SRP1038A-100M — BOURNS 功率电感产品概述

一、概述

SRP1038A-100M 是 BOURNS 针对汽车与高可靠性电源应用推出的一款表面贴装型功率电感。其标称电感值为 10 µH(公差 ±20%),饱和电流(Isat)达 12 A,直流电阻(DCR)约为 30 mΩ,额定工作电流为 7.5 A,并通过 AEC‑Q200 车规级认证。封装为 SMD,外形尺寸约 11 × 10 mm,适合用于空间受限且需高电流能力的稳压与滤波电路。

二、主要参数(摘要)

  • 品牌:BOURNS
  • 型号:SRP1038A-100M
  • 电感值:10 µH ±20%
  • 饱和电流(Isat):12 A(通常指在规定磁通下降限值下的峰值电流)
  • 额定电流:7.5 A(连续允许电流,考虑温升与损耗限制)
  • 直流电阻(DCR):约 30 mΩ(影响铜损与转换效率)
  • 封装:SMD,尺寸约 11 × 10 mm
  • 等级:AEC‑Q200(车规可靠性)

三、特点与优势

  • 高电流能力:12 A 的饱和电流保证在瞬态或峰值条件下保持足够的电感量,适合降压转换器的输出或能承受启动/浪涌电流的场合。
  • 实用的额定电流:7.5 A 的额定连续电流配合较低的 DCR(≈30 mΩ),在中等功率密度设计中能够兼顾效率与热管理。
  • 车规可靠性:通过 AEC‑Q200 认证,适合汽车电子、工业及其它对可靠性要求较高的应用。
  • 紧凑封装:11×10 mm 的 SMD 尺寸适合 PCB 高密度布局,同时便于自动化贴装与回流焊流程。

四、典型应用场景

  • 汽车车载电源(ECU、车用通信模块、仪表)
  • DC‑DC 降压转换器(同步/非同步)输出滤波与能量储存
  • 工业控制电源与点到点电源模块
  • LED 驱动与车用照明电源系统
  • 需要高耐受浪涌电流的电源前端滤波

五、设计与选型建议

  • 区分 Isat 与 额定电流:Isat(12 A)为饱和点参考,短时峰值电流可接近该值而电感降小;长期运行应以 7.5 A 的额定电流为基准以避免过高温升与损耗。
  • 考虑 DCR 对效率的影响:30 mΩ 在高电流下会产生显著 I²R 损耗,需评估系统效率与散热。必要时可通过并联或更低 DCR 元件来优化。
  • 温升与散热:在 PCB 布局时应提供良好的铜箔散热路径与必要的热沉或过孔,减少电感本体温度上升对电感值和寿命的影响。
  • 布局注意事项:将电感尽量靠近开关器件或负载,缩短高电流回路的走线,增设适量电容以抑制开关噪声。
  • 电感公差影响:±20% 的电感公差在滤波与谐振点设计时需留有裕量,必要时通过仿真或样机验证滤波特性。

六、可靠性与封装

作为 AEC‑Q200 车规级元件,SRP1038A-100M 满足汽车环境下的温度循环、机械应力与电气可靠性测试要求。SMD 封装便于自动化生产与回流焊接,但在焊接工艺上仍建议遵循厂方焊接规程,避免过长的高温暴露以保护磁芯与粘结材料。

七、结论

SRP1038A-100M 以其 10 µH 的电感值、高达 12 A 的饱和电流、以及 7.5 A 的连续额定电流,加之 AEC‑Q200 车规认证和紧凑的 SMD 尺寸,适合用于对电流承受能力、可靠性和封装工艺有较高要求的汽车及工业电源设计。在选型时应充分考虑 DCR 对系统效率与散热的影响,并按实际工作电流与温升条件进行适当的余量设计与 PCB 布局优化。若需进一步的典型波形、温升曲线或封装推荐焊盘,请参考 BOURNS 官方规格书或联系供应商获取详尽数据与应用建议。

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
