B1205XT-2WR3 产品概述

一、主要特点

B1205XT-2WR3 是 YLPTEC(易川)推出的一款板载隔离型DC-DC转换器,支持100%全国产化。该器件为双路输出、总功率2W的非稳压型隔离电源模块,适用于对隔离要求高且对输出稳压要求不苛刻的场合。模块内置短路保护并具有自动故障恢复功能,开关频率260kHz,转换效率典型值79%,具有体积小、散热要求低、抗干扰能力强的特点。

二、产品参数

  • 输出通道数:2路
  • 总输出功率:2W
  • 输入电压范围:10.8V ~ 13.2V(典型12V输入)
  • 输出电压:5V(非稳压型)
  • 最大输出电流:400mA(在总功率限制内)
  • 最大容性负载:2400µF
  • 隔离耐压:1.5kV rms(相当等级耐压可达数千V DC)
  • 纹波噪声:50mV p-p
  • 开关频率:260kHz
  • 工作温度:-50℃ ~ +115℃
  • 保护功能:短路保护、自动故障恢复
  • 封装:SMD-5P,外形尺寸:12.7mm × 11.2mm × 7.25mm
  • 稳压类型:非稳压型(输入需稳定,见注意事项)

三、适用场合

该模块为专门针对板上电源系统中需要产生与输入电源隔离电压的应用而设计,典型适用场景包括:

  • 纯数字电路的隔离供电(如微处理器外设隔离)
  • 一般低频模拟电路场合(对噪声与精度要求不高)
  • 继电器、光耦、传感器等负载的驱动电源
  • 需要输入/输出隔离以保证安全或地线分离的工业控制与通信设备

四、使用注意事项

  • 本产品为非稳压型输出,要求输入电源在±10%Vin以内波动,以保证输出电压在允许范围内。
  • 输出总功率受限(2W),在并联或两路同时使用时须注意不超过总功率和最大输出电流限制。
  • 最大容性负载2400µF适用于大电容的去耦或继电器吸合,但建议根据实际负载与启动电流进行评估。
  • 虽具宽温特性(-50℃~+115℃),高温下应注意PCB散热与周边元件布局以避免热堆积,必要时留足铜面积或散热通道。
  • 隔离等级为1.5kV rms,请在系统设计中考虑耐压余量及工频脉冲、浪涌等影响,符合所需安全标准时方可直接采用。

五、封装与安装

SMD-5P 表面贴装封装,尺寸紧凑(12.7 × 11.2 × 7.25 mm),适合自动贴装与回流焊工艺。建议根据厂家推荐的焊盘图样和回流曲线进行PCB设计与装配,靠近散热需求位置预留散热铜箔并避免高热源元件旁侧布局。

六、优势与选型建议

  • 100%国产化,供应链可控,适合国产化替代方案。
  • 体积小、效率较高、带短路自恢复保护,适合工业级与商用板级隔离电源需求。
  • 若系统对输出电压精度或纹波噪声有较高要求,建议选择稳压型或添加后端LDO/滤波电路。
  • 在输入不稳或需更高耐压等级时,应选用更宽输入范围或更高隔离耐压的型号。

总体而言,B1205XT-2WR3 是一款面向板级隔离供电、应用广泛且国产化程度高的双路小功率DC-DC模块,适合在数字隔离、继电器驱动及一般工业控制场景中作为可靠的隔离电源解决方案。若需原理图接线示意、典型应用电路或焊盘尺寸图,可进一步提供以便优化设计。

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.

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
