SRN6045TA-3R3Y 产品概述

一、产品简介

SRN6045TA-3R3Y 是 BOURNS 推出的表面贴装功率电感,额定电感值 3.3 µH(公差 ±30%),额定电流 5A,饱和电流(Isat)7.8A,直流电阻(DCR)约 21 mΩ。器件符合车规 AEC-Q200 要求,采用 SMD 封装,外形约 6×6 mm,适用于对电流能力和可靠性有较高要求的电源应用。

二、主要规格一览

  • 电感值:3.3 µH ±30%
  • 额定电流:5 A(连续)
  • 饱和电流:7.8 A(Isat,定义为在该电流下电感值降至额定值的一定比例)
  • 直流电阻:21 mΩ(典型/最大值视制造批次而定)
  • 封装:SMD,外形约 6×6 mm
  • 车规等级:AEC-Q200

三、性能与优势

  • 高电流能力:5 A 连续额定,7.8 A 饱和裕度,适合中大电流 DC-DC 降压、负载供电场景。
  • 低 DCR:21 mΩ 带来较低的 I²R 损耗,有利于降低温升与提高效率。
  • 车规级可靠性:满足汽车电子严苛环境(温度、振动)要求,适用于车载电源模块。
  • 紧凑封装:6×6 mm SMD 便于高密度布局与自动化贴装。

四、典型应用

  • 汽车级 DC-DC 降压转换器、车载娱乐与信息系统电源。
  • 工业与通信电源模块、点火控制与传感器供电。
  • 充电与电机驱动辅助电源(作为滤波/储能元件)。

五、设计与使用建议

  • 额定电流为持续工作上限,建议设计时按 80% 左右进行电流降额以保证长期可靠性与温升余量。
  • 计算铜损时按 P = I² × DCR,考虑峰值与纹波电流对损耗的影响,并评估温升。
  • 注意直流偏置效应:实际工作电流会造成电感值下降,尤其接近饱和区时应留裕量。
  • PCB 布局:开关节点走短线、输入/输出电容靠近电感两端,地平面完整并考虑过孔散热。
  • 焊接:遵循元件供方推荐的回流焊工艺曲线,避免过热或长时间高温。

六、可靠性与注意事项

  • 在高温、高纹波电流或连续大电流场景下,应进行温升与寿命验证。
  • 对于要求更低纹波或更高电流的应用,可并联多个电感或选择更低 DCR /更大 Isat 型号。
  • 采购时确认批次资料与电气参数的典型/最大值,必要时索取详细数据手册与样品测试。

七、采购与支持

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
