HR051067 电源变压器 产品概述
一、产品简介
HR051067 是汉仁（HANRUN）推出的一款 SMD 封装功率变压器，专为小功率隔离开关电源与 DC-DC 转换器设计。器件为 8 引脚表面贴装型，额定输出功率约 7W，适用于 36–72V 输入范围的隔离型电源解决方案，具有高隔离电压与较低漏感，便于在紧凑电路板上实现稳健的电源拓扑。
二、主要参数
- 匝数比：1 : 0.667 : 0.262
- 初级电压（适配范围）：36 ~ 72 V
- 次级电压：5 V
- 输出电流：1.4 A（次级）
- 一次绕组：双路（可并联/串联以适配不同输入）
- 二次绕组：单路
- 隔离电压（Vrms）：1.5 kV
- 漏感（典型）：3.6 μH
- 封装：SMD，8PIN，功率等级约 7W
- 品牌：HANRUN（汉仁）
三、结构与封装特点
HR051067 采用表面贴装封装，体积小、可回流焊工艺兼容，便于自动化装配。双一次绕组设计增加了输入适配灵活性：对于较高电压输入可将两次级串联/并联方式切换（具体接法请参照生产商原理图），满足不同系统的输入需求。
四、典型应用场景
- 工业或通信领域的隔离式 DC-DC 电源（48V 档位电源尤为合适）
- PoE、基站供电模块的小功率隔离前端
- 嵌入式系统或便携设备的绝缘电源供给
- 各类开关电源参考设计及评估板
五、设计与 PCB 布局建议
- 初级与次级之间保持足够爬电距离并使用专用隔离圈或开槽，以保证 1.5 kV 隔离性能。
- 将变压器与开关器件靠近放置，缩短信号回路面积以降低 EMI。
- 次级走线应尽量粗短，使用适当的铜箔厚度以减小压降和发热。
- 鉴于 3.6 μH 漏感，设计时须考虑吸收/箝位回路（RCD、TVS 或有源钳位）以限制尖峰电压。
- 在大电流输出端加固焊盘与散热通道，必要时在元件下方或周边设计热过孔导出热量。
六、热管理与可靠性
在 1.4A 输出下，变压器会产生一定损耗，建议在设计时进行容量留余并采用良好散热措施（靠近散热片、使用铜箔加厚或多层板散热通孔）。长期可靠性取决于工作温度与焊接工艺，严禁超出制造商的温度与电压极限。
七、选型要点与注意事项
- 确认工作输入电压与一次绕组连接方式（并联或串联）匹配；错误连接可能导致饱和或过压。
- 根据系统开关频率评估漏感对能量回收与 EMI 的影响，并配置合适的吸收或钳位电路。
- 若需更高隔离等级或更大功率，应与供应商沟通对应型号或定制方案。
HR051067 适合在对体积、成本和隔离性能有平衡要求的小功率隔离电源设计中使用。购买与最终设计使用前，建议参照厂方完整数据手册核对引脚定义、焊接工艺与环境规范。

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.
