SRN6045TA-680M 产品概述

一、产品简介

SRN6045TA-680M 为 BOURNS 出品的功率电感,标称电感值 68 μH,公差 ±20%,为表面贴装(SMD)封装(6×6 mm)。该器件为车规等级(AEC‑Q200)元件,适用于对可靠性和环境耐受性有较高要求的汽车及工业电子应用。其额定电流为 1.1 A,饱和电流(Isat)为 1.6 A,直流电阻(DCR)为 305 mΩ,具备良好的电流承载能力和热稳定性,适合用作功率滤波与储能元件。

二、主要性能与特点

  • 电感值:68 μH,适合中低频滤波和能量储存场景。
  • 精度:±20%,符合典型功率电感公差需求。
  • 电流能力:额定电流 1.1 A,饱和电流 1.6 A,可应对短时或脉冲性较大的负载。
  • 低频损耗:DCR 305 mΩ,能量损耗和发热处于可控范围(设计需考虑功耗)。
  • 封装与安装:SMD,6×6 mm,便于自动贴装与高密度 PCB 设计。
  • 车规等级:符合 AEC‑Q200,适合汽车电子和严苛环境使用。

三、典型应用场景

  • 汽车电子:车载控制单元、车身电子、传感器电源滤波与去耦。
  • 工业电源:开关电源输出滤波、降压转换器储能元件。
  • 通讯与消费类设备:需要中等功率滤波或抑制干扰的电源模块。
  • 分立式电源管理:用于抑制纹波和稳定负载供电。

四、选型与设计要点

  • 电流裕量:推荐在额定电流 1.1 A 以下长期使用,若工作中存在大幅脉冲或瞬间峰值,应确保峰值不超过 Isat(1.6 A)以防磁饱和。
  • DC 偏置影响:电感值会随直流偏置电流下降,实际电感需按工作电流下的有效值评估电路性能。
  • 损耗与温升:DCR 为 305 mΩ,通流时会产生功耗 P = I^2·DCR,设计时应计算温升并预留散热与降额空间。
  • 封装匹配:6×6 mm SMD 便于高密度布局,但请确认 PCB 焊盘设计与贴装工艺符合制造能力。

五、PCB 布局与焊接建议

  • 尽量将电感靠近开关器件或负载放置,缩短电流回路,减少寄生电感和噪声。
  • 为降低热阻,必要时在电感焊盘下方或周围布置铜地/散热铺铜,并考虑热过孔以利散热(须与器件供应商确认)。
  • 遵循厂家推荐的焊盘尺寸与回流焊曲线(参考 JEDEC/J‑STD 标准或厂商资料),避免超温或过长湿热暴露导致性能退化。
  • 焊接后进行外观与阻值检查,确保焊点完整、无虚焊。

六、可靠性与测试建议

  • 作为 AEC‑Q200 器件,适用于汽车级可靠性要求,但在最终应用前仍建议做环境应力测试(温度循环、湿热、振动)以及电气测试(直流电阻、感量测试、饱和电流验证)。
  • 测试电感值时注意标注的测试频率与偏置条件,避免因测试条件不同导致的数据偏差。

七、使用注意事项

  • 避免长期在接近或超过额定电流的条件下工作,以防寿命下降或磁芯退磁。
  • 对于脉冲大、纹波强的场合,应评估额外温升与电感衰减后的系统性能。
  • 在高速开关应用中,需注意器件自谐和寄生电容对 EMI 的影响,必要时辅以 RC 或共模滤波等抑制措施。

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
