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。
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:
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。
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。
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)。
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:
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。
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)。
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。
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。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
