BOURNS PT61017PEL 网口变压器产品概述

一、产品定位与核心特性

BOURNS PT61017PEL是一款专为10/100 Base-T百兆以太网设计的表面贴装(SMD)网口变压器,由全球老牌电子元件厂商BOURNS出品。作为以太网接口的核心信号转换元件,该变压器通过精准绕组设计与参数匹配,实现信号传输中的阻抗匹配、共模噪声抑制及电平适配,核心特性包括:1CT:1CT中心抽头匝数比、350μH绕组电感、0℃~+70℃工作温度范围,以及12.8×6.9mm紧凑型SMD封装,适配绝大多数常规应用场景的电子设备网口设计。

二、关键技术参数解析

1. 匝数比与绕组结构

PT61017PEL采用1CT:1CT匝数比设计,输入/输出绕组均带中心抽头(CT)。中心抽头的核心作用:

  • 为以太网差分信号提供共模噪声抑制外接端(通常通过电阻/电容接地),减少电磁干扰对信号的影响;
  • 1:1匝数比保证信号幅度无失真,完全适配10/100 Base-T标准的差分信号电平(2.5Vp-p以内)。

2. 传输速率与标准适配

明确支持10/100 Base-T速率,符合IEEE 802.3u百兆以太网标准。绕组高频特性优化后,可在10Mbps(10Base-T)与100Mbps(100Base-TX)下稳定传输,无明显衰减或相位失真,满足家庭、办公及常规工业场景的百兆通信需求。

3. 电感值与阻抗匹配

绕组电感为350μH,是实现以太网传输线阻抗匹配的关键:以太网传输线差分阻抗通常为100Ω,350μH电感与分布电容配合,可抑制信号反射,保证百兆以太网典型传输距离(100米),降低误码率。

4. 工作温度范围

覆盖0℃~+70℃,适配绝大多数室内场景(如家庭路由器、办公室交换机、常规工业设备),平衡了性能与成本,适合常规批量应用(极端温环境需选宽温型号)。

三、封装与物理特性

PT61017PEL采用SMD表面贴装封装,尺寸为12.8mm×6.9mm(长×宽),具有以下优势:

  • 适配SMT自动化贴装,无需人工插件,提高生产效率;
  • 小型化设计节省PCB空间,适合迷你路由器、便携式网络摄像头等紧凑型设备;
  • 引脚布局符合主流RJ45连接器规范,可直接配合使用。

四、典型应用场景

1. 消费电子领域

  • 家用路由器、交换机的百兆LAN/WAN口;
  • 机顶盒、智能电视的网络接口;
  • 便携式WiFi设备的百兆以太网扩展口。

2. 工业与安防领域

  • 小型PLC、工业网关的百兆以太网接口;
  • 网络摄像头、NVR的百兆传输口;
  • 门禁系统、环境监测设备的网络通信模块。

3. 通信终端领域

  • ADSL调制解调器、光纤猫的百兆LAN口;
  • 小型基站、无线AP的百兆以太网接口。

五、应用优势与价值

1. 信号传输稳定

350μH电感与1CT:1CT绕组实现精准阻抗匹配,减少反射与衰减,保证百兆通信低误码率,提升设备可靠性。

2. 抗干扰能力强

中心抽头可外接共模抑制元件,有效抑制电源线噪声、电磁辐射,适合复杂电磁环境(如工业车间、多设备办公区)。

3. 生产与成本优势

SMD封装适配自动化生产,降低人工成本;紧凑型尺寸节省PCB面积,减少设备体积,适合小型化产品设计。

4. 品牌可靠性

BOURNS生产工艺成熟,参数一致性好,批量供货稳定,降低研发与生产中的良率风险。

该产品凭借平衡的性能、成本与可靠性,成为常规百兆以太网设备网口设计的主流选择。

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
