HR682480E 产品概述
一、产品简介
HR682480E 为 HANRUN（汉仁）出品的一款网口/脉冲变压器（X-FMR-24P），封装为 SMD-24P，外形尺寸 15.1 x 7.1 mm。该器件面向 100/1000 Base-T 以太网接口，集成脉冲变压、隔离及共模抑制功能，适用于中高密度网口模块和工业级网络设备。
二、主要性能参数
- 速率：100/1000 Base-T，支持千兆以太网链路传输要求；
- 电感值：350 μH（标称），用于增强共模抑制与抑制电磁干扰（EMI）；
- 隔离电压：1.5 kV rms，提供端口与系统地之间的安全隔离；
- 工作温度：-40 ℃ ~ +85 ℃，满足工业级工作环境；
- 封装：SMD-24P（15.1 x 7.1 mm），便于表面贴装与自动化装配。
三、功能与应用场景
该变压器用于以太网物理层（PHY）与隔离端口之间的电气隔离与阻抗匹配，主要功能包括：差分信号耦合、脉冲整形、共模噪声抑制以及提供安全隔离。典型应用场景有：交换机、路由器、千兆网卡、工业以太网设备、IP 摄像头、网关与嵌入式网络模块等。
四、设计与使用建议
- PCB 布局：建议将变压器放置靠近 RJ45 插座与 PHY 芯片之间，缩短信号走线，保持差分线路对称并控制线长差异；
- 接地与隔离：保留变压器两侧各自的地平面，避免打穿隔离槽；若系统需更高安全等级，可在设计中增加隔离与防护电路；
- 焊接工艺：适用于标准回流焊流程，建议遵循元器件供应商的焊接温度曲线以保证焊点可靠性；
- EMI 控制：结合 350 μH 的共模电感特性，可通过合理放置磁环或 EMI 滤波器进一步降低干扰。
五、可靠性与环境适应性
HR682480E 工作温度范围 -40 ℃ 到 +85 ℃，适应室温与工业环境的温湿度变化。隔离电压 1.5 kV rms 提供基础的安全防护；在高电磁干扰场合应结合外部防护措施（如 TVS、滤波网络）提升系统抗扰度与稳健性。
六、采购与封装信息
- 品牌：HANRUN（汉仁）；型号：HR682480E；
- 封装形式：SMD-24P，尺寸 15.1 x 7.1 mm，适合自动贴装与批量生产；
- 建议在订单与工程样片阶段确认器件的完整数据手册（包括引脚排列、等效电路及最大额定值），并与供应商沟通可获的放样或长期供货能力。
总结：HR682480E 在保证千兆以太网性能的同时，兼顾工业级温度与隔离要求，适合对体积、性能与可靠性有综合考量的网络设备设计。选型时请结合具体系统的电气规范与安全需求，确认隔离等级与 EMC 方案的匹配。

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.
