HR682430E 产品概述
一、产品简介
HR682430E 为 HANRUN（汉仁）出品的网口脉冲变压器系列器件，采用 SMD 表面贴装封装（24 引脚），外形尺寸 15.1×7.1mm。该器件面向以太网物理层磁性组件设计，支持 10/100/1000Base‑T 速率，集成磁性与共模抑制功能，适用于工业级与消费级网口接口模块。
二、主要性能参数
- 支持速率：10/100/1000Base‑T（千兆以太网兼容）
- 电感值：350 µH（用于共模抑制）
- 隔离电压：1.5 kVrms（提供隔离与安全保护）
- 工作温度：-40 ℃ ~ +85 ℃（工业级温度范围）
- 封装与引脚：SMD‑24P，外形 15.1×7.1 mm
以上参数表明本器件在保证网络信号完整性同时，具备良好的抗干扰与隔离能力。
三、典型应用场景
- 以太网 PHY 芯片与 RJ45 插座之间的磁性组件（网口变压器）
- 工业以太网、交换机、路由器、PoE 供电模块的信号隔离与共模噪声抑制
- 嵌入式设备、网关与监控设备的网络接口保护与滤波
四、性能优势
- 支持千兆速率，保证高速差分信号传输与阻抗一致性，降低串扰与反射
- 350 µH 的共模电感有效抑制地线环路与 EMI，提升系统抗干扰能力
- 1.5 kVrms 隔离等级为设备间静电与瞬态提供保护，符合常见安全与可靠性要求
- 宽温工作范围，适应严苛工业环境与长期运行需求
五、PCB 布局与焊接建议
- 尽量将 HR682430E 放置于 PHY 芯片与 RJ45 插座之间，差分对走线短且对称，保持阻抗匹配（通常 100 Ω 差分）
- 共模磁芯与接地平面配合使用，减少地回路与辐射；信号地与保护地根据系统要求分开处理并在合适点连接
- SMD 焊接推荐遵循元件供应商提供的回流温度曲线，避免过热导致磁性材料退磁或封装变形
- 在布局时为隔离通道留足距离，避免高压与低压侧走线交叉
六、可靠性与注意事项
- 长期在高温或高湿环境下使用应评估绝缘老化与磁芯性能变化，必要时进行加速寿命试验验证
- 避免在高能脉冲干扰源附近直接放置，以免引发瞬态过电压穿透隔离层
- 采购时确认批次一致性与相关 RoHS、REACH 等环保合规文件
七、选型与采购建议
在选型时，确认所需网络速率、隔离等级与工作温度范围是否满足系统需求；若系统需要 PoE 功能或更高隔离/传导抑制能力，可与供应商沟通是否有带中心抽头、不同电感或更高 Vrms 等变型产品。建议向 HANRUN 或授权渠道采购，并索取完整数据手册、封装图和推荐焊接工艺文件以便于可靠应用。

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.
