HR641640E是汉仁(HANRUN)推出的SMD封装单口以太网变压器模块,专为10/100Base-T以太网接口设计,核心作用是实现网络信号的电磁隔离、电压隔离与信号耦合,解决数据传输中的共模干扰、浪涌防护问题,同时保障信号传输完整性。作为以太网PHY芯片与网络接口之间的关键组件,该模块兼顾小体积、高可靠性与宽温适应性,适配多类终端设备的生产与应用需求。
该模块的关键参数针对以太网通信实际需求优化,各参数的核心意义如下:
采用单口设计,支持10/100Base-T自适应速率(10Mbps/100Mbps),覆盖低速以太网(如家庭网关)到快速以太网(如小型工业交换机)的主流场景,无需额外切换电路即可适配不同速率网络环境。
电感值为350uH,是10/100Base-T接口的典型优化值:既保证信号耦合效率(减少传输损耗),又避免过高电感导致的带宽限制,确保100Mbps速率下的数据传输完整性。
具备1.5kVrms隔离电压,符合IEC关于以太网隔离的基本要求,可有效隔离网络侧与设备侧的共模干扰(如电网浪涌、电磁辐射),保护后端敏感电路(如PHY芯片、MCU)免受损坏。
支持**-40℃+85℃工业级温宽**,远超普通商业级模块(0℃70℃),可稳定应用于户外设备(如智能路灯网关)、工业车间(如PLC控制器)等温差较大场景。
采用SMD(表面贴装)封装,体积紧凑,适配自动化贴片生产线,显著节省PCB空间(尤其适合小体积终端设备),且兼容回流焊工艺,降低生产难度与成本。
汉仁在HR641640E设计中重点强化可靠性,核心亮点包括:
HR641640E参数特性使其适配多类终端设备,典型应用包括:
为确保稳定工作,需注意以下几点:
HR641640E作为汉仁高性价比单口以太网变压器,以工业级宽温、1.5kV高隔离、SMD小体积为核心优势,覆盖10/100Base-T主流场景,适配工业、消费电子、物联网等领域需求。可靠设计与品牌保障,使其成为终端设备的理想选择。
Request for quote
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.
