SRP5030T-100M 产品概述

一、产品简介

SRP5030T-100M 为 BOURNS 出品的一款功率贴片电感,标称电感值 10µH,公差 ±20%。器件尺寸为 SMD 5.7×5.2mm,适合在空间受限的模块化电源和开关电源中作为储能与滤波元件使用。设计用于承受较高直流电流并保持良好磁通不饱和特性,适配中低功率功率转换应用。

二、主要规格

  • 电感值:10µH ±20%
  • 额定电流(Irated):2.75A
  • 饱和电流(Isat):3.5A(L 降至额定值的 25% 或厂方定义条件下)
  • 直流电阻(DCR):约 128mΩ
  • 封装:SMD,尺寸 5.7×5.2mm
  • 品牌:BOURNS

三、性能特点

  • 大电流能力:额定电流 2.75A,可在中等电流负载下长期工作,饱和电流 3.5A,保证短时峰值电流不致严重饱和。
  • 低 DCR:约 128mΩ,降低铜损与功耗,有利于提高转换效率并减小温升。
  • 紧凑封装:5.7×5.2mm 表贴封装,便于自动化贴装与高密度 PCB 布局。
  • 宽泛适用性:适合作为储能与滤波元件在 DC-DC 降压/升压转换器、LED 驱动、电源模块输入输出滤波等场景中使用。

四、典型应用

  • 开关型 DC-DC 降压/升压转换器(同步/非同步)
  • 电源模块的输出储能与输出滤波
  • LED 驱动与背光电源
  • 工业与消费电子中需要中等电流处理能力的电源系统

五、选型与使用建议

  • 工作电流应以额定电流 2.75A 为长期参考,尽量避免在常态下靠近饱和电流 3.5A,以免电感量显著下降影响电路性能。
  • 考虑到温升与效率影响,设计时应留有余量并确认在最大工作温度下的电感与 DCR 性能。
  • PCB 布局上建议将电感靠近开关器件和负载放置,缩短寄生回路,优化散热路径。
  • 参照厂方数据手册评估谐振频率与频率特性,确保护交流纹波与 EMI 满足系统需求。

六、封装与可靠性建议

  • 采用推荐的焊盘、回流工艺及清洁流程以保证焊接可靠性;避免重复受热造成性能变化。
  • 在高温或高湿环境下使用时,应做环境试验验证电感的长期稳定性与热循环耐受性。

该型号结合较高的电流承载能力、紧凑体积与较低 DCR,是中低功率开关电源与模块化电源设计中常用的功率电感选择。若需更详细的频率响应、温升曲线或典型应用电路,请参考 BOURNS 官方数据手册。

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
