H1205S-2WR3 产品概述

一、产品简介

H1205S-2WR3 是 YLPTEC(易川)推出的一款小体积、高效率、微功率的隔离型 DC/DC 模块。该模块为定电压、非稳压单路输出设计,专为板上需要与输入电源隔离的场合而开发,适用于以 12V 为工作母线的电子系统中提供 5V 隔离电源。模块体积紧凑(SIP 封装 19.5×9.8×12.5mm),便于在空间受限的板级电源设计中使用。

二、主要特性

  • 输入电压范围:10.8V ~ 13.2V(针对 12V 母线,推荐在 ±10% 范围内使用)
  • 输出:单路 5.0V,最大输出电流 400mA,输出功率 2W
  • 转换效率高达 88%,典型损耗约 0.27W(满载时)
  • 隔离耐压:6kVrms(输入与输出之间)
  • 开关频率:100kHz,低频噪声和 EMI 易于控制
  • 纹波与噪声:70mVp-p(典型值)
  • 最大容性负载:2400μF(支持较大滤波电容,但须注意启动与冲击电流)
  • 封装:SIP,体积小,便于通孔或插针固定安装
  • 工作温度范围:-40℃ ~ +85℃

三、电气性能要点

  • 本系列为隔离“非稳压”模块,输出随输入电压与负载变化存在一定偏差,适用于输入电压稳定(±10%)且对输出精度要求不高的场合。
  • 最高输出功率 2W,满载(400mA)工作时效率 约 88%,模块自身发热较低,但仍需考虑散热空间与环境温度对功率的影响。
  • 纹波噪声 70mVp-p,适合数字电路、逻辑接口与继电器驱动;对高精度、低噪放大器等敏感模拟电路并非优选。
  • 支持最大 2400μF 的容性负载,但较大电容会增加启动电流并可能影响模块启动性能,建议必要时在输入端/输出端加限流或软启动电路。

四、保护与可靠性

  • 短路保护:内置短路保护并具备自动故障恢复功能(故障消除后自动重启),便于系统长期运行。
  • 过热保护:当内部温度超过安全阈值时模块进行保护动作,防止损坏。
  • 隔离性能优良,适合需要高压隔离的板间或模块间供电。
  • 建议在系统设计中对长期高温或满载工况进行适当降额,以延长可靠性寿命。

五、典型应用场景与选型建议

  • 典型应用:板上隔离电源,数字电路供电(MCU、FPGA 外围)、继电器驱动、数据交换接口、通信模块供电,以及常见的低频模拟电路。
  • 选型建议:当输入母线稳定且对输出电压精度要求不高时优先考虑;若系统对输出稳压或低噪要求更高,应选用线性稳压器或精密隔离模块配合滤波。对于需更大输出电流或更高功率的场合,应选择额定功率更高的型号。

六、封装与安装注意事项

  • 尺寸:长 19.5mm × 宽 9.8mm × 高 12.5mm,SIP 引脚便于通孔焊接固定。
  • 安装时注意保持输入与输出间足够爬电距离与空气间隙以保证 6kVrms 隔离要求;高压环境下遵循 PCB 安全间距规范。
  • 布局建议:输入侧靠近母线进线并加适当去耦电容;输出侧若接大电容,建议串联小电阻以限制冲击电流;模块周围保留散热空间,避免元器件堆叠影响散热。

总结:H1205S-2WR3 以其小巧体积、高效率与 6kV 隔离特性,适合用于对隔离有明确需求且输入电压稳定的板级供电场景,是数字电路与常规驱动电路中常用的隔离型微功率 DC/DC 方案。

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
