMI敏感的场景,同时车规认证确保极端环境下的稳定运行。

二、关键电气性能参数详解

1. 电感与精度

电感值为33μH±20%,该精度范围满足大多数功率电路的设计需求(无需高精度电感的场景),兼顾成本与性能平衡。

2. 电流参数

  • 额定电流(Irms):8A:连续工作电流上限,此电流下电感温升控制在行业标准范围内(通常≤40K),可长期稳定运行;
  • 饱和电流(Isat):11A:电感值下降30%时的峰值电流,比额定电流高37.5%,为电路中的瞬态峰值电流(如负载突变)预留充足余量,避免电感饱和导致的性能下降。

3. 直流电阻(DCR)

最大直流电阻为58mΩ,属于低DCR设计——低DCR意味着电流通过时的功率损耗(I²R)更低,可有效降低电感自身发热,提升系统效率,尤其适合大电流应用场景。

4. 屏蔽设计

采用屏蔽绕线结构(通常为铁氧体磁芯包裹绕线),大幅减少漏磁,降低对周边电路的电磁干扰(EMI),符合汽车电子、通信设备对EMI的严格要求。

三、物理封装与可靠性设计

1. 封装规格

为表面贴装(SMD)封装,实际尺寸为13.5mm×12.5mm(对应封装代号1265,行业通常以宽度×高度简化命名),适配自动化贴片生产线,焊接兼容性强。

2. 材料与结构

  • 磁芯采用耐高温铁氧体材料,适配宽温环境;
  • 绕线使用高导电率漆包线,确保低DCR的同时具备良好的耐温性;
  • 屏蔽结构通过磁芯包裹绕线,减少漏磁的同时提升机械稳定性。

四、车规级认证与环境适应性

1. AEC-Q200认证

该产品通过汽车电子元器件可靠性标准AEC-Q200,涵盖以下严苛测试:

  • 温度循环:-40℃至+125℃(典型车规温度范围)的循环测试;
  • 振动与冲击:承受汽车行驶中的高频振动(10-2000Hz)及冲击(100G以上);
  • 湿度与老化:高湿环境下的长期可靠性测试。

2. 环境适应性

可稳定工作于**-40℃至+125℃**的宽温度范围,满足车载、工业等场景的极端温度需求,无性能衰减或失效风险。

五、应用场景案例解析

1. 车载DC-DC转换器

车载12V/24V系统向低电压(如5V、3.3V)转换时,SRP1265A-330M可作为储能电感:

  • 8A额定电流满足多设备供电需求;
  • 58mΩ低DCR减少电源损耗,提升转换效率;
  • 屏蔽设计避免对车载通信系统的EMI干扰。

2. 工业服务器电源

服务器电源需要高电流、高可靠性,该电感:

  • 11A饱和电流应对瞬态负载突变;
  • 车规级可靠性确保7×24小时连续运行;
  • 小尺寸封装适配服务器高密度PCB设计。

总结:BOURNS SRP1265A-330M以车规级可靠性、低EMI、高电流密度为核心优势,精准匹配车载电子、工业电源等对性能与可靠性要求严苛的场景,是一款高性价比的功率电感解决方案。

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
