SRN3015TA-2R2M 产品概述

一、主要参数

SRN3015TA-2R2M 是 BOURNS 的表贴功率电感,针对车用与工业电源应用优化。主要电气参数如下:

  • 标称电感值:2.2 µH(公差 ±20%)
  • 额定电流:1.7 A
  • 饱和电流(Isat):1.7 A
  • 直流电阻(DCR):约 60 mΩ
  • 封装形式:SMD,封装尺寸 3.0 × 3.0 mm
  • 车规等级:符合 AEC‑Q200 可靠性要求

二、产品特性

  • 小型化设计:3×3 mm 的紧凑封装适合高密度 PCB 布局,适用于点位负载(Point‑of‑Load)和板级 DC‑DC 转换器。
  • 高可靠性:通过 AEC‑Q200 认证,适合汽车电子(例如车身电子、信息娱乐、ADAS 辅助电源)以及苛刻工业环境。
  • 性能平衡:2.2 µH 与 1.7 A 的组合可提供稳定的储能能力,同时 DCR 在 60 mΩ 范围内,兼顾损耗与体积。
  • 磁芯与屏蔽:采用高性能铁氧体磁芯(制造商资料标注),具备良好磁通密度和低漏磁特性(具体详见原厂数据表)。

三、典型应用

  • 降压(Buck)开关电源中的输出电感(PoL converters)
  • 电源管理模块(PMIC)和点位供电
  • 汽车车载电子(车身控制单元、仪表、信息娱乐)
  • 工业控制与嵌入式供电模块

四、使用与布局建议

  • 电流与饱和裕量:饱和电流 Isat 与额定电流相同(1.7 A),表明在接近额定电流时电感可能出现较显著的饱和效应。建议在持续负载场合采取电流降额(典型降额至 70–80%),以保证线性区与温升裕量。
  • 损耗估算:仅考虑 DCR 的铜损约为 P ≈ I^2·DCR,满载 1.7 A 时约为 0.17 W(仅欧姆损耗,不含磁芯损耗),请结合开关频率评估总体温升与效率。
  • PCB 布局:将电感尽量靠近开关器件与输出电容,减小环路面积以降低 EMI;输入/输出电容应靠近电感两端;对大电流路径使用多孔过孔或加粗走线以降低寄生阻抗和热阻。
  • 回流与焊接:遵循厂家推荐的焊盘设计与回流曲线,避免过长的预热或超温导致磁性材料性能退化。

五、可靠性与车规说明

SRN3015TA‑2R2M 已按 AEC‑Q200 要求设计与测试,具备汽车级温度循环、机械振动和高温储存等可靠性验证。实际设计中还应关注工作温度对电感值与 DCR 的影响,必要时参考 BOURNS 的完整数据手册获取温度特性与寿命评估数据。

六、选型与替代建议

  • 若需更高电流承载能力或更低 DCR,可考虑更大封装或同系列高电流型号;若需更严格电感偏差,请选择更高精度(±10%、±5%)的器件系列。
  • 在关键车规或高温场合,建议与供应商确认实际温升测试结果与长期老化数据,进行必要的电流降额与热仿真验证。

如需更详细的电感曲线(频率响应、磁芯损耗、Id‑Ldrop 曲线)、建议封装 Land‑pattern 或环境测试报告,可提供具体的设计要求,我可帮您查找并整理原厂数据表中的关键图表与数值。

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
