B0303S-1WR2 是 YLPTEC(易川) 推出的单通道隔离型直流变换模块,额定输出功率 1W,采用插件封装,适用于需要小型隔离电源的场合。模块输入电压范围为 2.97V ~ 3.63V,输出稳压 3.3V,最大输出电流 303mA,具有高可靠性和实用的保护功能,适配各种嵌入式与工业控制系统。
以上参数为典型值或最大值,实际使用时请参考具体工作点下的特性曲线与热设计条件。
模块具备短路保护功能,能在异常负载或短路时限制输出,保护负载与模块自身安全。工作温度范围宽(-40℃ ~ +105℃),适应工业级环境。由于效率为72%左右,在高负载条件下仍会产生一定热耗散(示例:在满载且按额定功率输出时,器件损耗约为0.39W),建议在设计时预留散热空间或采用通风/散热片等措施以保证长期可靠性。
适用于需要隔离的小功率电源场合,包括但不限于:
总结:B0303S-1WR2 为一款性能均衡、具有隔离与短路保护的小功率 DC-DC 模块,适合对体积、隔离要求较高且功耗在 1W 范围内的应用场景。若需进一步的引脚定义、典型电路或测评数据,可提供具体应用需求以便给出更详细的设计建议。

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.
