HR051142 产品概述

一、概况

HR051142 是 HANRUN(汉仁)推出的一款 SMD 封装电源变压器,封装为 10 引脚贴片(SMD_10PIN),额定功率 13W。该器件面向开关电源小功率隔离电源应用,二次端额定输出 12V、1.08A(13W)。典型电气指标包括匝数比 1 : 0.5 : 0.5、一次绕组为双路、二次绕组为单路、隔离电压 1.5kV Vrms、漏感约 1 μH。

二、关键参数说明

  • 匝数比 1:0.5:0.5:表明绕组设计可支持两个相同的次级绕组结构(每组为主绕组一半匝数),在不同版型或连接方式下可按需求实现串/并联或内部并接的配置以满足电压/电流要求。
  • 次级电压与功率:12V、1.08A 对应额定输出功率约 13W,适合为小功率负载或后级稳压电路供电。
  • 一次绕组双路:常用于适配多输入电压(可串联或并联以适配 110/220V),或分流一次侧电流以降低绕组发热。实际连接方式应参照出厂文档或样片确认。
  • 隔离电压 1.5kV Vrms:满足基本的隔离要求,适用于需要隔离保护但不是高压加固型的使用场景。若需更高等级的绝缘或符合特定安规(如医疗、部分工业场合),需确认是否满足该标准或选择更高耐压产品。
  • 漏感 1 μH:较低的漏感有利于减少寄生谐振与电压尖峰,降低电磁干扰(EMI)问题,但仍建议在高开关电压/电流下配合适当箝位和吸收电路。

三、典型应用

  • 开关电源隔离输出部分(小功率 DC-DC、适配器二次侧)
  • 工业控制与仪表的辅助电源
  • 通信设备、机顶盒、智能家居模块的电源模块
  • LED 驱动器、便携式设备电源板(满足 12V 小功率输出)

四、设计与使用建议

  • 初次设计时务必索取完整数据手册与封装尺寸图,确认引脚定义与一次/二次绕组的具体连接方式。
  • 若一次绕组为双路且需跨电压输入,按手册指示进行串/并联连接;不当连接可能导致损坏。
  • 即使漏感较小,仍建议在初级与次级分别设计软启动、电流限制与过压/过流保护;在高 dv/dt 场合加入 RCD(箝位网络)或 TVS 以抑制尖峰。
  • SMD 贴片封装需遵循回流焊工艺规范,避免超温烘烤;为减少机械应力,设计稳固的焊盘与可能的机械支撑(如点胶或夹持)以提高抗振动性能。
  • 热管理:在靠近高温元件或密集布板时考虑热沉或在 PCB 下方加热通孔,必要时对输出做适度降额(建议连续工作在额定功率的 70–80% 可提高寿命)。

五、检验与可靠性验证

  • 进行耐压(HiPot)测试以验证 1.5kV 隔离能力;同时做匝间短路、匝数比和直流电阻测量以确认绕组完整性。
  • 在额定负载及不同环境温度下进行温升试验,记录绕组及磁芯温度,确保满足长期运行稳定性。
  • 做短路/过载保护验证,测试在异常工况下的失效模式并评估对系统的影响。

六、选型提示

在选择 HR051142 时,请根据系统的输入电压范围、工作工况(开关频率、拓扑)与安全等级要求评估其适配性;如需更高绝缘等级或不同电压/功率规格,可与 HANRUN 技术支持联系获取产品系列及样片。对于批量生产,建议进行 PCB 样板验证与长期老化测试,确保在目标应用中的可靠性。

总结:HR051142 以其 13W 的 SMD 贴片结构、双路一次绕组设计和较低漏感,适合在小功率隔离电源中实现紧凑布局与可靠输出,但在设计与使用时需重视隔离等级、热管理与正确的绕组连接方式。若需完整引脚和机械图纸,请联系供应商索取详细资料。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
