BOURNS SM-LP-5001E 产品概述

一、产品简介

BOURNS SM-LP-5001E 属于 SM-LP 系列的局域网用变压器(LAN Transformer),为表面贴装型网络磁性元件。该器件提供信号隔离与阻抗匹配功能,常用于以太网物理层接口,用以提高共模抑制、降低串扰并满足隔离规范。器件状态有源,适合卷带(TR)自动贴装生产。

二、主要规格与参数

  • 制造商:Bourns Inc.
  • 型号:SM-LP-5001E(基本编号 SM-LP)
  • 功能:LAN Transformer(网络变压器)
  • 阻抗/标称:600 Ω
  • 变比:1:1(单通道变比)
  • 电感:3.8 H(标注值)
  • 封装/引脚:SMD-6P(6 引脚)
  • 外型尺寸:9.00 mm × 12.80 mm(0.354" × 0.504")
  • 最大安装高度:7.50 mm(0.295")
  • 安装方式:表面贴装(SMD)
  • 包装:卷带(Tape & Reel)

(以上参数为概要,具体电气特性如插损、回波损耗、共模阻抗及频率响应请参阅原厂数据手册。)

三、典型应用

  • 以太网接口模块(10/100Base-T及兼容应用)
  • 局域网物理层(PHY)前端隔离与匹配
  • 网络设备、交换机、路由器、网卡与工业以太网终端
  • 需要信号隔离、共模噪声抑制及阻抗变换的通信电路

四、尺寸与封装说明

SM-LP-5001E 采用紧凑 SMD-6P 封装,长宽 12.8 mm × 9.0 mm,适合空间受限但需一定通风和绝缘间隙的板上布局。最大安装高度 7.5 mm,适用于常见的自动化贴片流程。卷带包装便于批量 SMT 生产线直接上料。

五、选型与使用建议

  • 布局:建议将变压器靠近 RJ45 或 PHY 芯片放置,TX/RX 信号线尽量短且成对布线,减少不必要的串扰。
  • 接地与屏蔽:合理设计共模接地与磁环屏蔽,依据系统接地策略选择是否接壳向地。
  • 直流偏置与饱和:在有直流通流的场合(如 PoE)需确认器件允许的 DC 通过量,防止磁芯饱和。
  • 焊接工艺:遵循 Bourns 推荐的回流温度曲线和焊膏工艺,避免过热或长时间高温造成性能退化。
  • 验证:在最终产品中应对插损、回波损耗、共模抑制和隔离电压等关键指标进行验证,确保满足系统标准。

如需在特定频率、直流偏置或工业环境中使用,建议获取并参照官方数据手册与应用笔记,或与供应商技术支持确认详细参数与可靠性信息。

六、总结

SM-LP-5001E 是一款面向局域网物理层的紧凑型 SMD 变压器,具有 600 Ω 阻抗和 1:1 变比,适合用于以太网接口的信号隔离与阻抗匹配。其小型化封装与卷带包装使其便于自动化生产,在高可靠性网络设备中具有良好适用性。

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
