HR681616 产品概述
一、产品简介
HR681616 为 HANRUN（汉仁）出品的一款 SMD 封装网络磁性元件，适配 10/100 Base‑T 以太网接口。器件采用对称绕组设计（匝数比 1CT:1CT），在保持差模信号传输的同时提供必要的共模抑制与隔离保护。典型应用为 RJ45 插座与以太网收发器（PHY）之间的耦合与保护。
二、主要参数与特点
- 匝数比：1CT:1CT（双对称绕组，带中点抽头），便于差分与共模处理。
- 工作速率：支持 10/100 Base‑T，以太网物理层常见速率。
- 电感值：120 μH（表征共模/磁通特性，对低频噪声抑制有效）。
- 隔离电压：1.5 kV Vrms（绝缘与安全隔离用途）。
- 封装：SMD，便于自动贴装与回流焊工艺。
这些特性使 HR681616 在常规工业与商用以太网端口中具备良好的电磁兼容与安全隔离能力。
三、典型应用场景
- 10/100 Base‑T 以太网端口磁耦合/共模抑制器件；
- 嵌入式网络设备（路由器、交换机、网关）与模块接口；
- 工业以太网前端接口，需一定隔离电压和抗干扰能力的场合；
- 对体积、自动化贴装有要求的消费电子与通信设备。
四、封装与布局建议
- SMD 形式便于靠近 RJ45 座或 PHY 布局，建议将器件放置在物理接口与 PHY 之间以缩短信号走线；
- 中点抽头（CT）根据系统需要接入偏置（如连接到供电或接地）时，注意遵循 PHY / 系统设计说明；
- PCB 布线注意差分对对称性、最小化回流回路面积，避免穿过敏感模拟电路区；
- 回流焊温度曲线按厂家推荐，避免过高峰值温度对磁芯与绝缘材料造成损害。
五、可靠性与测试要点
在设计验证中建议关注以下测试项目：耐压（Hi‑Pot）、绝缘电阻、直流电阻（DCR）、磁化电流、插入损耗与回波损耗（S 参数）、共模抑制比（CMRR）以及在温度循环与潮湿条件下的长期稳定性测试。隔离等级 1.5 kV Vrms 在某些更严格的工业/安规场合可能需额外评估。
六、选型与替代注意事项
选型时除上述标称参数外，还应确认：最大工作电流、在目标频段的频率响应、插入损耗与回波损耗指标、以及是否满足系统所需的安规标准（如 IEC/EN 要求）。如需更高隔离或更高频段性能，可选用同类厂商更高规格或其他型号替代。若需进一步匹配 PoE 应用，应核实电流承载能力与温升特性。
如需更详细的电气特性曲线、封装图与推荐焊盘，请提供是否需要查询官方 Datasheet 或样片评估，我可继续协助。

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.
