BOURNS SRP2512TMA-R47M 功率电感产品概述

一、核心参数总览

BOURNS SRP2512TMA-R47M是一款专为高电流、高密度应用设计的屏蔽式绕线功率电感,核心参数清晰明确:

  • 电感值:标称470nH(0.47μH),精度±20%;
  • 电流能力:额定电流(Irms)6.2A,饱和电流(Isat)6.2A(两者一致,磁饱和特性优异);
  • 直流电阻(DCR):典型值15mΩ,部分测试条件下可达约0.018Ω,低电阻降低直流功耗;
  • 频率特性:1MHz工作频率下Q因子15,交流损耗低;
  • 封装:2512公制表面贴装(对应英制1008),尺寸紧凑(约2.5mm×2.0mm×1.2mm)。

二、封装与结构设计

该电感采用屏蔽式绕线结构,核心优势在于:

  1. 电磁兼容性(EMC):屏蔽层有效抑制电感对外的电磁辐射,同时减少外部干扰对自身性能的影响,适合对EMI敏感的车载、通信设备;
  2. 小体积高集成:2512封装仅为指甲盖大小,可适配高密度PCB布局,解决消费电子、汽车电子的空间限制问题;
  3. 绕线工艺:采用高精度绕线技术,确保电感值一致性,减少批量生产中的性能波动。

三、关键性能特性

3.1 高电流稳定性

饱和电流(Isat)与额定电流(Irms)均为6.2A,意味着电感在额定工作电流下不会因磁芯饱和导致电感值骤降,可稳定输出高电流,适合DC-DC转换器等大电流场景。低DCR(15mΩ)进一步降低了铜损,减少设备发热,提升系统效率。

3.2 高频低损耗

1MHz下Q因子达15,表明电感的交流损耗(磁损+铜损) 控制在较低水平,能量转换效率高。这一特性使其适配高频开关电源(如快充、服务器电源),可有效降低电源模块的发热,延长设备寿命。

3.3 汽车级可靠性

产品通过AEC-Q200汽车电子可靠性认证,可承受以下严苛环境:

  • 温度范围:-40℃至+125℃(覆盖车载极端工况);
  • 机械应力:抗振动(典型10G)、抗冲击(典型50G);
  • 环境适应性:耐湿度、耐盐雾,满足车载系统长期稳定运行需求。

四、典型应用场景

SRP2512TMA-R47M凭借性能与可靠性,广泛覆盖三大领域:

  1. 汽车电子:车载DC-DC转换器(12V转5V/3.3V)、ADAS传感器模块(毫米波雷达、摄像头电源)、车载信息娱乐系统(IVI)、车身控制单元(BCM);
  2. 工业与通信:服务器/数据中心电源、通信基站电源、工业变频器电源、LED驱动电源;
  3. 消费电子:高性能笔记本电脑电源、PD3.0/QC4.0快充充电器、游戏主机电源模块。

五、合规与认证

除AEC-Q200外,该产品还符合:

  • RoHS 2.0:无铅、无镉等有害物质;
  • REACH:满足欧盟化学品注册、评估、授权与限制要求;
  • 符合全球电子设备的环保与安全标准,便于产品全球化部署。

该电感平衡了小体积、高电流、低损耗与可靠性,是车载、工业、消费电子领域高功率密度应用的优选方案。

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
