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。
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:
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
