HR644001E 网口脉冲变压器产品概述
一、产品定位与典型应用
HR644001E是汉仁（HANRUN）推出的10/100Base-T以太网专用脉冲变压器，核心作用是实现以太网信号的隔离传输、阻抗匹配及抗干扰，是工业、消费电子等领域以太网接口的关键器件。其典型应用场景包括：
- 工业级设备：PLC（可编程逻辑控制器）、工业交换机、智能网关、物联网终端；
- 消费电子：家用路由器、百兆交换机、机顶盒、安防监控主机；
- 嵌入式系统：车载以太网模块、小型通信设备。
二、关键技术参数解析
该产品参数围绕以太网信号可靠性与安全性设计，核心指标及意义如下：
- 传输速率：10/100 Base-T兼容
支持百兆以太网（100Mbps）及10Mbps以太网，覆盖主流中低速带宽需求，适配大多数终端设备的网口传输要求； - 电感值：350uH
电感值是脉冲变压器的核心性能指标，350uH可精准匹配以太网PHY芯片与双绞线的阻抗，减少信号反射与损耗，保障信号完整性； - 隔离电压：1.5kV（Vrms）
1.5kV交流隔离电压（有效值）满足电气安全规范，可有效隔离设备内部电路与外部网络的干扰（如雷击、浪涌），避免芯片损坏； - 工作温度：-40℃~+85℃
宽温范围覆盖工业级环境要求，可稳定工作于低温严寒、高温湿热场景，无需额外散热/保温设计。
三、封装与物理特性
HR644001E采用表面贴装（SMD）封装，具体参数：
- 封装类型：SMD-20P（产品描述中提及SMD-40P，建议以汉仁官方规格书为准）；
- 尺寸：28mm×11.9mm，紧凑设计节省PCB空间，适合小型化设备；
- 贴装优势：表面贴装适配自动化生产，提高贴片效率，降低人工成本。
四、品牌与可靠性优势
汉仁作为国内专业网口器件厂商，HR644001E继承了品牌可靠性：
- 磁芯材料：采用高稳定性锰锌铁氧体，电感值一致性好，批量生产性能波动小；
- 工艺控制：严格遵循RoHS环保规范，生产过程经过多轮EMC测试，抗干扰能力强；
- 测试验证：通过工业级环境可靠性测试（高低温循环、振动冲击），适配恶劣工况。
五、应用注意事项
- PCB布局：缩短变压器与PHY芯片的走线距离，避免信号串扰；
- 焊接要求：采用回流焊工艺，焊接温度需符合汉仁推荐曲线（峰值230℃~250℃，时间≤30s）；
- 存储条件：未使用时存放于干燥通风环境（湿度≤60%RH，温度15℃~35℃），避免静电损伤；
- 规格确认：使用前核对官方规格书，确认引脚定义与应用场景匹配。
HR644001E凭借宽温范围、高隔离电压及紧凑封装，成为工业与消费电子领域以太网接口的高性价比选择，可满足多数中低速以太网设备的核心传输需求。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
